630 Stainless steel tube manufacturer
Stainless steel 630 is martensitic precipitation hardening stainless steel.
630 stainless steel performance characteristics is easy to adjust the strength level, can be adjusted through the change of heat treatment process, martensitic transformation and aging treatment of precipitation hardening phase is the main means of strengthening, 630 stainless steel attenuation performance is good, corrosion fatigue and water drop resistance performance.

630 stainless steel is precipitated, hardened, martensitic stainless steel.
630 stainless steel is a precipitated, hardened, martensitic stainless steel composed of copper, niobium/coltan.
This grade has high strength and hardness (up to 300º);
C/572º
F) and corrosion resistance and other characteristics.
After heat treatment, the mechanical properties of the product are more perfect, which can reach the compressive strength of up to 1100-1300 MPa (160-190 ksi).
This level cannot be used above 300º
C (572º
F) or very low temperature, it has good corrosion resistance to the atmosphere and dilute acid or salt, its corrosion resistance is the same as 304 and 430.
Application field
· Offshore platforms, helicopter decks and other platforms
· Food industry
· Pulp and paper industry
· Aerospace (Turbine Blades)
· Mechanical parts
· Nuclear waste bins
Stainless steel 630 is a precipitated, water-quenched, martensitic stainless steel, and this grade has high strength, hardness and corrosion resistance.
After heat treatment, the mechanical properties of the product are more perfect, which can reach the compressive strength of up to 1100-1300 MPa (160-190 ksi).
This grade should not be used at temperatures higher than 300 ° C (570F) or very low temperatures. It has good corrosion resistance to atmosphere and dilute acids or salts. It has the same corrosion resistance as 304 and 430.
