If you have stainless steel parts machined we are one of the most capable and affordable sources.

Which stainless steel types are popular ?

Austenitic stainless steel: marked by 200 and 300 series number. Its microstructure is austenite. Common types are the following:


Advantages: easy to welding, good plasticity (not easy to break), deformation, good stability (not easy to rust), easy passivation.

Disadvantages: particularly sensitive to medium in solution that has chloride, prone to stress corrosion.

Ferritic stainless steel: marked by 400 series number. Its internal microstructure is ferrite, and its chromium mass fraction is in the range of 11.5% ~ 32.0%.

Common types are the following:


Advantages: high chromium content, good thermal conductivity, stability is better, good heat dissipation.

Disadvantages: poor mechanical properties and process performance.

Martensitic stainless steel: marked by 400 series number. Its microstructure is martensite. The mass fraction of chromium in this kind of steel is 11.5% ~ 18.0%.

Common types are the following:

1Cr13(410)、2 Cr13(420)、3 Cr13、1 Cr17Ni2

Advantages: high carbon content, high hardness.

Disadvantages: poor plasticity and weldability.
