SAE1045 Steel Round Bar 90MM

Decho is a professional supplier on SAE1045 Steel Round Bar 90MM

This steel is better on cold plasticity ,generally Annealing and normalizing are slightly better than quenching and tempering. It has higher strength and better machinability. After proper heat treatment, certain toughness, plasticity and wear resistance can be obtained. It is Suitable for hydrogen welding and argon arc welding, but not suitable for gas welding. Preheat before welding and stress relief annealing after welding.

SAE1045 Steel Round Bar 90MM

SAE1045 Material Description :

This steel is one of the most widely used steels in machinery manufacturing.

Recommended heat treatment temperature: normalizing 850, quenching 840, tempering 600.

1. The hardness of SAE1045 steel is higher than HRC55 (up to HRC62) after quenching without tempering.

The highest hardness in practical application is HRC55 (high-frequency quenching HRC58).

2. Do not use the heat treatment process of carburizing and quenching for SAE1045 steel.
