High-temperature-resistant enameling low-carbon hot-rolled high-strength enameling steel with yield strength of 360 MPa and production method thereof

The invention provides high-temperature-resistant enameling low-carbon hot-rolled high-strength enameling steel with the yield strength of 360 MPa and a production method of the enameling steel. The enameling steel comprises 0.050%-0.100% of C, 0.010%-0.030% of Si, 0.350%-0.550% of Mn, smaller than or equal to 0.015% of P, smaller than or equal to 0.010% of S, 0.025%-0.070% of Al, smaller than or equal to 0.010% of N, 0.020%-0.070% of Ti, 0.010%-0.050% of Nb, 0.050%-0.190% of Mo, 2Ti + Nb = Mo and the balance Fe and inevitable impurities. Compared with the prior art, according to the designed components and the matched production method, the yield strength of the product is 400-440 Mpa, the tensile strength can reach 500 Mpa, the percentage elongation after fracture is larger than 20%, and the yield strength after enameling can be kept to be 85% or above of the yield strength before enameling. 本发明提供了一种耐高温搪烧的屈服强度360MPa级低碳热轧高强搪瓷钢及其生产方法，C：0.050％～0.100％、Si0.010％～0.030％、Mn：0.350～0.550％、P≤0.015％、S≤0.010％、Al：0.025～0
