Abstract
Procedure for the manufacture of steel straps; cold rolled of reduced thickness and free of longitudinal grooves, based on chromed stainless steel and air-hardening that still has austenite contents of 10 - 40% characterized in that a steel with 0.12% max. carbon, 13-23% chromium, 0 - 2% molybdenum, 0 -0.50% nickel, 1.0% max. silicon, 0.35% max. manganese, 0.010% max. sulfur, 0.025 - 0.060% phosphorus, 0.020 - 0.060% arsenic, but with at least 0.050% (arsenic + phosphorus), preferably 0.060% (arsenic + phosphorus) iron residue, eventually mixed with other impurity streams is cooled, as a roof from the heat of casting or as a roughing from the heat of hot forming, up to temperatures of approximately 750% and held there for 2 to 10 hours, then heating, eventually after intermediate cooling, to a temperature suitable for hot rolling of just below Ac1 (800 to 950ºC) and rolling to thickness for hot rolled strip.
