Abstract

The invention relates to an alloy formula, in particular to an oxidation-corrosion-resistant nickel-based alloy. The nickel-based alloy is characterized by comprising the following components of, by weight, 34-40% of iron, 1.5-2.5% of manganese, 0.02% of aluminum, 0.02% of titanium and the balance nickel. According to the optimal technical scheme, the nickel-based alloy comprises the following components of, by weight, 36% of iron, 2.0% of manganese, 0.02% of aluminum and 0.02% of titanium and the balance nickel. Thus, the oxidation-corrosion-resistant nickel-based alloy has the advantages ofbeing low in cost, good in oxidation corrosion resistant effect and high in corrosion resistance.

Description

technical field [0001] The invention relates to a formula of an alloy, in particular to a formula of a nickel base alloy with anti-oxidation and corrosion capability. Background technique [0002] The existing anti-oxidation and corrosion tools are generally made of beryllium green manganese, which is relatively high in cost and limited in application; in addition, its corrosion resistance is relatively small, and it is difficult to meet the requirements of some places. Contents of the invention [0003] The object of the present invention is to address the above disadvantages and provide a nickel-based alloy with low cost, good oxidation and corrosion resistance and high hardness. [0004] The technical solution of the present invention is achieved in the following way: a nickel base alloy with anti-oxidation and corrosion capability is characterized in that: it contains 34-40% iron, 1.5-2.5% manganese, 0.02% aluminum and 0.02% titanium by weight , the rest is nickel. ...
