Abstract

The invention discloses high temperature heat-resisting die steel which comprises the following ingredients, by weight, 0.3-0.35% of carbon, 0.02-0.2% of silicon, 0.25-0.3% of aluminium, 0.09-0.12% of potassium, 0.5-1.2% of bamboo charcoal, 0.3-0.5% of manganese, 0.01-0.03% of platinum and the balance iron. The high temperature heat-resisting die steel has beneficial effects of scientific and reasonable ingredients, stable performance, long service life, good toughness, high strength and strong high temperature resistance.

Description

A kind of high-temperature heat-resistance die steel

Technical field

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

Background technology

At present, die steel material realizes one of the modern basis of production and core technology, and its developmental level is the leading indicator of the national production level height of measurement one.Hot-work die steel generally operates under suitable complex work condition, and the performance requriements for die steel material is also quite strict.And the hot-work die steel of domestic production, the tropism such as grade of steel is lower, and homogeneity of structure is poor, and the mould synthetic performance examination produced is lower, seriously limits work-ing life.

Therefore, for solving the problem, spy provides a kind of new technical scheme to satisfy the demands.

Summary of the invention

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

The technical solution used in the present invention is:

A kind of high-temperature heat-resistance die steel, comprises the component composition of following weight percent:

Carbon 0.3-0.35%;

Silicon 0.02-0.2%;

Aluminium 0.25-0.3%;

Potassium 0.09-0.12%;

Bamboo charcoal 0.5-1.2%;

Manganese 0.3-0.5%;

Platinum 0.01-0.03%;

Surplus is iron.

The glass fibre that weight percent is 0.6-1.8% can also be added.

The invention has the beneficial effects as follows: this kind of high-temperature heat-resistance die steel component is scientific and reasonable, stable performance, long service life, and good toughness, intensity is high, and high-temperature resistant result is strong.
