What is 20CrMoH alloy structural steel

20CrMoH steel is an alloy structural steel. H represents the steel with guaranteed hardenability, which means that when the material is subjected to end quenching test, the width of hardness band is relatively narrow and the hardness fluctuation is small. The hardness of the material is better controlled during quenching. It is mainly used to bear load or transfer work in the manufacture of automobile machinery. 20CrMoH executive technical standard: GB / T 5216.

20CrMoH alloy structural steel heat treatment and delivery status: hot rolling and annealing

20CrMoH alloy structural steel application:
20CrMoH steel is widely used in gears, shafts, chain rail links and other parts. 20CrMoH alloy steel is suitable for manufacturing medium and small module gears, shafts, etc. It can also be used for blades of steam turbines below medium pressure working at the pressure level of superheated steam area.

20CrMoH steel characteristics:
20CrMoH alloy structural steel is a widely used structural steel with stable smelting process, good hardenability, good carbonitriding process performance, small deformation after heat treatment, no tempering brittleness, and good processing and manufacturing performance and welding performance.
