The assortment of rolled metal from stainless steel grades is so diverse due to the widespread use of products from it (ready-made or blanks for further processing) in a variety of areas of production, construction and economic activities, which is classified using special voluminous technical reference books. You can get acquainted with it online using the catalog https://spec-metall.ru/ of the Alliance-Expert company, which supplies almost all categories of these products in industrial volumes from manufacturers.
Classification by alloy composition
A consumer who decides to purchase a certain type of stainless steel rolled metal should take into account that the material of their production is divided according to its composition, as a result of which:
- Products acquire certain parameters in terms of strength or elasticity.
- The final cost of production directly depends on the quality of the alloy.
The main parameter that is mandatory for any brand is the mandatory content of at least 10% chromium. At the same time, possible manifestations of corrosion are not completely eliminated, but it is so minimal that the use of stainless steel products is much more cost-effective in comparison with counterparts from non-ferrous metals. The main format for the classification of alloys today is as follows:
- Austenitic-ferritic or austenitic-martensitic - include up to 33% chromium and additionally nickel in their composition.
- Chromium or ferritic - more than 20% chromium and low (up to 0.15%) carbon makes them plastic with high resistance to chemically active substances.
- Martensitic and ferritic-martensitic contain up to 17% chromium, no more than 0.5% carbon, belong to the category of sufficiently strong materials.
You can get more detailed information on the technical parameters of rolled metal from stainless steel grades using the website of the official supplier. All products presented on the resource comply with GOST standards and have a manufacturer's quality guarantee.
