Abstract

The invention discloses a hot-working die alloy. The hot-working die alloy comprises following ingredients, by weight, 0.3 to 0.35% of carbon, 0.02 to 0.2% of silicon, 0.3 to 0.36% of silver, 0.09 to 0.12% of potassium, 0.05 to 0.09% of yttrium, 0.3 to 0.5% of vanadium, 0.01 to 0.03% of platinum, and the balance iron. Beneficial effects are that: composition of the hot-working die alloy is scientific and reasonable; performance is stable; and service life is long.

Description

A kind of hot-work die alloy

Technical field

The present invention relates to a kind of hot-work die alloy.

Background technology

At present, hot-work die alloy 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 alloy generally operates under suitable complex work condition, and the performance requriements for die steel material is also quite strict.And the hot-work die alloy 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 hot-work die alloy.

The technical solution used in the present invention is:

A kind of hot-work die alloy, comprises the component composition of following weight percent:

Carbon 0.3-0.35%;

Silicon 0.02-0.2%;

Silver 0.3-0.36%;

Potassium 0.09-0.12%;

Yttrium 0.05-0.09%;

Vanadium 0.3-0.5%;

Platinum 0.01-0.03%;

Surplus is iron.

The antimony that weight percent is 0.07-0.1% can also be added.

The tin that weight percent is 0.02-0.06% can also be added.

The invention has the beneficial effects as follows: this kind of hot-work die alloy compositions is scientific and reasonable, stable performance, long service life.
