Forgings are blanks for the manufacture of final metal parts using a certain technology and equipment. They can have different cross-sectional formats (rolled tubes) and geometric shapes (for example, square, circle). Almost all stainless steel forgings are manufactured at metallurgical enterprises in the following ways.
Stamping
Raw materials, heated to a plastic state, are placed in a special form and take on its geometric dimensions through the impact of shock (shock) loads. This technology belongs to the category of labor-intensive and costly, it requires compliance with precise temperature parameters and special high-tech equipment. The forgings made in this way are distinguished by:
- High dimensional accuracy.
- No surface defects.
- The uniformity of the metal structure.
Some types of soft and ductile alloys are cold formed without preheating the blanks. Cold and hot stamping provides a high speed of technological operations due to the fact that it allows you to form all sides of the product at once.
Forging technology
Shaping is carried out in stages using special presses and hammers that produce multiple shock loads on the surface of the workpiece. The technological process is quite long, and the final product does not have the required accuracy. In most cases, forging is carried out after the billet has been heated to a certain temperature to make it more plastic.
The listed options for the manufacture of forgings from stainless steel grades do not change the structure of the metal. It remains immune to corrosion and chemical reactive elements.
You can get more complete information on the types and classification of forgings using the official website of the Metallindustriya company, which supplies this type of rolled metal directly from the manufacturers' metallurgical enterprises. The entire assortment presented on the pages of the catalog meets the GOST parameters and is sold to customers on a contractual basis for deliveries.
