Product Description
DIN 34CrMoS4/1.7226 QT Alloy Structrural Steel
1: 34CrMoS4 Steel Introduction
34CrMoS4 is a heat treatable steel containing at least 0.9% Cr, 0.15% Mo as a reinforcing element, similar to 35CrMo in China. It has good repeated impact strength, fatigue performance under alternating bending stress, but poor weldability, so the steel grade can only be welded by appropriate steps. This material is usually used in quenched and tempered conditions.

7: 34CrMoS4 Steel Application
34CrMoS4 is widely used in the manufacture of various mechanical parts, such as bearings, gears, connecting rods and so on. Due to its good strength and toughness, this alloy steel can be used to manufacture load-bearing structures, such as large building bridges and high-rise buildings. It is also used in the manufacture of automotive parts, such as engine crankshafts, Celsius camshafts, suspension systems, etc.
