Abstract
The invention discloses a hot-work die steel. The hot-work die steel comprises the following components in parts by weight: at most 3 parts of carbon, 0.5-0.8 part of manganese, at most 2 parts of niobium, 40-50 parts of iron, 10-12 parts of aluminum, 0.12-0.35 part of silver, at most 2 parts of copper, at most 0.5 part of phosphorus and 0.01-0.05 part of gold. According to the invention, silver, aluminum and copper are added to enhance heat resistance of the die steel, other composites are added to effectively improve stability and toughness of the die steel, so as to largely prolong service life of the die steel to satisfy demands of the automobile industry.
Description
Technical field
The present invention relates to a kind of die steel, particularly relate to a kind of hot-work die steel.
Background technology
Along with the development of automobile industry and relevant industries, more and more higher to the processing request of spare and accessory parts, a lot of spare and accessory parts have adopted to be produced without the mold cut.Hot-work die subjects very large pressure and impact loading at work, and frequency of impact is very high, die cavity contacts with hot metal, also to stand heating and cooling repeatedly, under sometimes cold and sometimes hot state, the working-surface of mould is easily made to produce heat fatigue cracking, when red-hot metal is forced distortion in addition, with mold cavity surface friction, mould very easily weares and teares and hardness reduces.The demand in market can not be met.
Therefore, for solving the problem, spy provides a kind of new technical scheme.
Summary of the invention
The invention provides a kind of hot-work die steel.
The technical solution used in the present invention is:
A kind of hot-work die steel, comprises the component of following weight part:
The carbon of 3 parts at the most;
The manganese of 0.5-0.8 part;
The niobium of 2 parts at the most;
The iron of 40-50 part;
The aluminium of 10-12 part;
The silver of 0.12-0.35 part;
The copper of 2 parts at the most;
The phosphorus of 0.5 part at the most;
The gold of 0.01-0.05 part.
Further, the calcium of 0.25-0.35 weight part is also comprised.
Further, the tungsten of 0.1-0.5 weight part is also comprised.
The invention has the beneficial effects as follows: with the addition of silver, aluminium and copper, can strengthen the thermotolerance of die steel, the interpolation of other composition effectively can improve stability and the toughness of die steel, substantially prolongs the work-ing life of die steel, meets the demand of automobile industry.
