Hastelloy Fasteners can be used in application involving wide range of medium including reducing acids and oxidizing agents. Being the most versatile, alloy c276 fasteners are most commonly used for bolting among all hastelloy grade fasteners. Resitant Metal Alloys Fasteners is a well known manufacturer and supplier of hastelloy c276 fasteners offering bolts, screws, stud bolts, threadd rods, nuts, washers and custom fasteners in hastelloy c276 alloy.
Hastelloy C276 is a nickel-molybdenum-chromium alloy with an addition of tungsten designed to have excellent corrosion resistance in a wide range of severe environments. Also known as Alloy C276 The high nickel and molybdenum contents make this alloy specially resistant to pitting and crevice corrosion in reducing environments while chromium conveys resistance to oxidizing media. The low carbon content minimizes carbide precipitation during welding to maintain corrosion resistance in as-welded structures.
