17-4PH Stainless Steel Plate AISI 630 Condition A Hot Rolled Precipitation Hardening 6-100mm

17-4PH Stainless Steel Plate (AISI 630) — Condition A

17-4PH (AISI 630 / UNS S17400) is a precipitation hardening martensitic stainless steel plate combining high strength with excellent corrosion resistance. This plate is supplied in Condition A (solution annealed) and hot rolled, ready for subsequent aging treatment (H900–H1150) and machining. It delivers a good balance of strength, toughness and corrosion resistance in chemical, petrochemical and mechanical applications.

Key Features

• High strength achieved by simple aging heat treatment after machining
• Excellent corrosion resistance, better than 410 and comparable to 304 in many media
• Good machinability and dimensional stability during aging
• Suitable for high‑stress parts such as valves, pumps and shafts
• MTC to EN 10204 3.1 and third‑party inspection (SGS/BV) available
