Presently, our company got a purchase order for Hastelloy C276 flange and Hastelloy B-2 flushing ring used in pressure gauges. Hastelloy alloy is a nickel-based alloys, mainly divided into B,C,G of the three series, which used in those strong corrosive medium where iron Cr-Ni or Cr-Ni-Mo stainless steel, non-metallic materials can not be. It is widely used in petroleum, chemical industry, environmental protection and many other fields abroad.

 Hastelloy C276(NS334), it has excellent corrosion resistance for oxide & chloride solution and wet chloride, hypochlorous acid. It can be used for strong corrosive oxidation - reduction complex media application.
Hastelloy B-2(NS322), it can withstand strong reduction media, improve intergranular corrosion resistance. It can be used in hydrochloric acid and sulfuric acid with middle concentration at high temperature.
