Product brief introduction

Good process performance and welding performance, high durability at 500-550°C. When the temperature exceeds 550°C, the oxidation resistance deteriorates and the creep strength decreases significantly. When the temperature is in the range of 500 to 550 °C for a long time, the thermal strength of the steel decreases and the strength decreases. Used for manufacturing high temperature and medium pressure steam pipes at 510°C, headers and superheaters and forgings with a wall temperature of 550°C
