Abstract
The invention discloses high-toughness spring steel which comprises, by weight, 0.19-0.22 percent of C, 0.6-0.75 percent of Mn, 1.0-1.2 percent of Si, 0.08-0.12 percent of Cr, 0.3-0.5 percent of Cu, 0.02-0.03 percent of P, 0.5-0.8 percent of V and the balance Fe and impurities which cannot be removed. Heating, forming, waste heat quenching and medium-temperature tempering are conducted on high-performance spring steel plate materials, and finally, final forming of the shape of a product is conducted. The high-toughness spring steel has the advantages of being good in elasticity, suitable for working normally in a loading environment, high in yield strength in manufacturing spring materials and long in service life and cannot be broken in extremely-severe conditions. The performance cost ratio of the high-toughness spring steel is high, and the high-toughness spring 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-toughness spring steel.
Background technology
Spring steel should have good over-all properties, as mechanical property (particularly elastic limit, breakdown point, yield tensile ratio), elasticity attenuation resistance can (be the elastoresistance performance that goes down, claim again relaxation resistance), fatigue property, hardening capacity, physical and chemical performance (heat-resisting, low temperature resistant, anti-oxidant, corrosion-resistant etc.).In order to meet above-mentioned performance requriements, spring steel has good metallurgical quality (high clarity and homogeneity), good surface quality (strict control surface defect and decarburization), accurate profile and size.Spring steel belongs to steel for mechanical structure; According to quality grade, belong to very special quality steel, need in process of production the steel of special strict control of quality and performance.According to China custom, spring steel belongs to special steel, when making spring steel technical requirements higher, technology really up to the mark directly determines the height of quality.Easily there is brittle failure in current spring steel, also need larger lifting degree to meet modern industry demand under utmost point mal-condition.
Summary of the invention
The invention provides a kind of high-toughness spring steel.
The present invention is directed to the technical scheme that above-mentioned technological deficiency proposes is:
A kind of high-toughness spring steel, add each element according to weight percent meter, its composition is: C:0.19%-0.22%, Mn:0.6%-0.75%, Si:1.0%-1.2%, Cr:0.08%-0.12%, Cu:0.3%-0.5%, P:0.02%-0.03%, V:0.5%-0.8%, all the other are Fe and not removable impurity, described high-performance Steel Spring Plate material through heating, moulding, immediate quenching, average tempering, finally carry out the moulding of product net shape.
Described addition element according to weight percent is: C:0.18%-0.20%, Mn:0.55%-0.75%, Si:1.2%-1.4%, Cr:0.09%-0.15%, Cu:0.4%-0.6%, P:0.015%-0.035%, V:0.55%-0.7%, all the other are Fe and not removable impurity.
Described addition element according to weight percent is: C:0.16%-0.18%, Mn:0.6%-0.7%, Si:1.3%-1.5%, Cr:0.1%-0.13%, Cu:0.35%-0.55%, P:0.018%-0.03%, V:0.45%-0.75%, all the other are Fe and not removable impurity.
The invention has the beneficial effects as follows: good springiness, toughness is high, is adapted at working normally under load environment, has higher yield strength, and has the longer life-span, and can under utmost point mal-condition, not occur the problem of brittle failure to manufacturing spring material.And its cost performance is high, the spread that is applicable to industry manufacture field uses.
