X2CrNiMo18−4-3 (316L) is classified as a stainless corrosion resistant simple heat-resistant steel of austenitic class. X2CrNiMo18−4-3 steel is low-carbon version of steel AISI 316l. The letter L designates a part of carbon (0.03%) in composition. Due to this, it is better suited to manufacture of welded constructions.

Percentage composition GOST 5632−72

Fe Cr C Mn P Ni Mo Si S P
Basis 16,8 — 18,3 ≤ 0,03 1 — 2 ≤ 0,035 13,5,-15 2,2 — 2,8 ≤ 0,4 ≤ 0,02 ≤ 0,035

It is smelted in electric-arc furnaces. This grade complies with rigorous requirements of national standards. Manufacture is specified by following GOST: 25 054−81, 5632−72 and 5582−75, and such technical conditions as: 14−1-240−72; 14−1-1154−74; TC 14−1-692−73; 14−1-1183−74; 14−1-1541−75; 14−3-396−75;14−1-2132−77; 14−1-2144−77, 14−1-2134−77.


Temperature of hot working (rolling and forging) at the beginning is 1170 °C and 900 °C at the end. This steel can be satisfactorily cut. It has a good weldability by method of automatic and manual welding.


Manual electric-arc welding requires an application of electrodes of grade OZL-20, which have a wire core 03H17N14M2. The same wire is applied in atmosphere of shielding gas or at automatic welding under flux. Resistance of welding seams is the same as in the main metal. Welding seams have a corrosion rate of 0,041−0,11 mm/h in atmosphere of carbamide synthesis.

Flat products of X2CrNiMo18−4-3 grade are used in manufacture of welded equipment for extraction of phosphorus acids and similar compositions that are characterized by a high corrosive power. It has a high resistance to knife-line and intercrystalline corrosion. This allows using it in corrosive environments in temperature range of up to +80°С. X2CrNiMo18−4-3 grade is used in equipment that is intended for making of mineral fertilizers, welding wire, welding electrodes (for joint of nozzle parts, pipe joints, pipes with apparatus casing, repair of welding composition of tools that work in radioactive environment). X2CrNiMo18−4-3 steel is used as a means of clad layer of centrifugally cast pipes, for convective coils and two-layered hot-rolled corrosion-resistant sheets, installations for production of ethylene, ammonia, carbon disulfide, hydrogen and other chemical elements.
