1: 28Cr4 steel introduction
28Cr4 is a german steel defined in DIN17200-84 standard. Compared with 30 # steel, 28Cr4 alloy structural steel has higher strength and hardenability. 28Cr4 steel is usually used in quenched and tempered state or after normalizing.

4: 28Cr4 steel mechanical properties
The mechanical properties mainly include tensile strength, yield strength, elongation, area or reduction, hardness, impact value, non-metalic inclusion etc. Different heat treatment, the mechanical properties will be different, such as normalized, tempered, QT. If you want to know the properties, kindly contact the salesman.
