DAIKOWT 2CrMo
GTAW
- CREEP RESISTING STEELS
2Cr1Mo
Description
Rod for 2¼% Cr-1% Mo steel resistant to creep
Rod developed to ensure continuous service at high temperatures up to about 600 °C, specifically for use in steam generation power plants. Ideal for welding pipes, valve bodies, turbine castings, and boiler superheaters, it also offers excellent resistance to corrosion in the presence of sulfur-containing crude oil in the range of 250–450 °C. Used in chemical and petrochemical industries, it guarantees high performance against hydrogen attack, being employed in hydrocrackers, coal liquefaction plants, and ammonia (NH₃) pressure vessels up to 450 °C.
