What is Alloy 625 plate?
Alloy 625 plates are manufactured strictly according to ASTM B443/ASME SB443 standards, exhibiting exceptional performance in extreme environments. They have a tensile strength of ≥ 827 MPa, a 0.2% yield strength of ≥ 414 MPa, and a maximum operating temperature of up to 982°C (1800°F). These plates offer excellent resistance to chloride pitting, crevice corrosion, and stress corrosion cracking, as well as superior fatigue and thermal fatigue strength, making them ideal for high-pressure, high-temperature, and corrosive environment applications.
Which industries commonly use Alloy 625 plates?
Offshore platforms & subsea equipment
Heat exchangers and pressure vessels
Chemical processing reactors
Aerospace structural components
Marine exhaust and flue gas systems

Can Alloy 625 plate be welded without post-weld heat treatment?
Yes, Alloy 625 plate generally does not require post-weld heat treatment (PWHT) to maintain its excellent corrosion resistance or strength because it's a solid-solution alloy, meaning its properties come from its composition, not precipitation hardening. However, PWHT might be considered for specific severe service conditions, like preventing stress corrosion cracking (SCC) in caustic soda, or for dimensional stability in complex parts, but standard welding procedures are fine for most applications.
What is the current Alloy 625 plate price per kg?
As of December 2025, the price of Alloy 625 (UNS N06625) plates ranges from RMB 365–598/kg domestically (RMB 365/kg for orders ≥500 kg, RMB 380–420/kg for 100–499 kg, RMB 598/kg for small batches ≤10 kg) and US$10.50–56/kg for FOB export, with hot-rolled plates generally 15%–25% cheaper than cold-rolled ones.
