17-4PH stainless steel sheet price (latest update 2026)

The current market price for 17-4PH (EN 1.4542 / UNS S17400) stainless steel sheet ranges from $4,200 to $5,000 per metric ton​ (FOB major Chinese ports), depending on thickness (0.5–50 mm), size (up to 2,000 × 4,000 mm), surface finish (2B, No.4, or mirror), and whether it is in solution-annealed or peak-aged (H900) condition, with mill test certificates (EN 10204 3.1) and additional processing (cut-to-size, leveling) adding ~5–10 % to the base price.

 

What is 17-4PH stainless steel sheet?

17-4PH stainless steel plate is a precipitation-hardening martensitic stainless steel containing 17% chromium and 4% nickel, along with copper for enhanced hardness. It offers high strength, good corrosion resistance (comparable to Type 304 stainless steel), excellent toughness, and retains good mechanical properties at elevated temperatures (up to 600°F/316°C). These properties are achieved through a specific low-temperature heat treatment process that minimizes distortion.
