434 stainless steel has good corrosion resistance and general purpose steel, thermal conductivity is better than austenite, thermal expansion coefficient is smaller than austenite, heat resistance fatigue, adding stabilized element titanium, welding site mechanical properties is good.434 stainless steel used for building decoration, fuel burner parts, household appliances, household appliances parts.

440B stainless steel has higher hardness and toughness than 440C stainless steel, used for cutting tools, measuring tools, bearings and valves.Suitable for bayonet blade.The carbon content and hardness of 440A-440B-440C are gradually increased (0.75%-0.9%-1.2%).

430 is Ferrite stainless steel, with a good corrosion resistance of common steel, thermal performance than austenitic good,.Because of its chromium content, it is also called 18/0 or 18-0.It’s used in Building decoration, fuel burner parts, household appliances, household appliances.
