DIN 17350 1.3255 Introduce

DIN 17350 1.3255 is a grade of steel that is widely used in industrial applications. Steel is an alloy made up of iron and other elements, and it is a handy material because it is strong and malleable. The type and amount of elements present in the steel determine the mechanical properties. DIN 17350 1.3255 steel is a high-grade cold-work steel, having outstanding mechanical properties and excellent machinability. It is used in tools, dies, and precision parts that require strength, good wear resistance, and high compressive strength at elevated temperatures.
