ASME SA209 Seamless T1a Carbon Alloy Steel Boiler Tubes
YUHONG Group offers ASME SA209 T1a SMLS carbon Alloy steel tubes which generally are used for heat exchanger and boilers.
This specification covers several grades of minimum-wall thickness, seamless, carbon-molybdenum alloy-steel, boiler and superheater tubes.
Its chemical composition is simple, but it contains molybdenum, so its thermal strength is better than that of carbon steel while maintaining the same process performance as carbon steel. However, the steel also has a graphitization tendency after long-term operation at high temperature, so its service temperature should be controlled below 510°C and overheating should be prevented.
During smelting, the addition of Al should be limited to control and delay its graphitization process. This steel pipe is mainly used for parts such as water wall, superheater and reheater.
