lobster trapcorrosion resistant material introduction
Show damage lobster trapequipment manufacture process, defects and some effects of surface material, such as: dust, floating powder or embedded iron, heat back to the fire and other oxidation layer, grinding burrs, rust, welding arc spot, welding spatter, welding flux, welding defects, residual oil and grease, paint, adhesive and chalk and markers printing etc.. The vast majority are because of neglect of the harmful effects of them and ignore or do not. However, they are potentially dangerous to the protective oxide film. Protective film once damaged, be reduced to change thin or otherwise made, the lobster trapwill begin to corrosion. Corrosion is not generally throughout the entire surface, but the defects in or around the. This usually localized corrosion pitting or crevice corrosion, these two kinds of corrosion will develop in breadth and depth, and most of the surface is not affected by erosion.
304 stainless steel:
0Cr18Ni9, as a heat resisting stainless steel, widely used in food equipment, general chemical equipment, lobster trapscreen, atomic energy industry, lobster trapwire mesh is mainly used in filtration, chemical, mine etc..
A high alloy steel against corrosion in air or chemical corrosion, lobster trapis a beautiful surface and corrosion resistant performance is good, do not have to go through surface treatment such as plating color, and play the lobster trapinherent surface properties, a used in many aspects of steel, often called stainless steel. Represents the properties of 13 steel, chromium nickel steel and high alloy steel 18-8.
From the analysis of metallography, because lobster trapcontaining chromium and chromium film formed on the surface of thin film, the separated invasion and steel in oxygen corrosion effect. In order to maintain the natural corrosion resistance of stainless steel, steel must contain at least 12% chromium.
304 lobster trapis one kind of universal, which is widely used in production requirements of good comprehensive performance (corrosion resistance and moldability) equipment and parts.
304 lobster trapis in accordance with a brand USA ASTM standard production of stainless steel; equivalent to 304 of China's 0Cr19Ni9 (0Cr18Ni9) stainless steel. 304 19% chromium, 9% nickel.
304 is the most widely used stainless steel, heat-resistant steel. Used in food production equipment, chemical equipment, such as nuclear power in general.

321 stainless steel:
Alloy 321 (UNS S32100) is the stable performance of the stainless steel. Its main advantage lies in the temperature of 800-15000F (427-8160C) has the properties of intergranular corrosion resistance of strong carbide precipitation. Ti 321 lobster trapalloy chromium carbide in the structure's ability to resist more stable.
321 lobster trapalloys due to their excellent mechanical properties, work in a high temperature environment have the advantage. Compared with 304 alloy, 321 alloy lobster traphas better ductility and stress crack resistance capacity. In addition, 304L also can be used for anti allergy effect and intergranular corrosion.
Higher carbon content 321H can also, this class is UNS S32109
The titanium content standard of not less than 5 times the amount of carbon, and no more than 0.70%.
