Abstract
The invention discloses high-strength die steel. The high-strength die steel comprises, by weight, 0.15-0.18 percent of C, 0.7-0.9 percent of Mn, 0.3-0.6 percent of Si, 0.03-0.05 percent of S, 0.5-0.8 percent of V, 0.8-1.5 percent of W, 0.2-0.5 percent of Nb, and the balance Fe and impurities which cannot be removed. The high-strength die steel has the advantages of being high in precision, performance and efficiency, a manufactured tool has the long service life, the processing process is simple, the performance cost ratio of the high-strength die steel is high, and the high-strength die steel is suitable for large-area application and popularization in the field of industrial manufacturing.
Description
Technical field
The present invention relates to a kind of steel alloy, especially a kind of high-strength die steel.
Background technology
Development along with mould industry, the extensive application of high quality, high-performance, high-level efficiency mould, the intensity of mould and life-span cause common people's concern gradually, in traditional moulds steel, have a large amount of eutectic carbidess, easily produce netted or banded segregation, the large reason of martensite fragility makes its poor toughness simultaneously, fatigue resistance is low, thereby have a strong impact on the obdurability of mould, in military service, easily produce tipping and Brittle Failure (accounting for more than 45%), totally unfavorable to the working life of mould.Therefore, need a kind of new material to solve the problems referred to above.
Summary of the invention
The invention provides a kind of high-strength die steel.
The present invention is directed to the technical scheme that above-mentioned technological deficiency proposes is:
A kind of high-strength die steel, add each element according to weight percent meter, its composition is: C:0.15%-0.18%, Mn:0.7%-0.9%, Si:0.3%-0.6%, S:0.03%-0.05%, V:0.5%-0.8%, W:0.8%-1.5%, Nb:0.2%-0.5%, all the other are Fe and not removable impurity.
Described addition element according to weight percent is: C:0.10%-0.15%, Mn:0.75%-0.95%, Si:0.35%-0.5%, S:0.025%-0.04%, V:0.6%-0.9%, W:1.0%-1.5%, Nb:0.18%-0.55%, all the other are Fe and not removable impurity.
Described addition element according to weight percent is: C:0.12%-0.20%, and Mn:0.8%-1.0%, Si:0.25%-0.7%, S:0.02%-0.04%, V:0.7%-0.9%, W:1.2%-1.8%, Nb:0.25%-0.65%, all the other are Fe and not removable impurity.
The invention has the beneficial effects as follows: precision is high, performance is high, efficiency is high, intensity is high, and the cutter of made has the longer life-span, and work program is simple, and its cost performance is high, the spread that is applicable to industry manufacture field is used.
