410
Stainless steel 410 is produced according to American ASTM
standard, equivalent to China's 1Cr13 stainless steel, S41000
(American AISI, ASTM).Carbon 0.15%, chrome 13%,410 stainless steel:
good corrosion resistance, machinability, general purpose blade
class, valve class.Heat treatment of 410 stainless steel: solid
solution treatment (℃) 800-900 slow cooling or 750 fast
cooling.Chemical composition of 410 stainless steel:
C≤0.15,Si≤1.00,Mn≤1.00,P≤0.035,S≤0.030,Cr=11.50~13.50.
416
416 stainless steel is a kind of steel with good cutting
performance in stainless steel. 416 stainless steel is mainly used
in the production of solenoid valves, micro-special motors and
electrical components.The above materials are free cutting
stainless steel, especially suitable for automatic lathes, CNC
lathes mass production.

420
420 stainless steel is a kind of martensitic stainless steel, with
certain wear resistance and corrosion resistance, high hardness
characteristics, suitable for all kinds of precision machinery,
bearings, electrical, equipment, instruments, instruments,
transportation vehicles, household appliances.
It is mainly used in manufacturing components that are resistant to
corrosion by air, water vapor, water and oxidizing acid.

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%

(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
