低碳钢和低合金钢中厚板的性能取决于钢板的组织状态和结构,不同厚度的钢板和不同的热轧工艺可以得到不同的组织状态,一般随着钢板厚度的增加,其强度和韧性有下降的趋势。为了确定σ_s≥36kgf/mm~2级高
The performance of mild steel and low alloy steel plate depend on the state and structure of the steel plate, different thickness of the plate and different hot-rolled process can get different state of the organization, generally with the increase of the thickness of the plate, its strength and toughness There is a downward trend. In order to determine σ_s ≥ 36kgf / mm ~ 2 level high
