904L Stainless steel Hexagonal steel super austenitic stainless steel contains 14.0-18.0% chromium, 24.0-26.0% nickel, 4.5% molybdenum. 904L super austenitic stainless steel is a low carbon high nickel, molybdenum austenitic stainless steel, for the introduction of France H·S company's proprietary material. It has good activation-passivation transition ability, excellent corrosion resistance, good corrosion resistance in non-oxidizing acids such as sulfuric acid, acetic acid, formic acid, phosphoric acid, good pitting corrosion resistance in neutral chloride ion medium, and good crevice corrosion resistance and stress corrosion resistance.

444 Stainless steel Hexagonal steel is an ultra-low carbon nitrogen, 18% chromium and 2% molybdenum, high corrosion resistance ferritic stainless steel. The steel is generally stabilized by niobium or titanium, which can avoid intergranular corrosion after welding. The steel is particularly suitable for use in various water treatment devices.

441 Stainless steel Hexagonal steel ferritic stainless steel has a very low carbon and nitrogen content, while adding trace amounts of the beneficial allogenic elements Nb and Ti. The lattice structure of SUS441(022Cr18NbTi) ferritic stainless steel is body-centered cubic, and its octahedral gap radius is only 0.15 times of the radius of Fe atom (face-centered cubic is 0.414 times), and the ability to contain gap compound particles is poor. Therefore, the carbonitride particles of Nb and Ti are easy to disperse and distribute in the matrix metal, which improves the comprehensive performance of stainless steel.

439 Stainless steel Hexagonal steel is based on the ordinary ferrite material (430) to reduce the content of C, while adding Ti and other stabilizing elements, so that the steel resistance to intergranular corrosion, formability and weldability are improved.

420J2 Stainless steel Hexagonal steel has certain wear resistance and corrosion resistance, high hardness, its price is the lower class of stainless steel ball, suitable for the common requirements of stainless steel working environment. Suitable for all kinds of precision machinery, bearings, electrical, equipment, instruments, meters, transportation, household appliances, etc. It is mainly used to make parts that are resistant to atmospheric, water vapor, water and oxidizing acid corrosion. 420J1 stainless steel: after quenching, high hardness, good corrosion resistance (magnetic) 420J2 stainless steel quenching, compared with 420J1 steel hardness increased (magnetic).

420J1 Stainless steel Hexagonal steel has certain wear resistance and corrosion resistance, high hardness, its price is the lower class of stainless steel ball, suitable for the common requirements of stainless steel working environment. Features and scope of application: It has certain wear resistance and corrosion resistance, high hardness, its price is the lower class of stainless steel ball, suitable for the common requirements of stainless steel working environment. Suitable for all kinds of precision machinery, bearings, electrical, equipment, instruments, meters, transportation, household appliances, etc. It is mainly used to make parts that are resistant to atmospheric, water vapor, water and oxidizing acid corrosion.

410S Stainless steel Hexagonal steel is a martensitic stainless steel. 410S(13Cr) has good corrosion resistance and machining performance, for general purpose steel, cutting tool steel. 410S is a kind of steel that improves the corrosion resistance and formability of 410 steel.

409L Stainless steel Hexagonal steel is highly resistant to corrosion, high temperature and fatigue, which can realize the longevity and lightweight of exhaust system components. 409L high temperature resistance, can achieve high efficiency of the engine and exhaust system, and reduce the thickness of the exhaust system, can reduce exhaust emissions. 409L low cost, good flexibility, high yield, easy to replace, belongs to the environmental protection of new products.

430 Stainless steel Hexagonal steel is a general steel with good corrosion resistance, thermal conductivity is better than austenite, thermal expansion coefficient is smaller than austenite, heat fatigue resistance, adding the stabilizing element titanium, good mechanical properties of the weld. 430 stainless steel for building decoration, fuel burner parts, household appliances, home appliance parts. 430F is a kind of steel with free cutting performance on 430 steel, mainly used for automatic lathes, bolts and nuts, etc. 430LX adds Ti or Nb to 430 steel, reduces the C content, improves the processing performance and welding performance, mainly used in hot water tank, hot water supply system, sanitary appliances, household durable appliances, bicycle flywheel, etc.
