View full details

15-5 PH stainless steel is a martensitic precipitation-hardening stainless steel with
approximately 15% Chromium and 5% Nickel. It has high strength, high hardness, and excellent corrosion resistance. Strength can be further increased by a single low temperature heat treatment. Compared to 17-4 PH, it offers better transverse toughness and ductility; better
mechanical properties in larger cross-sections, and better forgeability. It is readily weldable. It
can be machined in any of the several Thermal Conditions available to this grade.

available in several forms including stainless steel round bar, flat bar, and square bar as well as stainless steel plate, sheet, block, and billet

Certifications & Compliance

Quality, traceability, and compliance are at the core of our platform. We ensure that all
materials and suppliers meet internationally recognised standards, giving you confidence in
every transaction.
Our network supports materials certified to major global standards such as ASTM, AMS,
BS/EN, and ISO, with full documentation available where required. Suppliers are expected to
maintain relevant quality certifications (including ISO 9001 and other industry-specific
approvals), ensuring consistent manufacturing and testing practices.
We facilitate access to key documentation, including:


• Mill Test Certificates (MTC)
• Certificates of Conformity (CoC)
• Material Traceability Records
• Inspection & Quality Reports

For sectors such as aerospace and defence, we also support enhanced compliance
requirements, including lot traceability and audit-ready documentation.
