Galvalumed sheet, with 55% aluminum zinc alloy coating on the surface. The surface of the Galvalumed sheet presents a unique smooth, flat and gorgeous star, and the basic color is silver white. The special coating structure makes it have excellent corrosion resistance. The normal service life of the Galvalumed sheet can reach 25a, and the heat resistance is very good, which can be used in the high temperature environment of 315 ℃; The coating has good adhesion with the paint film, has good processing performance, and can be punched, sheared, welded, etc; The surface conductivity is very good.
The 4130 carbon steel plate is usually used in the quenched and tempered state. When the carbon content is at the lower limit, the steel can also be used as the carburized steel with higher central strength.
Stainless steel is an alloy of Iron with a minimum of 10.5% Chromium. Chromium produces a thin layer of oxide on the surface of the steel known as the passive layer. This prevents any further corrosion of the surface. Increasing the amount of Chromium gives an increased resistance to corrosion.
304L stainless steel is mainly used in automobile accessories, hardware tools, tableware, cabinets, medical appliances, office equipment, weaving, handicrafts, petroleum, electronics, chemicals, textile, food, machinery, construction, nuclear power, aerospace, military and other industries.
