stainless steel insect mesh

5, the guardrail cavity is equipped with galvanized steel lining or aluminum alloy to strengthen, with enough strength and impact resistance, so that the guardrail has the strength and beauty of steel. Stainless steel welding mesh can be used in the construction industry, highway, bridge for reinforcement. Used for mechanical protection, industry, agriculture, construction and so on.

The coating of electrode plays a very important role in the welding process. If adopting the light of the coated electrode welding, is in the process of welding, oxygen and nitrogen in the air can invade the molten metal, the metal iron and beneficial elements carbon, silicon, manganese oxide and nitride oxide and nitride formation, and remain in the weld, weld slag or crack. And melt into the molten pool in the gas can make the weld produces a large number of pores, these factors can make the mechanical properties of the weld is greatly reduced, at the same time to make the weld brittle.

For example, in gray iron, its carbon exists in iron ore in the form of graphite, the crack is often gray, soft and tough, simple filter cutting, suitable for casting. In the white iron, the carbon and iron are combined to form iron carbide, the crack appears white, the quality is very strong and brittle, and it is the material of malleable steel. Alloying grade is composed of various alloying elements with different composition and structure.
