Main applications of common stainless steel gradesGrade Type Applications
1Cr18Ni9Ti Austenitic Most widely used; suitable for the food, chemical, pharmaceutical, and nuclear industries
0Cr25Ni20 Austenitic Materials for furnaces and automotive exhaust purification systems
1Cr18Ni9 Austenitic High strength after cold working; used for decorative building components
0Cr18Ni9 Austenitic Widely used as a stainless heat-resistant steel; for food processing equipment, general chemical equipment, and nuclear industry applications
00Cr19Ni10 Austenitic Used in chemical, coal, and petroleum industries where high resistance to intergranular corrosion is required; for outdoor machinery, building materials, heat-resistant parts, and parts that are difficult to treat thermally
0Cr17Ni12Mo2 Austenitic Suitable for use in seawater and other media; primarily used as a material resistant to pitting corrosion; used in the photography and food industries, as well as in coastal facilities, ropes, CD rods, bolts, and nuts
00Cr17Ni14Mo2 Austenitic A super-low carbon version of 0Cr17Ni12Mo2; used for products with special requirements regarding resistance to intergranular corrosion
1Cr18Ni12Mo2Ti Austenitic Used in equipment exposed to sulfuric acid, phosphoric acid, formic acid, and acetic acid; has good resistance to intergranular corrosion
0Cr18Ni12Mo2Ti Austenitic Same as above
0Cr18Ni10Ti Austenitic Ti addition improves resistance to intergranular corrosion; not recommended for use as decorative components
0Cr16Ni14 Austenitic Non-magnetic stainless steel; used in electronic components
0-1Cr20Ni14Si2 Austenitic Has high strength at high temperatures and good oxidation resistance; sensitive to sulfur-containing atmospheres; tends to become brittle due to phase precipitation at 600–800°C; suitable for manufacturing various furnace components under stress
1Cr17Ni7 Austenitic Suitable for high-strength components; used in train carriages
00Cr18Ni5Mo3Si2 Austenitic+Ferritic Good resistance to stress corrosion cracking; high strength; suitable for environments containing chloride ions; used in industries such as oil refining, fertilizer production, papermaking, petroleum, and chemicals; used for manufacturing heat exchangers and condensers
0Cr17(Ti) Ferritic Used for stamping parts in washing machine drums; for decorative purposes
00Cr12Ti Ferritic Used in automotive exhaust silencer tubes; for decorative purposes
0Cr13Al Ferritic Does not show significant hardening when cooled from high temperatures; used as turbine materials, quenching components, and in composite steels
1Cr17 Ferritic A general-purpose steel with good corrosion resistance; used for interior building decorations, heavy oil combustion components, household items, and home appliance parts
0Cr13 Ferritic Used for parts requiring high toughness and resistance to impact loads, such as turbine blades, structural frames, bolts, and nuts
1Cr13 Martensitic Has good corrosion resistance and machinability; used for general purposes, cutting tools, petroleum refining equipment, bolts, nuts, pump shafts, and tableware
2Cr13 Martensitic High hardness in the quenched state; good corrosion resistance; used for turbine blades and tableware (knives)
