| Hastelloy C-276 Corrosion resistance | |||||
| C276 alloy 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). | |||||
| Hastelloy C-276 Application field: | |||||
| C276 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. | |||||
| Hastelloy C-276 Other application field: | |||||
| 1. The digester and bleacher in the use of paper pulp and paper making industry. | |||||
| 2. Absorption tower, re-heater and fan in the FGD system. | |||||
| 3. The equipment and parts in the use of acidic gas environments. | |||||
