Heat treatment

The forming properties are better in the state, annealed and newly quenched state and the strengthening effect of heat treatment is significant, but the heat treatment process is strictly required. Corrosion resistance is poor, but can be effectively protected by pure aluminum cladding; easy to produce cracks when welding, but can be welded and riveted using special technology.
