What is the difference between alloy pipe?
The German steel number corresponding to the steel is D, the Japanese steel number is D.
Chemical composition of steel % element content.-. .-. . . .-. .-. .-. .-. .-. .-. .
Each alloying element in the steel pipe plays a role in solid solution strengthening, dispersion strengthening and improving the oxidation resistance and corrosion resistance of the steel. The detailed analysis is as follows.
Advantages of steel pipe:
① It has low thermal expansion coefficient and good thermal conductivity.
②The impact toughness and material brittle transition temperature are significantly better than similar steels.
③ It has high room temperature tensile strength up to 100% and good plasticity.
④ It has good bending performance of the whole pipe.
⑤ It has higher high-temperature durable strength and allowable stress. The high-temperature durable strength after operation at high temperature of ℃ is twice that of steel. The allowable stress in ~℃ is significantly higher than that of steel.
⑥The high-temperature fatigue performance is better than that of Japanese steel, and its high-temperature oxidation resistance is higher than that of steel.
