Product Description
DIN 34Cr4/1.7033 QT Alloy Structrural Steel
1: 34Cr4 Steel Introduction
34Cr4 and 34CrS4 are German DIN executive standard steel grades, belonging to alloy structural steel, medium carbon steel, which is easy to process. After heat treatment, it has certain toughness, plasticity, wear resistance and good comprehensive mechanical properties. It is generally used after quenching and tempering. 34Cr4 alloy structural steel has high yield strength, tensile strength, endurance strength, yield ratio (generally about 0.85) adequate plasticity and toughness.
