17-4PH 630 Stainless Steel Sheet Plate

17-4PH stainless steel plate heat treatment

‌Solution treatment: heating at 1020~1060℃, followed by rapid cooling. The structure after solution treatment is mainly quenched martensite + residual austenite + a small amount of ferrite. ‌After aging treatment, fine and dispersed strengthening phases are precipitated in the alloy, effectively improving the strength and hardness of the alloy. ‌

 

630 stainless steel plate application areas ‌

Aerospace: used to manufacture aircraft structural parts and engine parts. ‌

Petrochemical: used to manufacture pipelines, valves and reactors under high temperature and high pressure. ‌

Marine engineering: used to manufacture offshore platforms, ships and diving equipment, etc.
