Product Description

3mm*1200mm SUS630 Martensitic Stainless Steel plate  X5CrNiCuNb16-4 plate for high corrosion resistance helideck

Chinese Grade: 0Cr17Ni4Cu4Nb

(UNS S17400, AISI 630, AMS5643, ASTM A705, ASTM A564)

 

SUS630(Japanese Grade)is martensitic precipitation hardening stainless steel. It has high strength, high hardness, good welding performance and corrosion resistance. It has been widely used in valve, shaft, chemical fiber industry and high strength parts with certain corrosion resistance requirements.

 

Country	China	America	Japan	Europe
Grade	0Cr17Ni4Cu4Nb	ASTMS17400	SUS630	X5CrNiCuNb16-4

 

Characteristics and Usage:

 

a)     Precipitation hardening stainless steel with copper is used for manufacturing parts with high corrosion resistance and high strength, such as bearings and steam turbine parts.

b)     Precipitation hardening martensitic stainless steel with copper and niobium has low carbon content, its corrosion resistance and weldability is better than that of common martensitic stainless steel. Similar to type18-8 stainless steel, its heat treatment process is simple and the machinability is good, but it is difficult to meet the cryogenic processing.

 

Metallographic Structure: precipitation hardening type

 

Application Industry: offshore platform, helideck, other platforms, food industry, pulp and paper industry, aerospace (turbine blade), mechanical parts and nuclear waste barrel

Heat Treatment

SUS630 alloy is precipitated, Quenched and martensitic stainless steel with high strength, hardness and corrosion resistance. However, its mechanical properties which can reach the compressive strength of 1100-1300 MPa (160-190 Ksi) will be more perfect through heat treatment.

This grade cannot be used at temperatures higher than 300 ºC (570F) or at very low temperature. Its corrosion resistance is the same as that of 304 and 430 in normal atmosphere, diluted acid or salt.
