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 the development of science and technology, the increasing extent of mould application is extensive, for manufacturing the product mold of multi items, short run or frequent updating remodeling as the moulds such as injection mould, blow die, compression mould, require to have that the manufacturing cycle is short, manufacture difficulty is little and the feature that cost is low, and the die manufacturing cost usually adopted in prior art is high, the cycle is long.Simple metallic iron can not meet the requirement as aspects such as plasticity, hardness, intensity, therefore usually adds alloying element to improve its physical and mechanical properties.

Therefore, for solving the 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;

Tin 0.036-0.05 part;

Fluorite 0.03-0.065 part;

Plumbous 0.15-0.25 part;

Yttrium 0.05-0.063 part;

Iron 80-95 part.

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

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

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, substantially prolongs work-ing life, and in use, be not easy distortion, tensile strength is high, and molding precision is high.
