310s stainless steel pipe is a kind of steel with good corrosion resistance, as a widely used steel, 310s stainless steel seamless steel pipe has been applied in all walks of life. 310s stainless steel seamless pipe as an important material in industrial production, its performance directly affects the quality and efficiency of production. Therefore, it is very necessary to study the performance of 310s stainless steel pipe.
This paper mainly introduces the physical, chemical and mechanical characteristics of 310s stainless steel pipe and its use under different conditions.
I. Overview:
