Factors that Affact the Hardness of Stainless Steel Seamless Pipes

There are many types of stainless steel pipes in the market, and the prices are different. We must consider all factors and choose high-quality products when purchase. Generally, the quality of the stainless steel electric heating pipe can be judged from the nickel content. The high quality stainless steel pipe are corrosion resistance and high temperature. So what affact the hardness of stainless steel pipe?

1. The problem of the annealing of the steel strip in production. The quality of the steel strip annealing treatment is directly effect the hardness of the stainless steel seamless pipe. Whether it is 201 or 304 stainless steel seamless pipes, there are corresponding standards for their hardness. 

2. The carbon content of stainless steel seamless pipes. The main function of carbon in stainless steel seamless pipes is to increase the hardness of the pipes, but carbon is also an impurity in stainless steel. The more the content, the harder the pipes will rust. Will also increase. And, poor quality stainless steel seamless pipes are prone to folds. we can take a look at the surface of the stainless steel pipe to see if there are fold lines. The reason for the fold lines is because the manufacturer pursues high efficiency, leading to deviations during rolling, which affact the hardness of steel pipe.
