12KhM Russian Low Alloy Steel Plate, 12ХМ Low Alloy High Temperature Steel Plate, 12ХМ Chemical Comp

12KhM is a Russian low-alloy steel plate, which implements GOST 5520-79 standard

12KhM steel plate fixed rolling: Wugang Xiangyang

is produced by scrapp process according to GOST 5520-79, and the mass fraction of copper should not exceed 0.3%.

GOST 19903-74 Alloy Plate refers to a metal plate. There are no restrictions on use in a variety of fields. This material is found in the automotive, chemical and shipbuilding industries.

There are different grades of alloy plates:

low alloy: 09G2S, 14HGS, 17GS, 16GS, 10G2S1, 17G1S;

Carbon: 15K, 16K, 17K, 18K, 20K, 22K;

Alloys: 10X2M, 12XM, 12X1MF.

12KhM heat resistance is the ability of steel to work under high temperature stress without obvious permanent deformation and failure. The main properties of heat resistance are creep and long-term strength.

Advantages and disadvantages

of 12KhM The advantage of this material is that after a long service life, the characteristics do not change. In addition, it is resistant to corrosion due to the chromium content (these are high temperatures). In addition, the product is low cost due to the components included in it.

Let's move on to the disadvantages: pitting corrosion occurs if the metal is in frequent contact with acids and salts. If the alloys are used for saws, knives, woodworking knives, then the blades may become dull if they are used for other purposes.
