Introduction to commonly used stainless steel grades, types, and applications

1Cr18Ni9Ti Austenitic type, the most widely used, suitable for food, chemical, pharmaceutical, and atomic energy industries;

0Cr25Ni20 Austenitic type, material for furnaces and automotive exhaust purification devices;

1Cr18Ni9 Austenitic type, has high strength after cold processing, used for decorative components in construction;

0Cr18Ni9 Austenitic type, the most widely used stainless heat-resistant steel, for food equipment, general chemical equipment, and atomic energy industry;

00Cr19Ni10 Austenitic type, used for outdoor machines in the chemical, coal, and petroleum industries that require high resistance to intergranular corrosion; building materials; heat-resistant parts; and parts that are difficult to heat treat;

0Cr17Ni12Mo2 Austenitic type, suitable for use in seawater and other media; mainly used as a material resistant to pitting corrosion; applicable in photography, food industry, coastal facilities; ropes; CD rods; bolts; nuts;

00Cr17Ni14Mo2 Austenitic type is an ultra-low carbon steel of 0Cr17Ni12Mo2; used for products with special requirements against intergranular corrosion;

1Cr18Ni12Mo2Ti Austenitic type is used for equipment resistant to sulfuric acid, phosphoric acid, formic acid, acetic acid; has good resistance to intergranular corrosion;

0Cr18Ni12Mo2Ti Austenitic type same as above;

0Cr18Ni10Ti Austenitic type adds Ti to improve resistance to intergranular corrosion; not recommended as decorative components;

0Cr16Ni14 Austenitic type non-magnetic stainless steel; used for electronic components;

-1Cr20Ni14Si2 Austenitic type has high high-temperature strength and oxidation resistance; sensitive to sulfur-containing atmospheres; prone to embrittlement due to phase precipitation at 600-800℃; suitable for making various furnace components that bear stress;
