Advantages and scope of stainless steel strips
Stainless steel strips are all-metal products without cavities inside. For their manufacture, corrosion-resistant, heat-resistant and heat-resistant alloys of various brands are taken. Rolled products are used in everyday life, in production as an independent part, a decorating material, a blank for creating tools, components of technical devices.
Regulatory framework
Production technology, assortment are regulated by regulatory documents:
- GOST 103-2006 for hot rolled long steel products;
- GOST 4405-75 for hot-rolled and forged tool steel strips.
The composition of stainless metal is determined by GOST 5632-2014.
Features
Stainless steel strips are produced by hot and cold rolling methods. There are three categories of products according to the accuracy of its compliance with the specified parameters, the quality level:
- elevated (A);
- high (B);
- normal (In).
The characteristics of rolled metal are also affected by the sickle shape — the degree of curvature. According to this parameter, it is allowed to belong to two classes: up to 0.2% and no more than 0.5% of the total length.
The properties of the product determines the composition of the alloy from which it is made.
- Chromium gives the steel anticorrosive properties, forming a self-healing protective layer of oxides on its surface. This film does not allow aggressive compounds to corrode the metal. For the production of strips intended for use in mildly aggressive environments, it is sufficient to use alloys with 12% of the element; grades with 17% are able to withstand nitric acid solutions with a strength of up to 50%.
- Nickel, molybdenum, and other alloying additives increase the viscosity and fatigue strength of steel, increase corrosion resistance.
The grade of the alloy determines the scope of the product. To buy stainless steel strips, contact the managers at the office of ALFA-STAR in St. Petersburg. They will advise you on the assortment, help you choose the materials you need.
