Abstract
The present invention relates to a kind of high nichrome of good toughness resistance, it is made up of the chemical composition of following percentage by weight：Chromium 20 25%, zirconium 0.3 0.5%, bismuth 1 2%, carbon 0.3 0.8%, phosphorus 0.1 0.2%, arsenic 0.5 0.9%, lanthanum 0.4 0.8%, surplus is nickel.Nichrome provided by the invention, due to the addition of metal zirconium and lanthanum material so that this steel alloy has higher fusing point, can be resistant to 1200 DEG C of high temperature above for a long time, and have preferable tensile strength and yield strength and high surfaceloadingrate.Zirconium forms zirconium oxide protective layer with air contact, and the antioxygenic property on its surface is greatly enhanced, and can produce far infrared, and heating is uniform so that for the maximum operation (service) temperature of this steel alloy up to 1400 DEG C, its surface loading can reach 6W/cm2。
Description
Technical field
The present invention relates to alloy field, and in particular to a kind of high nichrome of good toughness resistance.
Background technology
Nichrome has high intensity and corrosion resistance, and the alloy formed with iron and nickel is commonly called as stainless steel.It is usually used in cutting
Instrument is cut, corrosion-resisant alloy layer, potassium bichromate and again are formed on the surface of steel or iron with the methods of spraying plating, deposition and High temperature diffusion
Sodium chromate is that the strong oxidizer in organic synthesis and petroleum industry field, chrome yellow, chrome orange, chrome green etc. can be used as inorganic pigment.But with
Past nichrome toughness is low, is easily broken off.
The content of the invention
The defects of purpose of the present invention is aiming at above-mentioned prior art, there is provided a kind of toughness is high, service life is grown
Nichrome.
To achieve these goals, the technical scheme that the present invention takes is as follows：
A kind of high nichrome of good toughness resistance, is made up of the chemical composition of following percentage by weight：Chromium 20-25%,
Zirconium 0.3-0.5%, bismuth 1-2%, carbon 0.3-0.8%, phosphorus 0.1-0.2%, arsenic 0.5-0.9%, lanthanum:0.4-0.8%, surplus are
Nickel.
Further, it is made up of the chemical composition of following percentage by weight：Chromium 23%, zirconium 0.3-0.4%, bismuth 1.5%, carbon
0.5%th, phosphorus 0.2%, arsenic 0.7%, lanthanum 0.5-0.7%, surplus are nickel.
Further, the percentage by weight of zirconium is 0.3%.
Further, the percentage by weight of zirconium is 0.4%.
Further, the percentage by weight of lanthanum is 0.5%.
Further, the percentage by weight of lanthanum is 0.6%.
Further, the percentage by weight of lanthanum is 0.7%.
Beneficial effects of the present invention are：Nichrome provided by the invention, due to the addition of metal zirconium and lanthanum material so that
This steel alloy has higher fusing point, can be resistant to 1200 DEG C of high temperature above for a long time, and have preferable tensile strength and surrender
Intensity and high surfaceloadingrate.Zirconium forms zirconium oxide protective layer with air contact, and the antioxygenic property on its surface obtains significantly
Improve, and far infrared can be produced, heating is uniform so that the maximum operation (service) temperature of this steel alloy is up to 1400 DEG C, its surface loading
It can reach 6W/cm2。
