Brightness level of stainless steel after polishing: According to visual inspection, the brightness of the surface of polished parts is divided into 5 levels:

Heat treatment process generally includes heating, heat preservation, cooling three processes, sometimes only heating and cooling two processes.These processes are interconnected and uninterruptible.

Forging performance is the ability of metal materials to withstand plastic deformation without breaking during forging. It mainly depends on the plasticity of the metal. The better the plasticity, the better the forgeability of the metal. All kinds of steel and most non-ferrous metals and alloys have certain plasticity, so they can be forged in hot or cold state. After the metal material is forged, the internal pores can be welded, the fine shrinkage cavities can be dispersed and compacted, and the density of the metal can be increased; the columnar crystals and coarse grains in the cast state can be crushed into fine grains, and the hardness of the metal can be improved. mechanical properties.
