1. Introduction
• The various corrosion data of the harness-c-276 alloy are typical, but cannot be used as a specification, especially in unknown environments, materials must be tested before they can be selected.There is not enough Cr in the harrington c-276 alloy to resist corrosion in strongly oxidized environments, such as hot concentrated nitric acid.This kind of alloy is mainly produced in the chemical process environment, especially in the case of mixed acid, such as the flue gas desulfurization system discharge pipe.
• Hartz alloy mechanical properties is very outstanding, it has the characteristics of high strength, high toughness, so has certain difficulty in machining, and the strain hardening tendency is extremely strong, when the deformation rate of 15%, about twice the 18 8 stainless steel.There is also a moderate temperature sensitive zone in haversian alloy, and its susceptibility tends to increase with the increase of the deformation rate.When the temperature is high, the mechanical properties and corrosion resistance of the alloy are decreased because of the easy absorption of harmful elements.

4. Character
The key factors influencing corrosion resistance of this material are the control of impurity S,P, gas content O,N and key elements C,Si, etc.It depends on the control of production process, such as the choice of heating temperature and heat preservation time of forging, such as the guarantee of forging ratio, such as the guarantee of solid solution treatment, etc.
The c-276 hardener alloy belongs to the nickel-molybdenum-chrome-ferro-tungsten nickel-base alloy, which is the most corrosion resistant of modern metal materials.It is mainly resistant to wet chlorine, various oxidizing chlorides, chloride solution, sulfuric acid and oxidizing salt.Therefore, in the last 30 years, in the harsh environment of corrosion, such as chemical, petrochemical, flue gas desulfurization,pulp and paper, environmental protection and other industrial fields have been widely used.
