Heat -resistant steel.
Steel is called heat -resistant if it contains:
– chrominocyl alloys;
– alloys from chromium, nickel and manganese.
Such types of alloys are made by additional logging. The most common is a nickel -based steel. Such steel can be used within a temperature of 1100 – 1200 degrees Celsius. Due to such high temperatures, products of this type, can be used in the manufacture of aircraft, sea vessels, power plants, oil refining equipment, etc. D. On sale are only the most popular and demanded names of the assortment series. For example, a sheet of steel:.
12x1mf
Has a fairly wide range of use. But, at the same time, there is a limitation on the temperature regime 540 – 580 degrees. Also, high -temperature welding of steel is limited.
15x5m
Low -alloy steel. Thanks to this quality, products from it have a high level of oxidation resistance, and later to corrosion. It is optimal for the manufacture of valves, fasteners, pipes, etc. D. Today, is the most popular in use in production.
25x1mf
This type of steel is characterized by high heat resistance. Studs, bolts and many other fasteners are made from it.
