UNS S31254/1.4547 Stainless Steel Pipe Fittings 254SMO/ F44/X1CrNiMoCuN20-18-7

"zheheng steel" produces and supply Wrought Steel Butt-Welding UNS S31254/1.4547 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.

Production Range:

254SMO / F44 / UNS S31254 / 1.4547 / X1CrNiMoCuN20-18-7
Main components: 254SMo contains carbon (C) ≤0.02, manganese (Mn) ≤1.00, nickel (Ni) 17.5 ～ 18.5, silicon (Si) ≤0.8 phosphorus (P) ≤0.03, sulfur (S) ≤0.01, chromium (Cr ) 19.5 ～ 20.5, copper (Cu) 0.5 ～ 1.0, molybdenum (Mo) 6.0 ～ 6.5

National standards: UNS S31254, DIN / EN 1.4547, ASTM A280, ASME SA-280

Supporting welding materials: ERNiCrMo-3 welding wire, ENiCrMo-3 welding rod

Application areas:

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.

what is UNS S31254 ?

UNS S31254 is a stainless steel alloy material with corrosion resistance. The high molybdenum content and high chromium and nitrogen content make it have excellent resistance to pitting corrosion and crevice corrosion. The addition of copper improves the corrosion resistance in certain acids. In addition, due to its high nickel content and high chromium and molybdenum content, UNSS31254 has good resistance to stress corrosion cracking.
