Detailed introduction of ASTM A564 17-4PH Stainless Steel Bar:

 

We can customize and process ASTM A564 17-4 PH Round Bar according to customer requirements, with high standards and high quality. Main products: AMS 5643 17-4 PH Round Bar, Stainless Steel Grade 630 Round Bar, ASTM A564 UNS S17400 Bright Bars,ASTM A564 17-4PH Stainless Steel Round Bar.


Overview of 17-4PH stainless steel round bars:


17-4PH is a precipitation hardening steel material with high strength, high hardness, good welding performance and corrosion resistance. It has been widely used in valves, shafts and chemical fiber industries, and high-strength parts with certain corrosion resistance requirements.


17-4PH is a precipitation hardening martensitic stainless steel composed of copper, niobium/columb, with low carbon content, better corrosion resistance and weldability than general martensitic stainless steel, similar to 18-8 stainless steel, heat treatment process Simple and good machinability, but it is difficult to satisfy cryogenic processing.


Features: Precipitation hardening steel with copper added. Used in the manufacture of shafts and steam turbine parts.


Chemical Composition of Stainless Steel Grade 630 Round Bar:

17-4PH belongs to the chemical composition of precipitation hardening steel materials:
