1.4923/X22CrMoV12-1 stainless steel

Martensitic stainless steel, creep resisting steel/high temperature resistant steel, grade EN 1.4923 / DIN X22CrMoV12-1, hardened and tempered, Usual upper temperature limit for continuous operating at 580°C.

This grade combines the following characteristics:

• Moderate strength – 800 MPa UTS, 600 MPa 0.2% PS at room temperature
• Moderate high temperature strength – 280 MPa 0.2% PS at 550°C
• Good creep strength – 137 MPa rupture stress at 550°C  at 100000 hours
• Moderate toughness – typically 50 J at room temperature
• Basic corrosion resistance
• Weldable with care. Requires pre and post weld heat treatment

Components featuring elevated high-temperature strength for use in thermal engines and power plants, such as turbine blades, turbine discs, screws, bolts, pins and shafts.
