ABSTRACT: Conventional forging and rolling of large stainless-steel rings with a
cross-section up to 900 m2 presents serious difficulties and sometimes is simply
c
impossible. Therefore, a method for making such rings by electroslag -welding has
been developed and introduced into practice. According to this method the ring is
assembled from several forged or rolled segments which are bent to a required radius.
A mold is built around each joint. The welding is done with a flat electrode and
a calcium fluoride-calcium oxide flux. With careful assembly the deformations can
be kept to a minimum. The method can be used for rings of any diameter and cross
section. Rings ofthe same diameter can be put on top of each other and ~,fflded as
a single ring. The method has been successfully used in welding MANIORteel
rings 3000 and 900 mm in diameter with respective cross sections of 195 x 195 and
60 x 110 mm, and Khl8NlOT Ateel rings with cross sections of 220 x 220 and

Pivent., V.D. [Candidate of Technical Sciences]. Automatic Coubustion-
Control System Operating on the Rate of Variations of the Controlled
Parameter 3
The author's nodification of an ordinary control system is based on
the use of double-acting regulators of the Pblzunov type,, intended
for 136sitive self-balancing processes. It is proven that such systems
are also applicable to negative [out-of-balancel processes, which are
exxtomatically corrected'so as to regain the proper ratios between the
quantities under control. This "flowmatic" type of control operates
on the variations in the rate of steam flow from the boiler.

TEXTs The article describes creep tests to fracture madewith welded
joints of inexpensive austenitic steels developed in the CSSR for
superheater tubes and forgings used in thermal power plants operating 4ith
high steam parameters. The VUW, V~zkumn~ U'stav )~iitnictvi Zveleza. (VURZ,
Ferrous Metallurgy Research Institute) and the Vftk-P-icke' 'z"elezirny
Klementa Gottwalda (Klement Gottwald Vitkovice Iron Works) developed the
174819 17482, and 17483 inexpensive, high~temperatureq austenitic, Mn-Cr
steels alloyed with Ti, V . and Mo. This,paper deals especially j~ith
suitcble filler metals developed by the VUZ, V~zkumn~ fistav zvhracsky

properties of welded joints at elevated temperatures. Creep tests to
fracture revealed that welded joints of superheater tubes have the same
creep strength as the 17482 and 17483 base metals when filler metals
MnCrMo(Nb) 17/7 and MnCrV(Nb) 17/10 are used. For welding 17481, 17482,
and 17483 austenitic-steel tubes to CSN 15 225 farritic-pearlitic-steel
tubes, the VZU ZVIL, Vkzkumnk a zkus~ebny U'stav Z&voduo V.I. Lenina (VZU-ZVIL,
Research and Testing Institute of the V.I, Lenin Works) developed a VZU 60
filler metal which contains a maximum of 0.110% C, 0.30% Mn, 0-80% Si,
19% Cr, 1.50/0. Ti, 15.W. Fe, 5.0% W+Mo, O.8W- Al, and balance Ni. It was
found that the long-term creep strength of such a weld is determined by the
creep strength of the transition zone of the 15 225 ferritic-pearlitic stee;
which is approximately 206 lower than the mean creep strength of the base
metal in the not-affected zone. Engineer J. Kouckk of the Ferrous
Metallurgy Research Institute is the personality mentioned. There are 6
figures, 9 tables and 10 Soviet-bloc references. (Technical Editor.

The laborntory experiments were carried out with two series of
heats, one produced in a 100-1cZ high-frequency furnace,
cast into in.mots and formed by forSiu-, and rollin- into 20-mm
diametcr rods; the second series was produced in an 8-1-,g high-

dia-meter rod. In both series the rod ;'%-rere austanized at 1 050
to 1 070 0C for I hour, followed by cooling in air. These
experiments revealed that the corrosion resistance in the passive

mastering the manufacture of seamless tubes from these steels
at V2KG and Wi, Chomutov. A new technology was developed of'
manufacturing semis for the production of seamless tubes.
According to this technology, the heats are utilized for
teeming roll-mill ingots, type VI A,, weighing about 3 700 kg,
which are rolled into blooms-of 130 mm diameter. These are
rough-machined and split into blocks which are used for making
hollow pressEngs with-a bottom. Seamless tubes are~rolled
from these by current methods. On the basis of experience

ABSTRACT: The author deseribes the results obtained in
Czechoslovakia with CrMn economy steels developed for
manufacturing siperheater tubes which have to withstand
the effect of superheated steam and of combustion gases.
The development of austenitic ec~onomy steels began in
Czechoslovakia in the Vitkovice Steel Works -in 194-9.
MnCr steels were alloyed with up to 0.25% N and
stabilization was effected by means of Nb and Ta. The
creep strength at 650-700 00 practically equalled that
of austenitic Cr-Ni (Ta, Nb) 16/13 steel, Due to the
great shortage of Ta and Nb in Czechoslovakia, further
research work was carried..out fordeveloping titanium
stabilized Mn-Cr steels, Mn--Cr (Ti) 17/7 (steel 174-81
Card of the Czechoslovakian standard specification). The
115 heat conductivity of this steel is about 22 kcal/m OG
hour in the temperature range 300-550 OC, which is
considerable compared to the published values Ifor..

austenitic steels. According to the test results of
B. Prwenosil (Ref 10) this steel resists oxidation in
superheated steam of 180 atm up to the temperatures
6lo-630 OC, and up to 660 OC it resists oxidation in a
medium consisting of flue gases with a low content of
Sulphur and a relatively high content of water vapour.
According to the results of Prenosil and the author of
this paper, in the air the steel resists oxidation up to
740-800 OC. In Fig 2 the creep strength of this steel
is plotted for durations of 10 000, 25 000 and 100 000
hours. For temperatures above 620 OC and durations
exceeding 100 000 hours the values are extrapolated by
means of the Larson-Miller parameter. This Mn-Cr (Ti)
17/7 steel is suitable for tubes in forgings intended to
Card operate at a maximum temperature of 620 OC, i.e. for
2/5 superheated tubes (560 OC) up to 180 atm. For higher
steam parameters a.further austenitic high-temperature
Mn-Cr-V'17/10 economy steel was aeveloped; the
Pilot plant development of this steel was carried out in
the Witkovice Steel Works in cooperation with the

contains about 0.10% C, 1.8% Mn, 10% Gr, o.6o% v. It has
stable austenit-ic structure in the temperature range of
technological processing as well as in the range of
operating temperatures under consideration. According
to the test results of B. Prenosil, the Mn-Cr-V 17/10
steel withstands oxidation under the effect of steam
superheated to 700 OC (180 atm); inside combustion
products with a high content of water vapour it withstands
oxidation up to 7500C' and in air it restricts oxidation even above
750 OC. The bigb temperature stability of the Yin-Cr-V
steel was determined by long-run creep tests until
failure at 650, 700 and 750 OG for a laboratory 100 kg

austenitic steel has a very high ductility under creep
conditions, it has very high values of extension and
contraction during fracture and these values drop little
with increasing times to failure. It was established
that this steel is suitable for forgings and tubes
intended to operate at material temperatures up to
675 OC, i.e. for superheater tubes of high parameter
steam of 600-625 OC. In the graph of Fig 5 the
properties of the here-described economy steels with
austenitic Cr-Ni steels are compared. As regards creep
strength the Czech Mn-Cr-V 17/10 steel is equal to the
American steel AISI 347 or 348. In the Research Institute
for Shaping Metals in Zwickan (East Germany) the
possibility has been confirmed of producing seamless

TITLE: Development of Low Cost Austenitic Creep Resisting Steels
in Czechoslovakia
PERIODICAL: Hutnick/e listy, 1959, Nr 12, pp 1121-1123
ABSTRACT: Paper presented at the "Symposium on Problems of
of Creep-Resisting Materials",
316ske" Lazne, September 11-13, Section III.
1959.
Since 1949 the research and development of austenitic
creep resisting steel in Czechoslovakia covered not only
Cr-N! steels but also N! free Cr-Mn steels. In the case
of the latter type of steel the aim was to balance the
content of chromium and other ferrite forming elements
with,the manganese content so as to obtain a stable
austenitic structure, both at operating and at annealing
and hot working temperatures and to eliminate the
0
tendency to formation of a-phasef6-ferrite. Up to now
the following steels of this type have been developed:
manganese-chromium-nitrogen (-tantalumrniobium) 17/10
(N 7430); manganese-chromium (-titanium) 17/7 (CSN 17481);
manganese-chromium-vanadium 17/10; manganese-chromium-
Card 1/3 molybdenum-vanadium 17/7, The compositions of these steel's

are entered in Table 1, p 1121. Oxidation and corrosion
tests in atmospheres of air, combustion gazes and
superheated steam have shown that the growth of oxide
layers on austenitic Fe-Cr-Mn-base steels obeys
essentially the parabolic law. However, the temperature
dependence of the oxidation rate differs from that of
chromium and Cr-Ni steels and is characterized by a
sharp rise which sets in from a certain "critical"
temperature onwards, which depends on the compositionoof
the steel and the oxidation medium. The creep resistance
has been determined on laboratory, pilot plant and full
scale production melts for test durations up to 20 000 hours,
which have been extrapolated to 100 000 hours by means of
the Larson-Muller parameter using constant C values,which
were calculated for each type of steel. The production
technology has been developed and tested on a full
production scale for seamless tubes. Argon arc welding
of superheater tubes using Mn-Cr-Mo (nioblum) 17/7 filler
material has been developed and is being used under shop
Card 2/3 and erection conditions for the Mn-Cr (Ti) 17/7 steel. K
