Common Machining Steel Material and Characteristics
2018-07-03 11:07:22

During processing the workpiece, the choice of metal materials often has an effect on the results of finished products. Therefore, it is necessary to understand some common metal materials and their characteristics. Here we introduce some steel materials commonly used in production.


Steel materials commonly used are the following:


45 steel

It is one of the most commonly used material in China. It’s a high quality carbon structural steel. 45 steel has good mechanical properties, high strength and good for machining and cutting . Generally it needs quenched and tempered when processing small parts, and normalized for large pieces. Main application for 45 steel is high strength moving parts, for example gears, rack and so on. Welding parts need to pay attention to the preheating before welding, after welding should pay attention to stress relief annealing.


Q235 steel

It is a widely used carbon structural steel. 235 means the yield strength value of this material. It not only good at its plasticity, toughness and weld-ability, but also has the characteristics of cold stamping. This steel is widely used in the general requirements of the parts and welding structures. For example, less stressed rod, connecting rod, pin, shaft, screws, nuts and so on.


40Cr

40Cr is one of the material widely used in mechanical manufacturing. It is alloy steel. The main feature of this steel is that after quenched and tempered, it has a good overall mechanical properties, good harden-ability. When oil cooling, it can reach high fatigue strength. When water cooling, the parts will appear complex shape cracks. Except for thermal treatment, 40Cr can also apply to cyaniding and high frequency quenching.


HT150 grey cast iron

This material is mainly used with the gear box, machine tool bed, hydraulic cylinder, pump body, flywheel,valve and other places.
