Classification of SA210C steel pipes and their advantages

According to the current domestic production of SA210C steel pipe. Can be roughly divided into:hot-rolled seamless steel pipe, cold-rolled seamless steel pipe and precision seamless steel pipe. Overall:the advantages of seamless steel pipe are high pressure resistance, good toughness, long pipe section and few interfaces. Cold-rolled nitriding treatment of seamless steel pipeMay 12, 2021 · For seamless steel tube cold rolling, the martensite is changed to seamless steel tube before the rolled piece enters the precision extruder. The rough rolling is still carried out under the condition of full martensite, and then according to the ultra-rapid refrigeration system between the fine extruder and the rough extruder, the temperature of the hot rolled strip is reduced to change
