Abstract

The invention relates to a high temperature resistant die steel. The die steel comprises, by weight, 1-3.5 parts of C, 0.05-0.08 parts of Zn, 0.013-0.025 parts of Mg, 0.057-0.086 parts of Al, 0.036-0.05 parts of grape stalk, 0.03-0.065 parts of Sb, 0.15-0.25 parts of Pb, 0.05-0.063 parts of Y and 80-95 parts of Fe. The die steel has the advantages of scientific and reasonable component proportions, strong high temperature resistance, stable performances, great prolongation of the service life, and realization of unlikely deformation, high tensile strength and high molding precision in use.

Description

A kind of high temperature resistance die steel

Technical field

The present invention relates to a kind of high temperature resistance die steel.

Background technology

Along with scientific and technical development, the scope of mould application is more and more extensive, for the product mold of manufacturing many kinds, short run or frequent updating remodeling as for the moulds such as injection mould, blow die, compression mould, requirement has the advantages that the manufacturing cycle is short, manufacture difficulty is little and cost is low, and the die manufacturing cost conventionally adopting in prior art is high, the cycle is long.Simple metallic iron can not meet as the requirement of the aspects such as plasticity, hardness, intensity, therefore conventionally adds alloying element to improve its physical and mechanical properties.

Therefore,, for addressing the above problem, spy provides a kind of new technical scheme.

Summary of the invention

The invention provides a kind of high temperature resistance die steel.

The technical solution used in the present invention is:

A kind of high temperature resistance die steel, comprises the composition of following weight part:

Carbon 1-3.5 part;

Zinc 0.05-0.08 part;

Magnesium 0.013-0.025 part;

Aluminium 0.057-0.086 part;

Grape stalk 0.036-0.05 part;

Antimony 0.03-0.065 part;

Plumbous 0.15-0.25 part;

Yttrium 0.05-0.063 part;

Iron 80-95 part.

Preferably, can also add the gold of 0.05-0.06 weight part.

Preferably, can also add the caesium of 0.01-0.015 weight part.

Advantage of the present invention is: the composition proportion of this kind of die steel is scientific and reasonable, and high-temperature resistance is strong, and stable performance has extended work-ing life greatly, in use, is not easy distortion, and tensile strength is high, and molding precision is high.
