Aluminum Composite Panel Manufacturers introduced methods to improve the hardness of composite panels:

  1. The stainless steel clad plate generally cannot reach the hardening of the quenching treatment, but the surface hardening of the nitriding treatment can be used, but the depth is very limited.
  2. 304 austenitic stainless steel clad plates do not pass high-temperature heat treatment to increase the hardness. Generally, solid solution treatment is used to improve corrosion resistance and reduce hardness. Austenite has the following methods to increase hardness: QPQ treatment, high hardness, but black on the surface, no color difference, good corrosion resistance, high deformation, aging treatment, can be used basically on the basis of matrix 200 (HV ) According to the degree of deformation.
  3. Austenite is a solid solution of carbon dissolved in the Fe gap which is a commonly used symbol, A. It still maintains a gamma-iron face-centered cubic lattice. The capacity of soluble carbon is greater, the Omega C of carbon dissolved at 727°C is 0.77%, and that of soluble sugar is 2.11% at 1148°C. The austenitic stainless steel clad plate is a stable structure under a high temperature greater than 727℃. The austenite has good plasticity, which is required for most of the organization when steel is processed at high temperature and high pressure. There is no magnetic austenite.
  4. The stainless steel composite plate can be adjusted by heat treatment. Its mechanical properties are a kind of hardened stainless steel composite plate. Post-quenching has high hardness and different tempering temperature has strong toughness. It is mainly used for steam turbine blades, tableware, and surgical instruments. According to the difference in chemical composition, martensitic stainless steel clad plates can be divided into martensitic chromium steel and nickel-chromium martensitic steel. According to different structures and strengthening mechanisms, it can also be divided into martensitic stainless steel, martensite, and austenite (or half martensitic precipitation hardening stainless steel, and maraging stainless steel clad plate.

Through the above introduction, Aluminum Solid Panel Manufacturers hopes that you can simply refer to the content of this article in future use.
