Fireproof Aluminum Composite Panel generally does not achieve hardening by quenching, but nitriding surface hardening can be used, but the depth is very limited.

410 martensite fireproof aluminum composite panels can be used in high temperature heat treatment to improve hardness and annealing treatment to reduce hardness. The first solid solution of the 17-4 precipitation hardening fireproof composite board can improve the aging hardness.


Austenite is a solution of carbon dissolved in gamma - a commonly used symbol of the Fe gap. It still maintains a gamma-iron face-centered cubic lattice. The soluble carbon capacity is larger, and the dissolved carbon at 727 ° C has an omega C = 0.77% and a soluble sugar at 1148 ° C 2.11%. Austenitic fireproof composite panels are stable under high temperature conditions above 727 °C. Austenitic plasticity is good, and steel is processed at high temperature and high pressure, which is required for most tissues. There is no magnetic austenite.
