Product Description
DIN 17200 50CrMo4/1.7228 QT Alloy Steel Bar
1: 50CrMo4 Steel Introduction
50CrMo4 steel is a Cr-Mo series alloy structural steel with medium carbon. It's a European steel grade from EN 10083-1. With high fatigue strength, excellent hardenability, good toughness and high tempering resistance, 50CrMo4 is widely used in highly stressed components, such as heavy-duty shafts, gears, spindles, connecting rods, and high-strength fasteners. 50CrMo4 is generally supplied in quenched and tempered condition with a typical hardness range of 28-34HRC.
