Product Introduction

Spring Steel Flat Bar 6150 1.8159 DIN 51CrV4 is an alloy spring steel. It has excellent mechanical properties and processing properties. It can also be called ISO 51CrV4 steel and 1.8159 steel. It has high hardenability, fatigue strength and yield strength. Adding vanadium to steel can make the crystals smaller, reduce overheating sensitivity, and improve the strength and toughness of the steel. But its weldability is not good. If you are interested in this, you can check the properties, chemical composition and heat treatment of 6150 round steel sheet as follows.

51CrV4 steel application

Due to its special properties, it is used in the aircraft industry, automobiles, ships, ships, metallurgy, chemical industry and other fields. As a ship material, it is usually used in low temperature conditions. Therefore, it must have excellent general mechanical properties at room temperature. The plasticity and impact toughness of steel are closely related to the microstructure. If the strength is increased, the plasticity and impact toughness of the steel will be reduced.

51CrV4 steel is a high content spring steel. It is a good material for high load, large cross section springs and valve springs.

It can also be used for the integral hardening of steel in plastic molds and die casting molds.

6150 steel round rod heat treatment

anneal

Annealing treatment can make it have good machinability. Austenitizing occurs at 1400ºF (760ºC) and then at 1250ºF (680ºC). Perform isothermal regression

normalization

The standard temperature for standardization is 1650ºF (900ºC). And then use the air cooling method.

indurate

Austenitize 6150 steel at 1550-1625ºF (845-885). The quenching method of oil is small, and the large is the use of water quenching.

temper

Depending on the required performance, start at 1000-1250ºF (540-680ºC).
