Abstract
The invention provides high-strength alloy steel, relating to the technical field of steel. The high-strength alloy steel is characterized by comprising 0.43-0.48% of C, 0.185% of Si, 0.50-0.80% of Mn, not more than 0.25% of Cr, not more than 0.30% of Ni, not more than 0.25% of Cu and the balance of Fe. The high-strength alloy steel has good high temperature resistance effects, is low in production cost, is reasonable in components and has obvious comprehensive property effects. A production process of the high-strength alloy steel is simple and is convenient to control.
Description
Technical field:
The present invention relates to steel technical field, specifically a kind of high-strength alloy steel.
Background technology:
Outside deironing in steel alloy alloy steel steel, carbon, add other alloying element, be just steel alloy.General carbon steel basis is added one or more appropriate alloying elements and the iron-carbon formed.According to the difference of Addition ofelements, and take suitable complete processing, high strength, high tenacity, the property such as wear-resisting, corrosion-resistant, low temperature resistant, high temperature resistant, nonmagnetic can be obtained.The existing rare metal added when the steel alloy produced is comparatively simple, generally is single rare metal, only has comparatively single effect, and existing not obvious.
Summary of the invention:
It is reasonable that technical problem to be solved by this invention is to provide a kind of component, the resistance to high-strength alloy steel of the successful of over-all properties.
Solve technical problem adopt following technical scheme:
A kind of high-strength alloy steel, is characterized in that: in its Raw, carbon content is 0.43-0.48%, Si content is 0.185%, Mn content 0.50-0.80%, Cr content≤0.25%, and Ni content≤0.30%, Cu content≤0.25%, all the other are iron.
In its Raw of preferred technical scheme, carbon content is 0.45%, Si content is 0.185%, Mn content 0.6.5%, and Cr content is 0.17%, Ni content be 0.18%, Cu content is 0.20%, and all the other are iron.
Containing the titanium of 0.6% in described raw material.
C: ensure the carbon of formation required for carbide and ensure the hardness that quenched martensite can obtain,
Si: silicon can stop carbide forming core to be grown up, makes " C " curve move to right, and improves the hardening capacity of steel, can also improve the temper resistance of steel, improve the comprehensive mechanical performance to steel.
Mn: Main Function is the hardening capacity improving steel, increases intensity and the hardness of steel, has effect of deoxidation and desulfurization (forming MnS), prevents hot-short.Can also improve cementation zone, be conducive to cementation zone and thicken, increase condensate depression during austenite cooling, refine pearlite tissue is to improve mechanical property.
Cr: can improve the hardening capacity of steel and have secondary hardening effect, or carbide forming element, improve temper resistance, increases the wear resistance of steel.
Cu: copper is more stable, not easily oxidized, so the copper contained can play corrosion-resistant effect.
Nickel and titanium: the high thermal resistance that can improve steel alloy.
The invention has the beneficial effects as follows: instant component is reasonable, the successful of over-all properties.
