0.015～0.050%, surplus is Fe and inevitable impurity；
Preparation method, comprises the following steps:
(1) steel scrap is melted in electric arc furnace smelting, carry out desulfurization, deoxidation；
(2) alloying: be sequentially added into manganese, nickel, aluminum, boron, silicon, copper, tungsten, titanium carry out alloying；
(3) molten steel is poured in refining furnace, add refining agent and carry out refine, the accurate control composition of LF refining process, ladle
Keep clean Argon 3-5 minute, 15-20 minute refining process dwell time of VD；
(4) casting, continuous casting billet carries out slow cooling, makes the gas in slab sufficiently be spread discharge, at utmost reduces
Slab gas content；
(5) casting after-baking, hardening heat 800-850 DEG C, temperature retention time 30 minutes, shrend；Temperature is 550-600
DEG C, temperature retention time 90 minutes, cool down the most in atmosphere；
(6) two-stage control is used to roll, stage start rolling temperature >=1050 DEG C, two-stage start rolling temperature >=880 DEG C, eventually
Roll temperature 750～800 DEG C roll rear air cooling；
