Cutting processin
Quenching and Tempering Processing
Technology for heating processing
General steel heat treatment includes the following techniques:
Steel is heated to a temperature higher than its transformation point to form austenite; then the steel is quickly cooled to form martensite. This process increases the hardness and strength of the steel without changing its shape, but the steel becomes more brittle.
Heating the steel again after quenching adds elasticity and toughness, transforming the steel to a structure with high resistance to wear. However, the hardness is slightly reduced when compared with the state after quenching..
This process is used to improve the structure and soften the steel since semi-hard steel, hard steel and alloy steel are difficult to cut due to their hardness.
This process is used to make the structure finer, uniformize carbides and remove residual stresses, thus making the steel easier to cut. Since hardenability also improves, normalizing is sometimes used as a pre-process before quenching.

Inspection Machining
How do you test the composition of a metal? The two most common methods used to determine the chemical composition of an alloy (or any metal) are X-ray fluorescence spectroscopy (XRF) and optical emission spectroscopy (OES). XRF is non-destructive, however, OES is more sensitive than XRF to lighter elements.
In the steel export activities, we also need to pack the steel to prevent the steel from being scattered in the transportation process. In the hoisting process, it is necessary to lift the steel. So steel is very necessary in the export process. Below is the picture of packaging According to the requirements of the state of steel materials, the use of binding, bare, frame, pallet.
Packing standard: according to the following national standard requirements (the parts beyond the requirements will be specified separately)
