Product Description
DIN 28Mn6/1.1170 QT Alloy Structrural Steel
1: 28Mn6 Steel Introduction
28Mn6 steel has high hardenability and small quenching deformation, but it has overheat, decarburization sensitivity and temper brittleness. Its plasticity during cold deformation is medium, machinability and weldability are acceptable, but the material needs to be preheated to above 200℃ before welding. After quenching and tempering, 28Mn6 steel has high strength, toughness and wear resistance, good static strength and fatigue strength.

7: 28Mn6 Steel Application
28Mn6 is commonly used as an important fastener of small section, as well as frame beam, gearbox gear, shaft, cold heading bolt and quenching and tempering parts of large section. In addition, 28Mn6 steel can also be used as carburized steel to make carburized parts with higher requirements for core strength, such as rear axle and journal of mine crane.
