310s/X8CrNi25-21/1.4841 Stainless Steel Pipe Fittings 2" SCH40s sandblast suface
"zheheng steel" produces and supply 310s/X8CrNi25-21/1.4841 Stainless Steel Pipe Fittings., Non-standard pipe fittings are also produced according to customer requirements. The company strictly implements ASTM B16.9 / B16.5,ASTM A403 SH3408, SH3409, DIN2605, EN10253, BS1965, JISB2312 and other standards for production.
310S (0Cr25Ni20) is an austenitic chromium-nickel stainless steel with good oxidation resistance and corrosion resistance. Because of the higher percentage of chromium and nickel, 310S has much better creep strength and can continue to operate at high temperatures High temperature resistance.

310S stainless steel is austenitic chromium nickel stainless steel, which has good oxidation resistance and corrosion resistance of 310S stainless steel. Because a higher percentage of chromium and nickel, it has much better creep strength and can continue to operate at high temperatures. Good high temperature resistance. Due to the high content of nickel (Ni) and chromium (Cr), it has good oxidation resistance, corrosion resistance, acid and alkali resistance, and high temperature resistance. The high temperature resistant steel pipe is specially used for the manufacture of electric furnace tubes, etc. After the content, due to its solid solution strengthening effect, the strength is improved. The chemical composition of austenitic stainless steel is based on chromium and nickel. Elements such as molybdenum, tungsten, niobium and titanium are added. Therefore, it has high strength and creep strength at high temperature. Melting point is 1470 ℃, softening at 800 ℃, allowable stress continues to decrease.

Why choose us:
1. All pipe fittings are strictly implemented in accordance with the standards, accept any third-party inspection, and return service.
2. Before leaving the factory, 100% dimensional inspection, 100% spectral test, mechanical and mechanical performance test, pickling, pickling process are mainly aimed at the removal of surface grease and harmful substances, complete surface passivation to prevent oxidation. Some suppliers have not implemented ( Because the surface is not visible to the naked eye after sandblasting) annealing and solid solution (heat treatment), many goods on the market are not heat-treated. When the pipe fittings are in some cold or hot environments, the seam will slowly crack if it is not heat-treated. This process is invisible to the naked eye, surface sanding (many relatively inexpensive processes on the market), bevel ends, etc.
3. Normally, the individual weight of our company's pipe fittings is heavier than that on the market, (Ensure the back arc thickness) to avoid the parts of the same wall thickness that cannot be seen by the naked eye after the processing The pressure is guaranteed, because many suppliers choose the material to the maximum limit in order to minimize the cost.
