430
430 stainless steel is a universal steel with good corrosion resistance, better thermal conductivity than austenite, smaller coefficient of thermal expansion than austenite, thermal fatigue, add stabilizing element titanium, welding seam mechanical properties.
430 stainless steel for building decoration, fuel burner components, household appliances, household appliances components.
The 430F is a type of steel with free cutting properties on 430 steel, mainly used in automatic lathes, bolts and nuts.
430LX adds Ti or Nb to 430 steel, reduces C content, improves processing performance and welding performance, mainly used for hot water tank, heating water system, sanitary appliances, household durable appliances, bicycle flywheel and so on.
Because of its chromium content, it is also called 18/0 or 18-0.
Compared with 18/8 and 18/10, the chromium content is slightly lower and the hardness is correspondingly lower.
chemical component:
(C) :≤0.12%
(Si) :≤0.75%
(Mn) :≤1.00%
(P) :≤0.040%
(S) :≤0.030%
(Ni) :≤0.60%
(Cr) :16.00~18.00%

440C
440C steel is a martensitic stainless steel.
Carbon content 1.0%, chromium content 16-18%.
Strong rust resistance, is high - quality stainless steel.
Scope of application: mainly used for manufacturing bearing parts in corrosive environment and strong oxidation atmosphere without lubrication.
The 440C has good dimensional stability at high temperature, so it can also be used as corrosion-resistant high temperature bearing steel.
In addition, it can also be used to make high-quality knives, such as surgical knives, scissors, nozzles, bearings and so on.
The capacity of 440C to bear dynamic load is low
