DIN 17175 الصف 15Mo3 أنبوب التخفيف

DIN 17175 is the specification for a heat-resisting seamless steel tube. Grade 15Mo3 alloy steel pipe is commonly used for heating surface pipes of low and medium pressure boilers. 15Mo3 steel pipe is used for the heating surface tube, economizer, superheater and reheater of the high-pressure boiler (working pressure is generally above 9.8Mpa and the working temperature is between 450℃ and 650℃).
