Abstract

The invention relates to high-strength memory die steel which is prepared from the following components in percentage by weight: 0.15-0.18% of C, 0.7-0.9% of Mn, 0.3-0.6% of Si, 0.03-0.05% of S, 0.5-0.8% of rare earth, 0.8-1.5% of W, 0.2-0.5% of Ni and the balance of Fe and inevitable impurities. The high-strength memory die steel provided by the invention has the beneficial effects that the steel is high in precision, performance and efficiency, and a prepared cutter is relatively long in service life and simple in workpiece program, and moreover, the steel is high in cost performance, so that the steel is suitable for large-area popularization and use in the field of commercial manufacture.

Description

A kind of high strength memory die steel
Technical field
The present invention relates to a kind of steel alloy, especially a kind of high strength memory 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%) 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 memory die steel.
The present invention is directed to the technical scheme that above-mentioned technological deficiency proposes is:
A kind of high strength memory 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%, rare earth: 0.5%-0.8%, W:0.8%-1.5%, Ni: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%, rare earth: 0.6%-0.9%, W:1.0%-1.5%, Ni: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%, Mn:0.8%-1.0%, Si:0.25%-0.7%, S:0.02%-0.04%, rare earth: 0.7%-0.9%, W:1.2%-1.8%, Ni: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 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.
