The basic qualities

The main performance parameters of the material are directly dependent on its quantitative and qualitative composition. The high content of corrosion-resistant heat-resisting alloy of the martensitic class 40X13 (4Х13) of carbon and chromium causes the high hardness, wear resistance, the elasticity of the material. Chrome gives the alloy resistance to corrosive destruction. It forms on the surface of semi-durable protective oxide film that protects the product from corrosion, and additional alloying ensures the stability of working characteristics of raw materials and increases its resistance. High iron content significantly reduces the alloy. The disadvantage is poor weldability.


Percentage composition according to GOST 5632−72 and 10543−98

Alloy C Si   Ti Cr Mn P S Ni Fe
40X13 0,35−0,44 ≤0,6 --- 12−14 ≤0,8 ≤0,03 ≤0,03 ≤0,6 basis

The alloy is melted in open electric arc or induction furnaces. Semi-finished products are produced according to the following GOST: 1133−71, 18143−72, 18907−73, 5582−75, 5949−75, 4405−75, 7417−75, 8559−75, 8560−78, 14955−77, 2590−2006, 2591−2006. And according to the following: 14−1-2186−7 and 14−11−245−88.


Steel 40X13 is used for products of high elastic springs, springs, bearings, working at t° to 450 °C, compressor components, operating in a slightly aggressive environment, measuring tools, knives, household items.
