Hastelloy C-276-ANPING JOINWE WIRE MESH CO., LTD

PRODUCTION DESCRIPTION

HASTELLOY C276 is a Nickel-chromium-molybdenum wrought alloy that is considered the most versatile corrosion resistant alloy available. This alloy is resistant to the formation of grain boundary precipitates in the weld heat-affected zone, thus making it suitable for most chemical process applications in an as welded condition.

HASTELLOY C276

Hastelloy C-276 alloy is a nickel-molybdenum-chromium-iron-tungsten series nickel-based alloy. It is one of the most corrosion-resistant modern metal materials. Mainly resistant to wet chlorine, various oxidizing chlorides, chloride salt solutions, sulfuric acid and oxidizing salts, and has good corrosion resistance in low and medium temperature hydrochloric acid. Therefore, in the past thirty years, it has been widely used in harsh corrosive environments, such as chemical industry, petrochemical industry, flue gas desulfurization, pulp and paper making, environmental protection and other industrial fields. The various corrosion data of Hastelloy C-276 alloy are typical, but they cannot be used as specifications, especially in unknown environments, and materials must be selected after testing. There is not enough Cr in Hastelloy C-276 alloy to resist corrosion in strong oxidizing environments, such as hot concentrated nitric acid. The production of this alloy is mainly for chemical process environments, especially in the presence of mixed acids, such as the discharge pipe of flue gas desulfurization systems.

Application:

Digesters and bleach plants in the paper industry. Components exposed to sour gas. Equipment for flue-gas desulfurisation plants. Evaporators, heat exchangers, filters and mixers used in sulfuric acid environments. Sulfuric acid reactors. Organic chloride process equipment. Equipment for processes utilizing halide or acid catalysts.

WIRE DIAMETER:

1. High strength, high bearing capacity
2.Corrosion resistance, rust resistance
3. High tensile strength, high elongation.
4. Good softness and flexibility,can be bent to various shapes 5. Electrical conductivity
6.It is convenient to use
7.Various types and specifications.
