Abstract

The invention discloses a nickel-silicon-ferro alloy which is characterized by comprising the following components in percentage by weight: 50% to 75% of silicon, 20% to 40% of iron, 10% to 15% of nickel and smaller than or equal to 5% of inevitable impurities of calcium, sulfur, aluminum, manganese, carbon and phosphorus. By adopting the manner, the nickel-silicon-iron alloy provided by the invention can overcome the defects in the prior art and has the advantages of high rigidity, high corrosion resistance, good wear resisting property and the like.

Description

A kind of NiSiFe alloy

Technical field

The present invention relates to metal material field, particularly relate to a kind of NiSiFe alloy.

Background technology

Along with social development, all trades and professions increase day by day for the demand of the various materials such as high temperature steel, weathering steel and steel alloy.Nisiloy iron is multiplex reductor and the alloying constituent done in the steel-making industry, adds the silicon of some amount in steel, can improve significantly the intensity of steel.Consistency and elasticity, improve inclusion simultaneously and reduce elemental gas content in molten steel, is the effective new technology that improves steel quality, reduces costs, economizes on iron.But the nisiloy iron hardness now in technology is not high, corrosion resistance nature is not strong.

Summary of the invention

Main purpose of the present invention is to provide a kind of NiSiFe alloy, can overcome the deficiency in technology now, has the advantages such as hardness is high, erosion resistance is strong, wear resisting property is good.

For solving the problems of the technologies described above, the technical scheme that the present invention adopts is: a kind of NiSiFe alloy is provided, and described NiSiFe alloy contains silicon, iron and calcium, sulphur, aluminium, manganese, carbon, the inevitable impurity of phosphorus, and their weight percentage is:

Silicon 50-75%;

Iron 20-40%;

Nickel 10-15%;

Calcium, sulphur, aluminium, manganese, carbon, the inevitable impurity summation of phosphorus≤5%.

In more excellent example of the present invention, in described NiSiFe alloy, the weight percentage of each composition is:

Silicon 60-75%;

Iron 20-30%;

Nickel 10-15%;

Calcium≤1.5%;

Sulphur≤0.5%;

Aluminium≤2.5%;

Manganese≤0.5%;

Carbon≤0.5%;

Phosphorus≤0.1%.

Silicon 50-60%;

Iron 30-40%;

Nickel 10-15%;

Calcium≤1.5%;

Sulphur≤0.5%;

Aluminium≤2.5%;
