Nickel - chromium - iron alloy 825 because of the alloy contains about 30% of the iron, so the alloy 825 is sometimes included in the Super Series austenite stainless steel. This kind of alloy and alloy 20, the main purpose of development for a variety of purposes of sulfur and phosphorus. Although the alloy 825 has a strong resistance to hydrochloric acid corrosion ability, but susceptible to chloride pitting and crevice corrosion, especially in solution does not flow, ventilation is not in. Alloy 825 with high iron content makes it a strong base and halogen corrosion resistance is lower than the alloy containing nickel higher. Jiangsu Juya special steel according to ASME standard and Realization of forging forging, punching, and can be based on ASTM, GB, HG, JB, DN and other national standard flange production 1/2-24 inch flange, pressure rating from 150 pounds to 2500 pounds of high level fresh butt welding, welding, blind plate, good welding, integral flanged, socket weld flange, threaded flange, loose flange, splay blind plate, etc. various kinds of special form of discharge ring flange. Our advantage: the company is equipped with 500KG vacuum smelting of 2000KG ESR ingot, and perennial with inventory, we can do the MOQ is one, because of steel ingot standby our fastest delivery time for a week of special alloy, favored by domestic and foreign customers
