The effect of the above each main component:
Carbon: carbon is one of efficient hardening element ensureing steel acquisition high strength, high rigidity, and it can significantly improve intensity and the hardness of steel, prevents from occurring ferrite in quenching structure.Add-on is too much, and matrix fragility increases, plasticity declines.
Silicon: the activity of carbon in austenite can be increased, in bainite ferrite process of growth, unnecessary carbon can discharged in the contiguous austenite of side, interface, because silicon hinders cementite to separate out, cause the rich carbon of austenite around, make the rich carbon retained austenite stabilization between bainite ferrite slip or in slip, form carbide-free Bainite.When silicone content is lower, because silicon suppresses the effect of Carbide Precipitation more weak, promote that the effect of bainite transformation is not strong yet, in isothermal transformation, first separate out bainite at austenite grain boundary, and the austenite do not changed changes martensite in process of cooling subsequently, its microstructure is made up of bainite ferrite, martensite and a small amount of residual austenite, there is high intensity, hardness, and impelling strength and fracture toughness property lower; When silicone content is higher, occurs in tissue a large amount of not changing austenite structure, cause the hardness of material to decline.
Manganese: mainly in order to improve the hardening capacity of steel, add-on is too much, will the tissue of alligatoring steel, increases hot cracking tendency, considers, controlled be less than 1.00% by its content.
Sulphur the: add≤sulphur of 0.030% in steel, can machinability be improved.
Chromium: can significantly improve intensity, hardness and wear resistance, can also improve oxidation-resistance and the erosion resistance of steel.
Nickel: nickel can improve the intensity of steel, and keep good plasticity and toughness.Nickel has higher corrosion resistance to soda acid, at high temperature has antirust and temperature capacity.
Copper: intensity and toughness can be improved, particularly atomospheric corrosion performance.
After thermal treatment, material hardness of the present invention reaches HRC42-47, and microstructure is equally distributed martensitic aging tissue and strengthening phase, does not find δ-ferrite.
The elastomer material that above embodiment is formed, obtains following experimental data through experiment:
| Embodiment 1 | Embodiment 2 | Embodiment 3 | Embodiment 4 | |
| Breakdown point/kg/mm 2 | 125 | 130 | 135 | 138 |
