What Is 17-4 PH Stainless Steel?
17-4PH (UNS S17400 / Grade 630) is a martensitic precipitation-hardening stainless steel combining high strength, corrosion resistance, and excellent hardness — achievable through a single low-temperature aging treatment. The "17-4" designation refers to its approximate composition: 17% Chromium and 4% Nickel.
Nifty Alloys LLC supplies 17-4PH stainless steel bars and plates in all standard heat treatment conditions — H900, H1025, H1075, and H1150 — with EN 10204 3.1 Mill Test Certificates. We serve UAE, Saudi Arabia, Qatar, Kuwait, Oman, Bahrain, and global export markets.
