Abstract

The invention discloses a nickel-chromium alloy, which is composed of the following substances by weight percentage: nickel 25-30%, chromium 56-60%, magnesium 2-4%, carbon 0.5-0.8%, manganese 0.2-0.4%, Molybdenum 0.05-0.1%, aluminum 0.6-0.7%, titanium 0.03-0.05%, boron 0.01-0.03%, zinc 0.01-0.04%, and the rest is iron. The beneficial effects of the present invention are as follows: the nickel-chromium alloy provided by the present invention has stronger toughness than before, especially in low temperature environment, compared with the previous nickel-chromium alloy, the toughness is enhanced by 20%-50%, which is an The application of nickel-chromium alloys in the field provides new ideas.

Description

technical field [0001] The invention relates to the field of alloys, in particular to a nickel-chromium alloy. Background technique [0002] Nickel-chromium alloy has high strength and corrosion resistance, and its alloy with iron and nickel is commonly known as stainless steel. It is often used in cutting tools; forms a corrosion-resistant alloy layer on the surface of steel or iron by spraying, deposition and high-temperature diffusion; potassium dichromate and sodium dichromate are strong oxidants in organic synthesis and petroleum industry; chrome yellow , chrome orange, chrome green, etc. can be used as inorganic pigments. However, conventional nickel-chromium alloys have low toughness and are prone to fracture. Contents of the invention [0003] The object of the present invention is to provide a nickel-chromium alloy with high toughness and long service life aiming at the defects in the above-mentioned prior art. [0004] In order to achieve the above object, the...
