The different between 410 and 430 stainless steel
410 stainless steel is produced in accordance with the ASTM standard stainless steel grades, the equivalent of 1Cr13 stainless steel, S41000 (US AISI, ASTM). Carbon content of 0.15%, chromium 13%, 410 stainless steel: a good corrosion resistance, machinability, general purpose blade type, valve type. 410 stainless steel heat treatment: solution treatment (℃) 800-900 750 slow cooling or rapid cooling. 410 stainless steel chemical composition: C≤0.15, Si≤1.00, Mn≤1.00, P≤0.035, S≤0.030, Cr = 11.50 ~ 13.50.
430 stainless steel is a good corrosion resistance of common steel, thermal performance than austenitic good, thermal expansion coefficient than austenitic small, heat fatigue, add stabilization element titanium, weld parts mechanical performance is good. 430 stainless steel used in architectural use, fuel burner parts, household appliances, home appliance parts. 430F is easy to add cutting steel on 430 steel, mainly used for automatic lathe, bolts and nuts. 430LX added steel 430 Ti or Nb, lower C content, improve the processing performance and welding performance, mainly for the hot water tank, hot water systems, sanitary ware, household durable appliances, bicycles flywheel.
Because of its chromium content, also known as 18/0 or 18-0. Compared with 18/8 and 18/10, slightly less chromium, hardness reduced accordingly.
