DAIKOWT 2CrMoS
GTAW
- CREEP RESISTING STEELS
2Cr1Mo
Description
Rod for 2¼% Cr-1% Mo steel resistant to creep
Rod characterized by a high content of silicon and manganese, designed to enhance weldability and weld metal quality. Developed for prolonged service at high temperatures up to about 600 °C, it is suitable for steam power plants (pipelines, valve bodies, turbine castings, boiler superheaters). It ensures corrosion resistance from sulfur-containing crude oil (250–450 °C) and excellent performance against hydrogen attack in chemical and petrochemical plants, such as hydrocrackers, coal liquefaction plants, and pressure vessels for ammonia (NH₃) up to 450 °C.
