F55/S32760 Stainless Steel Pipe Fittings Duplex steel butt welding seamless and welded
"zheheng steel" produces and supply Wrought Steel Butt-Welding F55/S32760 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. The materials used are special steel materials such as F51/S31803/F53/S32750/F55/S32760/F59/S32520/F60/S32205/F904L/N08904
UNS S32760 is a super duplex stainless steel. Contains 0.75% tungsten and copper, 25% chromium (austenitic / ferritic) steel. The supplied PREn (in terms of pitting equivalent) of this alloy is> 40.0, which ensures a high pitting resistance. Zeron 100 has high mechanical strength, good ductility, and corrosion resistance to the marine environment at atmospheric and sub-zero temperatures. Good resistance to abrasion, corrosion and cavitation and can also be used in the working environment of acidic medium. Mainly used in oil and gas and hundred marine applications, usually used in pressure vessels, choke valves, Christmas trees, flanges and piping systems.

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.
