The grades of heat-resistant steel include but are not limited to the following:
12Cr1MoV: This is a pearlitic low-alloy thermal strength steel with high thermal strength and oxidation resistance, and still has good performance at 580 ° C. It is mainly used in the manufacture of steam parameters 540℃ pipe, metal wall temperature less than 580℃ superheater tube and forgings.
310S: This is an austenitic chromium-nickel stainless steel with good oxidation resistance and corrosion resistance because it contains a high percentage of chromium and nickel, has good creep strength, and can be operated continuously at high temperatures. It is suitable for the production of various furnace components, the highest temperature can reach 1300℃, and the continuous use temperature is 1150℃.
06Cr23Ni3 and 06Cr25Ni20 (corresponding to 310 heat-resistant steel) : These grades of heat-resistant steel can withstand the high temperature of more than one thousand degrees, of which 06Cr23Ni3 heat resistance temperature can reach 1050 degrees, and 06Cr25Ni20 heat resistance temperature can reach 1200 degrees, can be used continuously below 1150 degrees, is the mainstream grade of heat-resistant steel.
X12CrNi23-13: This is an Austenitic heat-resistant steel with corrosion resistance, the old grade is ISO 4955:1994 standard grade. It corresponds to a variety of grades in other national and international standards, such as 06Cr23Ni13(0Cr23Ni13), S30908, 309S, SUS 309S, etc.
Q690FRWB: This is a refractory weathering steel with high yield strength, where Q represents the first letter of the yield strength and 690 represents the specified minimum upper yield strength value.
These heat-resistant steel grades cover different types from low alloy steel to stainless steel and are suitable for a variety of high-temperature working environments, including industrial furnaces, chemical equipment, power generation and other fields.
