Hangzhou precision parts processing manufacturers for you to introduce the features and applications of common metals in 10 kinds of machining:

1, 45— — high quality carbon structural steel is the most commonly used medium carbon quenched and tempered steel. The most commonly used medium carbon quenched and tempered steel has good comprehensive mechanical properties, low hardenability, and easy to crack when water quenched. Small parts should be treated with quenching and tempering, and large parts should be treated with normalizing. It is mainly used for manufacturing high strength moving parts, such as turbine impeller and compressor piston. Shaft, gear, rack, worm and so on. The welds should be preheated before welding, and stress relieving after welding. 2, Q235A (A3 steel) — — the most commonly used carbon structural steel. It has high plasticity, toughness and welding properties, cold stamping properties, and certain strength and good cold bending properties. Widely used in general requirements of parts and welding structure. Such as less tensile rod, connecting rod, pin, shaft, screw, nut, ring, bracket, frame, building structure, bridge and so on.
