Sachiya Steel International is a known Manufacture, Stockist and Exporter unit of Alloy Steel F91 Nipple, which are steels by means of having superior machining properties. By means of increasing amounts of corrosion relative to abrasion, the wear resistance of our Alloy Steel F91 Hexagon Reducing Nipple is seen to improve dramatically with respect to mild steel or other grades of proprietary abrasion – resistant materials.

This Alloy Steel F91 Hexagon Nipple is dual stabilized with niobium and titanium to provide good weld ductility and resistance to inter – granular corrosion in the weld heat affected zone, which can be formed using a wide range of roll forming, mild stretch – bending or common drawing operations. Furthermore, our sales personnel are trained extensively to understand the product qualities of our Alloy Steel F91 One End Threaded Nipple and applications associated by means of specialty steels and this knowledge is used to service the requirements of our customers.

This Alloy Steel F91 Both End Threaded Nipple also offers higher creep, stress – to – rupture, and tensile strength at elevated temperatures. In addition to excellent corrosion resistance and strength properties, our Alloy Steel F91 Concentric Swaged Nipple as well provides excellent fabricability and formability which are typical of the austenitic stainless steels. We at Sachiya Steel International support our customers and represent our suppliers with high caliber technical personnel and laboratory facilities for to manufacture this Alloy Steel F91 Eccentric Swaged Nipple.
