Chemical composition

Physical properties:

minimum mechanical properties in the room temperature

Characteristic

1.Excellent corrosion resistance to most of corrosion media in oxidation and reduction environments.

2.Excellent resist pitting, crevice corrosion and stress corrosion cracking performance.

Metallurgical structure It is face-centered cubic lattice structure.

Corrosion resistance It suit for many kinds of chemical process industry which contain the oxidizing medium and reductant. High molybdenum and chromium content make it can resist the chloride corrosion, and tungsten make it corrosion resistance better.C276 is one of a few material that can resist the corrosion of most chlorine, hypochlorite and chlorine dioxide, this alloy have prominent corrosion resistance to high concentration chlorate( iron chloride and copper chloride).

Application field: It is widely used in the chemical field and petrifaction field, such as the element of chloride organic and catalyze system.This material especially suit for high temperature environment, impure inorganic acid and organic acid (such as formic acid and acetic acid), sea-water corrosion environment.

The digester and bleacher in the use of paper pulp and paper making industry.

Absorption tower, re-heater and fan in the FGD system.

The equipment and parts in the use of acidic gas environments.
