The main purpose of commonly used stainless steel grades

Grade type uses

1Cr18Ni9Ti is the most widely used austenite type for food, chemical, pharmaceutical and atomic energy industries.

0Cr25Ni20 Austenitic furnace material, material for automotive exhaust purification equipment

1Cr18Ni9 austenitic type with high strength after cold working, decorative parts for construction

0Cr18Ni9 Austenite type is widely used as stainless heat-resistant steel, food equipment, general chemical equipment, nuclear energy industry

00Cr19Ni10 Austenite type

Field open-air machines, building materials, heat-resistant parts, and heat-treating parts used in the chemical, coal, and petroleum industries that require high resistance to intergranular corrosion

0Cr17Ni12Mo2 Austenite type

Suitable for use in seawater and other media, mainly for pitting corrosion resistance, photography, food industry, coastal area facilities, ropes, CD rods, bolts, nuts

00Cr17Ni14Mo2 Ultra-low carbon steel with 0Cr17Ni12Mo2 austenite type, used for special requirements against intergranular corrosion


1Cr18Ni12Mo2Ti austenite type for anti-sulfuric acid, phosphoric acid, formic acid, acetic acid equipment, has good resistance to intergranular corrosion

0Cr18Ni12Mo2Ti Austenite type Ibid

0Cr18Ni10Ti Austenite-type addition of Ti improves resistance to intergranular corrosion and is not recommended as a decorative part

0Cr16Ni14 austenite type non-magnetic stainless steel for electronic originals

0-1Cr20Ni14Si2 Austenite Type

With high temperature strength and oxidation resistance, it is sensitive to sulphurous atmosphere and has a brittle tendency of precipitation phase at 600-800°C. It is suitable for making various furnace components that can bear stress.

1Cr17Ni7 austenitic type for high-strength components, materials for train passenger cars

00Cr18Ni5Mo3Si2 Austenite + Ferrite

Good resistance to stress corrosion cracking, high strength, suitable for environments containing chlorine ions, used in oil refining, fertilizers, papermaking, petroleum, chemical industries, manufacturing heat exchangers, condensers, etc.

0Cr17(Ti) ferrite is used for stamping parts of washing machine inner barrels, decorative

00Cr12Ti ferrite type for automotive muffler tubes, decorative

0Cr13Al ferrite type cooling from high temperature does not produce significant hardening, steam turbine material, parts for quenching, composite steel

1Cr17 ferrite type general-purpose steel with good corrosion resistance, for interior decoration, heavy oil burning parts, for home appliances, household appliance parts

0Cr13 ferrite type for higher toughness and impact load parts, such as turbine blades, structural frames, bolts, nuts, etc.

1Cr13 martensitic type

Good corrosion resistance, machinability, general purpose, blade mechanical parts, oil refining equipment, bolts, nuts, pump rods, tableware, etc.

2Cr13 martensitic quenching, high hardness, good corrosion resistance, as steam turbine blades, cutlery (knife)

Steel Structure Plant

SBS prefabricated building is a new type environmental friendly product that adopts steel structure as frames, various plates and panels as surrounding protection system, high strength bolts as component connection. The metal frame buildings are mainly used as modular house, office, cleaning workshop, cold storage room, wide span workshop, warehouse, exhibition hall,stadiums , hangars, steel-structure supermarkets, high-rise steel constructions, logistics center, container house and so on. SBS products are exported to more than 70 countries and regions covering Middle East, Africa, Southeast Asia, South America etc.
