| description | Gun barrel of firearms, preferably lightweight small guns formed from a deformed material with a chemical composition comprising carbon (0.28-0.36 wt.%), silicon (0.08-0.26 wt.%), manganese (0.15-0.35 wt.%), phosphorus (0.005 wt.%), sulfur (0.002 wt.%), chromium (3.6-4.4 wt.%), nickel (less than 0.5 (preferably 0.18) wt.%), vanadium (0.42-0.5 wt.%), tungsten (0.15 wt.%), titanium (0.08 wt.%), mixture of arsenic, tin and antimony (0.007 wt.%), iron (balance amount) and impurities due to smelting, is claimed, where the material has a hardness of at least 46-48 HRC. An independent claim is included for producing Gun barrel of firearms comprising performing a thermal compensation as a vacuum heat treatment, performing minimum of at least once hardening at a temperature of greater than 940[deg] C, preferably >= 995[deg] C with a holding time at hardening temperature after a partial warming of at least 20 minutes and performing at least twice tempering of hardness microstructure at a temperature of greater than 575[deg] C. |
