Description

A kind of high-strength die steel
Technical field
The present invention relates to a kind of steel alloy, especially a kind of high-strength die steel.
Background technology
Along with the development of mould industry, the extensive application of high quality, high-performance, High-efficiency mold, the intensity of mould and life-span cause the concern of common people gradually, there is a large amount of eutectic carbidess in traditional moulds steel, easily produce netted or banded segregation, the reason that martensite fragility is large simultaneously makes its poor toughness, fatigue resistance is low, thus have a strong impact on the obdurability of mould, and easily produce tipping and Brittle Failure (accounting for more than 45 parts) in military service, totally unfavorable to the working life of mould.Therefore, a kind of new material is needed 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 parts by weight, its composition is: C:0.18 part-0.22 part, Mn:0.6 part-0.9 part, Cr:0.3 part-0.7 part, P:0.03 part-0.08 part, Nb:0.4 part-0.9 part, W:0.8 part-1.5 parts, Ti:0.2 part-0.5 part, Ni:0.5-0.8 part, all the other are Fe and not removable impurity.
Co:0.3-0.6 part can also be added.
Al:0.5-0.8 part can also be added.
The invention has the beneficial effects as follows: precision is high, performance is high, efficiency is high, intensity is high, and made cutter has the longer life-span, work program is simple, and its cost performance is high, and the spread being applicable to industry manufacture field uses.
