Main features: compared with 12 crmov steel, the steel has higher strong oxidation resistance and heat resistance.This steel creep limit and lasting value is very close, and in the case of persistent stretching with high plasticity;Technology of steel with good weldability, but before welding, need to preheat to 300 ℃, need in addition to the stress after welding processing.Is high pressure, superhigh pressure, subcritical boiler superheater, header, and the main steam pipe widely used types of steel.580 ℃ still has high heat intensity and antioxidant properties, and have higher durable plastic.Production process is relatively simple, the welding performance is good, but is more sensitive fire cooling speed.580 ℃ long-term use can produce pearlite spheroidization.The biggest advantage is that can be 100% recovery, accord with environmental protection, energy saving, saving resource of national strategy, the home policy encouraged to expand application field of 12 cr1mov alloy steel pipe.
At present our country 12 cr1mov alloy steel consumption accounted for the proportion of total steel is only half of the developed countries, 12 cr1mov alloy steel pipe using field provide a broader space for the development of industry.According to the Chinese special steel association 12 cr1mov alloy steel pipe branch of study, the future of our country high demand grew by an average of 12 cr1mov steel tube material can be up to 10-12%.
