20CrNi3A淬透性良好，能在大的截面范围内获得均匀的强度。经调质或淬火加低温回火后，有良好的综合力学性能。切削加工性良好，冷变形塑性和焊接性中等。有形成白点的敏感性，高温回火时有回火脆性倾向。20CrNi3A用作高负荷条件下工作的齿轮、轴、蜗杆及螺栓、销钉等

●力学性能：
条件屈服强度 σ0.2 (MPa)：≥835
断面收缩率 ψ (%)：≥55
冲击韧性值 αku (J/cm2)：≥98
硬度 ：341～292HB

热处理规范：820～840℃油或温水淬火+400～500℃回火,油或水冷。
金相组织：1)调质处理:回火索氏体;2)渗碳后经淬火、低温回火:回火马氏体

20CrNi3A quenching is good, and can obtain the uniform intensity in the large section. After quenching and tempering, there is good comprehensive mechanical properties. Cutting process is good, cold deformation plasticity and welding medium. The formation of white sensitivity, high temperature tempering tempering brittleness. 20CrNi3A used as a high load working condition of gear, shaft, worm and bolt, pin etc.
- Mechanical properties:
Conditional yield strength (MPa = 835): 0.2
Section shrinkage (%): 55 PSI
The impact toughness value of alpha Ku (J/cm2): 98
Hardness:341 ~ 292HB
Heat treatment specification: 820 ~ 840 for oil or warm water quenching +400 ~ 500, oil or water.
Metallographic structure: 1) the quenching and tempering treatment: after the tempering of the rope's body; 2), after quenching, low temperature tempering: tempering martensite

值得一提的是，在宝钢、武钢下调10月份钢材价格的同时，部分钢厂则采取了限价的政策。9月14日，河北钢铁集团销售总公司发布通知称，鉴于目前京津区域建材市场现状，河北钢铁集团针对京津市场出台限价政策，对于低于限定价格销售的，本月将暂停甚至终止对其供货。

山东莱钢永锋钢铁也发出了类似的限价通知。根据通知，永锋钢铁对相关产品设定了最低销售价格，客户如果违反要求进行销售，将对客户予以停单三天处罚，并罚款1万—3万元。

据记者了解，目前北京地区的线材和螺纹钢均维持限价状态，市场价格暗降不多，暂时企稳，但出货情况并不理想。市场人士认为，短期内限价状态将继续维持，但随着资金压力增大，贸易商暗降现象或将逐渐增加。

It is worth mentioning that, in Baosteel, Wuhan Iron and steel prices in October down the same time, some steel mills have taken the price limit policy. September 14th, Hebei iron and Steel Group sales company issued a notice that, in view of the current situation of Beijing, Tianjin and regional building materials market, Hebei iron and Steel Group for the introduction of a price limit policy for the Beijing, Tianjin, and for the lower limit price sales, this month will be suspended or even termination of its supply.
Shandong also issued a notice of Laigang Yongfeng steel price similar. According to the notice, Yong Feng Steel on the relevant product set a minimum sales price, customers if the violation of the requirements of the sale, the customer will be suspended for three days and a fine of 10000 - 30000 yuan.
According to the reporter, at present Beijing area of wire rod and rebar were maintained limit state, market price Anjiang, temporarily stabilized, but shipments is not ideal. Market participants believe that the limit state in the short term will continue to maintain, but with the increase of the pressure of funds, trader Anjiang phenomenon or will gradually increase.
