Introduction
X12CrMo5 Alloy Steel Plate is a high-strength chromium-molybdenum steel designed for high-temperature and high-pressure applications. It maintains mechanical stability and oxidation resistance in demanding environments.
Advantage
High Temperature Resistance - Chromium and molybdenum provide excellent creep and oxidation resistance up to 600 °C.
Strong Mechanical Performance - Maintains 440–590 MPa tensile strength and dimensional stability under heat and pressure.
Reliable Surface Quality - Smooth, even surfaces suitable for coating, painting, or further machining.
