In the whole process of daily application of stainless steel pipes, in addition to the thickness, corrosion resistance, and length of the stainless steel pipe, everyone will be concerned. There is also the question of whether the stainless steel pipe has a steel stamp, which is usually a problem that many customers pay attention to. Let's talk about the basic knowledge of whether stainless steel pipes have steel seals.
The first stainless steel pipes are divided into three types according to different materials: 201, 304, and 316L. Among them, 201 stainless steel pipes and 304 stainless steel pipes are common. Generally, 201 stainless steel pipes below 0.9 solid thickness are generally stamped, 304 stainless steel pipes are generally all thin and thick are stamped, but why do 304 stainless steel pipes have steel stamps on the surface? This is because 304 stainless steel stamps are used to avoid sales in the market. Inferior stores have sales of 201 counterfeit 304 and have a 304 steel seal. Customers can visually and clearly understand whether the goods they buy are 304 stainless steel pipes.
I still remember that a customer of double-tube heating tube in Shaoxing City must have a batch of 304 stainless steel pipes. The customer here must make a batch of 304 stainless steel pipes. The surface of the stainless steel plate cannot have a steel stamp. Therefore, a batch of 304 stainless steel without steel stamp was ordered from the factory. Therefore, in the specific whole process, 304 can also choose to stamp or not stamp according to the difference of customer satisfaction, which can better meet the requirements of customers.
