Product Description
DIN 17200 34CrMo4/1.7220 Quenching and Tempering Steel
1: 34CrMo4 Steel Introduction
34CrMo4 is a Cr-Mo series alloy structural steel with medium carbon content. It is a European steel grade according to EN 10083-3. With high strength, good hardenability, good toughness, and low deformation during heat treatment, 34CrMo4 is widely used in the manufacture of various mechanical components such as shafts, bolts, gears, connecting rods, and high-pressure vessels. This material is typically supplied in a quenched and tempered condition, with a common hardness range of 28–32 HRC.
