13-8PH 1.4534 Martensitic Precipitation-Hardening Stainless Steel
Premium Quality by FUSHUN METAL
Advanced Manufacturing Excellence
As a leading Chinese manufacturer of specialty stainless steels, FUSHUN METAL produces high-quality 13-8PH martensitic precipitation-hardening stainless steel through advanced double-melting processes including Vacuum Induction Melting followed by Vacuum Arc Remelting (VIM-VAR) or Electroslag Remelting (ESR) techniques. This premium alloy demonstrates exceptional strength, high hardness, superior toughness, and excellent corrosion resistance comparable to 304 stainless steel, with optimal performance achieved in the fully hardened condition.
Our 13-8 PH steel features outstanding transverse toughness properties through precise chemical composition control, low carbon content design, and vacuum melting technology, offering a wide range of mechanical properties through single precipitation hardening heat treatment. The material exhibits excellent weldability with helium gas shielding recommended for optimal results, and maintains corrosion resistance similar to standard austenitic grades.
