note：Tempering sensitivity modulus should meet the following embrittlement requirements：
J=(Si_Mn)(P+Sn)×104≤100（％）
（P＋Sn）≤0.014
Element in the formula should replaced by percentage content。
4. Delivery status: the steel plate to normalizing + tempering state delivery.
5. Mechanical properties
The mechanical properties of the steel plate should be in accordance with table 2 and the provisions of the table 3 (sample for simulation of heat treatment after state)
