Why do foundries choose to use ASTM 1045 steel to produce large cast steel parts?

Steel types are numerous and complex. According to different classification methods, steel can be divided into many types; for example, based on chemical composition, steel can be divided into carbon steel and alloy steel.

Among the many types of steel, many foundries choose to use ASTM 1045 steel when producing large cast steel parts.

So, why do foundries select ASTM 1045 steel to produce large cast steel parts?

Here we will briefly introduce this ASTM 1045 steel.China's standard 1045 steel belongs to carbon structural steel and is one of the more frequently used steels by foundries in the processing of large castings.

Compared with other steels, 1045 steel has higher hardness than carburised quenching steel, minimal deformation after heat treatment, and can be widely used in cast steel processing.

The annealing and normalising treatment of 1045 steel is better than quenching and tempering, with high strength and good machinability.

Using 1045 steel to produce large cast steel parts can ensure the plasticity, toughness and wear resistance of the castings, improve the quality of the cast steel parts, provide good mechanical performance during subsequent use, thereby extending the service life of the cast steel parts and reducing the defect rate.
