Brief Introduction​ Of SUS630:

a) SUS630:

Martensitic precipitation hardening stainless steel.High strength, high hardness, good weldability and corrosion resistance.It has been a lot of extended used in valves, axial and chemical fiber industry and has certain corrosion resistant requirements of high strength parts, etc.

b) Stainless steel SUS630 features :

Add copper precipitation hardening steel.Used in the manufacture of axial, steam turbine parts.

Made of copper, niobium/coltan precipitation hardened martensitic stainless steel, carbon content is low, weldability and corrosion resistance than the average markov shape stainless steel, in 18 8 stainless steel, heat treatment process is simple, good machinability, but name is difficult to meet the deep, cold processing.

c) Stainless steel SUS630 purposes:

Used in the manufacture of high corrosion resistance, high strength of parts and components, such as bearings, turbine parts.ng and processing.

d) Stainless steel SUS630 delivery status:

General with heat treatment state delivery, its heat treatment type specified in the contract;Not specified, the heat treatment state delivery.

Applications:

We,this type bars be widely used in kinds of industries:

1. Petroleum,
2. Chemical industry,
3. Water treatment,
4. Food,
5. Paper making,
6. Machinery,
7. Municipal engineering,
8. Aerospace, medical,
9. Military and other industries
