Product Description

Precision CNC turning steel parts 4130 steel parts for mechanical equipment

4130 structural steel has high strength and toughness, high hardenability, and the critical hardenable diameter in oil is 15-70mm; the hot strength of steel is also good, with sufficient high temperature strength below 500 ℃, but at 550 ℃ Its strength decreases significantly; when the alloying element is at the lower limit, the welding is quite good, but when it is close to the upper limit, the weldability is moderate, and it needs to be preheated to above 175 ℃ before welding; the machinability of the steel is good, and the plasticity is moderate during cold deformation; The range of 300 to 350°C has the first type of temper brittleness; there is a tendency to form white spots.

Application:

 This kind of steel is usually used in a quenched and tempered state, and when the carbon content is the lower limit, it can also be used as a carburized steel that requires higher core strength. In the medium-sized machinery manufacturing industry, it is mainly used to manufacture quenched and tempered parts with large cross-sections that work under high stress conditions, such as shafts, spindles, and high-load steering wheels, bolts, stud bolts, gears, etc.; in the chemical industry It is used to manufacture welded parts, welded structures composed of plates and pipes, and high-pressure conduits whose temperature does not exceed 250°C in a medium containing nitrogen and hydrogen; in the steam turbine and boiler manufacturing industries, it is used to manufacture fasteners that work below 450°C, Flanges and flange covers under high pressure below 500°C.
