Heat treatment method of A514GrB steel

A514GrB steel has a higher carbon content than low-carbon steel, and it is considered as low-alloy steel. It is not advisable to directly heat-treat A514GrB steel, because A514GrB steel can be soften when heated.

Now, we will briefly introduce the heat treatment methods of A514GrB from four aspects: normalizing, annealing, quenching and tempering.

·Normalizing
Normalizing is an important step of heat treatment.It can improve the strength and hardness of A514GrB steel to make it more suitable for the mechanical manufacturing industry.

·Annealing
Annealing is a common method of heat treatment that changes the properties of metals by heating and cooling. To avoid problems such as cracks in the A514GrB steel, it is necessary to control the rise and fall of temperature during the insulation and cooling process.

·Quenching
Quenching is a method of rapid cooling,It can further improve the hardness and toughness of A514GrB steel.

·Tempering
Tempering will reduce the hardness of A514GrB steel, but it can improve the toughness and plasticity of A514GrB steel.

All above are the main methods of A514GrB heat treatment, you can purchase A514GrB steel from BBN , we have a large number of A514GrB steel in stock to meet your delivery time requirements.
