One of the more commonly used materials in sheet metal shell processing technology is galvanized steel, or SECC for short, which is actually a general cold rolled steel coil that is transformed into a galvanized product after degreasing, pickling, plating and various post-treatment processes in successive galvanized production lines.
Weldability: Many sheet metal parts are welded together by spot welding, oxy-fuel welding, arc welding or gas shield welding, so sheet metal parts are required to have weldability. This is especially important in excavation and repair. A material with good weldability has little tendency to weld and crack.
Very good plasticity: to have the ability to deform under the action of external forces without being damaged, on the cold parts, to have cold plasticity, such as car parts stamping parts, on the hot parts, to have thermoplastic, such as hot forgings taut spring steel, hot rivets rivets, etc..
Chemical stability: Many sheet metal parts are mostly operated in the open air, often touching with water and steam, especially like muffler, often working under the better temperature and corrosive gas. This requires sheet metal parts need to have chemical stability, both in the normal temperature corrosion, rust resistance is good, but also require high temperature or sun exposure is not corroded, not deformed.
Not too expensive, economical and practical: Regarding any component of sheet metal, economics should be taken into consideration as long as the operating conditions are met. If ferrous metal can be used, non-ferrous metal is not necessary; if non-ferrous metal can be used, precious metal is not necessary.
