Alloy Steel 56NiCrMoV7 Hot Rolled Steel Round

Alloy Steel 56NiCrMoV7 Hot Rolled Steel Round

1: 56NiCrMoV7 Steel Introduction

56NiCrMoV7 is a German DIN standard tool steel, which possesses good hardenability, toughness, heat resistance, polishability and is suitable for cold work tool steel and surface treatment. At the same time, it is a versatile tool steel with high strength, wear resistance, excellent cutting and machining properties, and good heat treatability.56NiCrMoV7 has excellent strength and is able to withstand high pressures and heavy-duty working environments. It not only has high strength, but also has good toughness and can maintain stability under high stress conditions.

13: 56NiCrMoV7 Steel Heat Treatment

Forging

Refinement of the grain size of steel by forging to improve its plasticity and toughness.

Soft Annealing

Soft annealing is to reduce the hardness of steel and improve its machinability.

Hardening

By quenching treatment, i.e., oil quenching, air quenching or vacuum quenching at 880-900°C, to increase the strength and hardness of steel. This step is an important part of increasing the hardness and strength of steel.

Tempering

Tempering is done to further increase the toughness and fatigue resistance of the steel. Tempering is carried out according to the required hardness and toughness, usually in the temperature range of 200-650°C. Tempering is the final step of the heat treatment process and is designed to optimize the properties of the steel so that in practical applications it better durability and reliability in practical applications.
