Product Introduction

42CrMo4 1.7225 equivalent steel grades

42CrMo4 is a European standard high-strength alloy structural steel commonly used in the manufacture of various mechanical parts, gears, bearings, connecting rods and other engineering components. Belongs to one of the common international steel standards, DIN standard number is DIN EN 10083-3, no special requirements of the domestic alternative standard :42CrMo GB/T 3077. 42CrMo4 steel is often used in applications that require high strength, hardness and wear resistance, such as the manufacture of mechanical parts, gears, bearings, automotive parts, forging molds and other engineering components. Among them, excellent mechanical properties can be obtained after heat treatment, so it is widely used in engineering fields, especially parts that need to withstand high stresses and important loads.

The advantages of this steel are mainly reflected in these aspects:

high strength and hardness: 42CrMo4 steel has excellent strength and hardness after heat treatment, so it is very suitable for manufacturing parts that need to withstand high stresses and loads. This steel is heat treated during quenching and tempering to obtain the desired mechanical properties.
Wear resistance: 42CrMo4 steel has excellent wear resistance due to its alloy composition, especially vanadium and molybdenum. Suitable for manufacturing components that need to resist wear and friction, such as gears and bearings.
Corrosion resistance: The alloy composition containing chromium improves the corrosion resistance of this steel and can be used in wet or corrosive environments.
