Product Introduction

42CrMo4 High Grade Molybdenum Alloy steel

42CrMo4 steel plate some common heat treatment processes:

Normalizing: The steel plate is heated to 850-900°C and then cooled in the air.

Annealing: The steel plate is heated to 800-850°C and then slowly cooled in the furnace.

Quenching: The steel plate is heated to 850-900°C and then quickly cooled in water or oil.

Tempering: The quenched steel plate is heated to 500-650°C and then cooled in air or oil.

It should be noted that different heat treatment processes will have different effects on the mechanical properties of the steel plate, so it is necessary to choose the heat treatment process according to the specific application scenario and requirements. At the same time, it is necessary to strictly control the heating temperature, holding time and cooling speed during heat treatment to ensure that the performance of the steel plate meets the requirements.
