Domestic and imported stainless steel equally have similarities and differences. The main determining factor when choosing a stainless steel is its marking. It is different in each country, therefore, in order to somehow facilitate metal identification, manufacturers use generally accepted systems, such as: AISI, SAE or AWS. The standards are widely used around the world and greatly simplify the choice of rolled metal buyers.
So what's the difference?
Thanks to generally accepted standards, the quality composition of stainless steels from manufacturers in different countries is similar. But there are still some differences. Yes, the composition may be the same, but sometimes there is an excess of carbon content by about 1%. Such a picture can be observed with all domestic brands and analogues, which are labeled in accordance with the generally accepted system.
For example, aisi stainless pipe contains its composition of parts of chromium and nickel, which increase the strength of the product. In the production of steels of various types, Western manufacturers subject billets to less hot treatment than domestic ones. As you know, under the influence of high temperatures, chromium burns out. As a result, the corrosion resistance of the stainless steel pipe is somewhat reduced.
As you can see, the difference between Chinese and Russian stainless steel is quite relative. Therefore, when choosing a stainless steel pipe, the price is not the last thing. Good metal rolling cannot be cheap. Accordingly, when buying rolled metal, you should pay attention to the marking, which determines the special resistance of products to various factors.
