Title:
HIGH-STRENGTH HIGH-ELONGATION TINNED PRIMARY PLATE AND DOUBLE COLD REDUCTION METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2017/219828
Kind Code:
A1
Abstract:
A high-strength high-elongation tinned primary plate and a double cold reduction method therefor. The tinned primary plate comprises the following components in mass percentage: C: 0.065% to 0.12%, Mn:0.2% to 0.8%, Al:0.01% to 0.08％, N:0.003% to 0.015%, and the balance Fe and inevitable purities. The tinned primary plate needs to processed by using double cold reduction, the ratio of the double cold reduction is controlled to range from 5% to 13%, and the rolling tension ranges from 50 MPa to 100 MPa. The yield strength of the tinned primary plate after being roasted and hardened satisfies RP0.2 ≥ 520 MPa, the rolling direction RD is 45°, the elongations A in the perpendicular direction TD are all greater than or equal to 10%.
