为制造在腐蚀性介质中工作的重型机器和动力机器,苏联中央工艺与机器制造科研所研制了一系列新型耐蚀钢和保护金属涂层。新型铬锰奥氏体钢50和59能延长用重油和页岩作燃料的蒸汽过热器的工作寿命达10万小时,延长用含硫煤作燃料的蒸汽过热器的使用寿命达20万小时。03Х22Н284Т(86)耐热钢用于制造燃烧设备的焊接外罩,以及耐1300℃高温的结构件。这种钢的薄板经氩弧焊焊成的燃烧机器外壳,使用2年后仍保持完好。改良型可耐热达900℃的超低碳889钢,主要是添加了2～3％Al,从而保证了该钢在含C高达0.1％时仍可保持高耐热性和工艺性,由于可用普通炉料,并可在电弧炉中熔炼,从而大大降低了成本。超级铁素体904-钢可取代Х23Н18钢,用于制造大型蒸汽
For the manufacture of heavy machinery and power machinery working in corrosive media, a series of new types of corrosion-resistant steel and protective metal coatings were developed by the Soviet Central Institute of Process and Machinery Manufacturing. The new chromium-manganese austenitic steels 50 and 59 extend the service life of a steam superheater that uses heavy oil and shale for 100,000 hours and extend the service life of a steam superheater containing sulfur-bearing coal for 200,000 hours. 03Х22Н284Т (86) Heat-resistant steels Welding housings for the manufacture of combustion equipment, as well as structural components resistant to temperatures up to 1300 ° C. This steel sheet by argon arc welding into the burning machine casing, after 2 years still intact. The modified ultra-low carbon 889 steel, which is resistant to heat up to 900 ° C, is mainly composed of 2 to 3% Al added, thus ensuring that the steel retains its high heat resistance and processability even with C up to 0.1% Ordinary charge, and smelting in the electric arc furnace, thus greatly reducing costs. Super ferrite 904-steel can replace Х23Н18 steel, used to make large-scale steam
