P≤0.020%, the impurity in steel is more few better.
S≤0.020%, the impurity element in steel is more few better.
Al 0.02%~1.00%, the influence to Austenite Morphology is similar to Si, is also as non- Carbide former, promotes C to be enriched with to austenite and suppress the precipitation of cementite.Al is also AlN precipitations can be formed, certain Grain refinement is played.
Cr0.5-1.5% can effectively improve the quenching degree of steel and prevent high temperature surface oxidation.
Mo0.15-1.50%Mo effectively improves the quenching degree of steel, additionally it is possible to strengthen crystal boundary.Contain Amount is difficult to function as described above less than 0.15%, but too high levels then above-mentioned action effect saturation, And it is relatively costly.
Ni0.5-2.0%Ni is austenitizing stable element, can effectively reduce Ms points, together When can improve material plasticity and low-temperature flexibility, but Ni prices are high.
Cu0.20-0.80% realizes precipitation strength by separating out ε-Cu, improves the intensity of steel.
B0.001-0.005 can significantly improve the quenching degree and purification crystal boundary of steel.Content is less than Act on substantially, during higher than 0.0050% not acting on more than when 0.001% and increase unobvious.Therefore, As added, B content should be controlled in 0.001-0.0050wt% scopes
V0.10-0.50%, Ti0.02-0.20%, Nb0.02-0.20%, to crystal grain refinement, phase transformation C enrichments play remarkable effect in behavior, austenite.The Nb of solid solution condition postpones thermal deformation Static and dynamic recrystallization and austenite are to ferritic phase transformation in journey, so as to expand dynamic tie again Temperature range between brilliant final temperature and Ac3, to be provided just in Unhydrated cement rolling Profit.Nb and C and N combines to form tiny carbonitride can also postpone recrystallization, prevent iron Ferritic crystal grain is grown up, so that with strong refined crystalline strengthening effect and stronger precipitating reinforcing effect. Ti, V have the effect of precipitation strength.
