Cr5Mo1V Tool Steel

Cr5Mo1V Introduction

Cr5Mo1V is an air quenching die steel with deep air hardening properties, which is extremely useful for complex dies where the shape must be maintained after quenching and tempering.

The deformation of this steel due to air quenching is about 1/4 of that of oil-quenched tool steels containing manganese series, and its wear resistance is between manganese type and high carbon and high chromium type tool steels, and its toughness is better than any other kind.

It is especially suitable for tools requiring good wear resistance and special toughness, and is widely used in blanking die and forming die roll punchesCalendering die and wire rolling die are also used in some types of scissors cold work die steels.

A2 steel is imported from the United States. It is one of the most widely used in class A air quenching steel, which is suitable for cold work die steels that require both wear resistance and toughness.

The steel is imported from the United States, with good air quenching performance, small deformation of air quenching size, uniform distribution of carbides, a certain impact toughness and good wear resistance.

The steel has good hardenability, which is extremely useful for complex molds where the shape must be maintained after hardening and tempering. The deformation of this steel due to air quenching is only 1/4 of that of oil-quenched tool steels containing manganese, and its endurance is between manganese type and high carbon and high chromium type tool steels. The toughness of this steel is superior to 9Mn2V and Cr12.

The spheroidizing annealing temperature of the steel ranges from 820°C to 860°C. The quenching temperature can not exceed 950°C while ensuring that more carbon and alloying elements are dissolved in austenite. The quenching cooling method should adopt oil cooling.
