630 ss seamless tube

630 stainless steel is a martensitic precipitation hardening stainless steel. The performance characteristics of 630 stainless steel are that it is easy to adjust the strength level, which can be adjusted by changing the heat treatment process. Martensitic transformation and aging treatment to form a precipitation hardening phase are its main strengthening methods. 630 stainless steel has good attenuation performance, corrosion fatigue resistance and water drop resistance. powerful.

630 stainless steel is a precipitation, hardened, martensitic stainless steel.
630 stainless steel is a precipitated, hardened, martensitic stainless steel composed of copper, niobium/columbium.
This grade offers high strength, hardness (up to 300º C/572º F) and resistance to corrosion.
After heat treatment, the mechanical properties of the product are more perfect and can reach a compressive strength of up to 1100-1300 mpa (160-190 ksi).
This grade cannot be used at temperatures above 300ºC (572º F) or at very low temperatures. It has good corrosion resistance to both the atmosphere and dilute acids or salts. Its corrosion resistance is the same as 304 and 430.

product feature

630 stainless steel is a precipitated, quenched, martensitic stainless steel, and this grade has high strength, hardness and corrosion resistance. After heat treatment, the mechanical properties of the product are improved and can reach a compressive strength of up to 1100-1300 mpa (160-190 ksi). This grade cannot be used at temperatures above 300°C (570F) or at very low temperatures. It has good corrosion resistance to the atmosphere and dilute acids or salts. Its corrosion resistance is the same as 304 and 430.

Precipitation hardening steel with added copper. Used for manufacturing shafts and steam turbine components.

Precipitation hardening martensitic stainless steel composed of copper, niobium/columbium, has low carbon content, better corrosion resistance and weldability than ordinary martensitic stainless steel, is similar to 18-8 stainless steel, has a simple heat treatment process and is easy to cut Good performance, but difficult to meet cryogenic processing requirements.

Metallographic structure: The structure is characterized by precipitation hardening.
