Product Description

Product Description

Hastelloy is a nickel-based corrosion-resistant alloy, mainly divided into two categories: nickel-chromium alloys and nickel-chromium-molybdenum alloys. Hastelloy has good corrosion resistance and thermal stability, and is mostly used in the aviation business, chemical field, etc.

Classification

Hastelloy plates are suitable for use in a variety of chemical industries that contain oxidizing and reducing media. The higher molybdenum and chromium content enables the alloy to resist chloride ion corrosion, and the tungsten element further improves corrosion resistance. Meanwhile C-276 Hastelloy tube is one of only a few materials resistant to corrosion by moist chlorine, hypochlorite and chlorine dioxide solutions, and has significant corrosion resistance to highly concentrated chloride salt solutions such as ferric chloride and copper chloride.Application areas: heat exchangers, bellows compensators, chemical equipment, flue gas desulfurization and denitrification, paper industry, aerospace applications, acidic environments .

Hastelloy grades

Hastelloy (Hastelloyalloy) is mainly divided into B, C, G three series, it is mainly used for iron-based Cr-Ni or Cr-Ni-Mo stainless steel, non-metallic materials and other strong corrosive media occasions can not be used.In order to improve the corrosion resistance and cold and hot processing performance of Hastelloy, Hastelloy has made three major improvements, and its development process is as follows.B series: B → B-2 (00Ni70Mo28) → B-3C series: C → C-276 (00Cr16Mo16W4) → C-4 (00Cr16Mo16) → C-22 (00Cr22Mo13W3) → C-2000 (00Cr20Mo16)G series: G → G-3 (00Cr22Ni48Mo7Cu) → G-30 (00Cr30Ni48Mo7Cu)The most widely used are the second generation materials N10665 (B-2), N10276 (C-276), N06022 (C-22), N06455 (C-4) and N06985 (G-3).



Hastelloy alloy is a generic name for the commercial grades of nickel-based corrosion-resistant alloys produced by Hastelloy International, Inc. These include nickel-molybdenum Hastelloy B-2, nickel-chromium-molybdenum Hastelloy C-4, etc.
Hastelloy grades include the following grades.
HASTELLOY B-2 Nickel-molybdenum alloy with excellent corrosion resistance in reducing environments HASTELLOY B-3 An upgraded version of B-2 with excellent corrosion resistance to hydrochloric acid at any temperature and concentration.
HASTELLOY C-4 Better thermal stability, good toughness and corrosion resistance at 650-1040 degrees C
HASTELLOY C-22 Better resistance to uniform corrosion in oxidizing media than C-4 and C-276, excellent resistance to localized corrosion HASTELLOY C-276 Better resistance to oxidizing and moderate reducing corrosion, excellent resistance to stress corrosion HASTELLOY C-2000 The most versatile corrosion resistant alloy, in both oxidizing and reducing environments Excellent resistance to uniform corrosion.
HASTELLOY G-35 An upgrade of G-30 with better corrosion resistance and thermal stability HASTELLOY G-30 A nickel-based alloy with high chromium content that performs well in phosphoric acid and other strong oxidizing acid mixtures
HASTELLOY X combines high strength, oxidation resistance and easy processing characteristics of each grade above have specific chemical composition, mechanical properties, each has its own strengths, can not be generalized to say what characteristics of Hastelloy.
