In general, even for seamless steel pipe, we can make a list for different types of them due to wispy difference by different production process, adding original materials. Today, our main topic would be a special seamless steel pipe-bearing steel pipe. The meaning of bearing is having a/some/no etc bearing on sth. According to the definition, we would know that as for bearing steel pipe, it has high smelting quality requirements, meanwhile, and requires strict control of sulfur, phosphorus, hydrogen content. Only this, can it does its immense pressure and friction job perfectly. What exact characters it should have? Steel hardness, wearing resistance, high elastic limit would be our consideration if we need to produce bearing steel pipe. So if you need seamless steel pipe and you donâ??t know which one to choose, welcome to have a discussion with us.
