EN 10268 1.0574 Introduce
EN 10268 1.0574 is a high-strength steel developed in Europe. It is a cold drawn or cold rolled steel, with a higher strength than normal carbon steel. It is often used in automotive engineering, machinery and equipment production, construction elements, gearing production and power tools. EN 10268 1.0574 is produced in a wide range of shapes and sizes, allowing for the production of high-performance components. EN 10268 1.0574 is an alloy composed primarily of iron, with smaller amounts of carbon, manganese, silicon, phosphorus and sulfur. The carbon content is typically around 0.08-0.12 percent, with an allowance for controlled amounts of titanium, Vanadium and Niobium to produce five grades of different strength levels. The steel is also heat treated to increase its strength, often by hot rolling or normalizing.
Smelting temperature:1275°C - 1752°C
Application:High-strength cold-formed cold-rolled stainless steel flat products with high yield - Technical delivery conditions
