主要用于制造桥梁、船舶、车辆、锅炉、高压容器、输油输气管道、大型钢结构等。

Mainly used in the manufacture of bridges, ships, vehicles, boilers, high pressure vessels, oil and gas pipelines, large steel structures, etc..

16Mn 是我国低合金高强钢中用量最多、产量最大的钢种。使用状态的组织为细晶粒的铁素体—珠光体，强度比普通碳素结构钢Q235高约20%～30%，耐大气腐蚀性能高20%～38%。

16Mn is China's low alloy high strength steel up to yield the maximum amount of steel. Using the state of the organization for the fine grain ferrite pearlite, strength than ordinary carbon structural steel Q235 about 20% ~ 30%, high atmospheric corrosion resistance of 20% ~ 38%.

15MnVN   中等级别强度钢中使用最多的钢种。强度较高，且韧性、焊接性及低温韧性也较好，被广泛用于制造桥梁、锅炉、船舶等大型结构。

15MnVN     the largest steel use medium strength steel in. High strength, toughness, weldability and low temperature toughness is also widely used in the manufacture of bridges, boilers, ships and other large structures.

强度级别超过500MPa后，铁素体和珠光体组织难以满足要求，于是发展了低碳贝氏体钢。加入Cr、Mo、Mn、B等元素，有利于空冷条件下得到贝氏体组织，使强度更高，塑性、焊接性能也较好，多用于高压锅

The intensity level of more than 500MPa, ferrite and pearlite can not meet the requirements, so the development of low carbon bainitic steel. By adding Cr, Mo, Mn, B and other elements, it can be used to obtain bainite structure under the condition of air cooling, so that the strength is higher, the plasticity and the welding performance are better, and the utility model is used for the pressure cooker
