熱處理規范：820～840℃油或溫水淬火+400～500℃回火,油或水冷。
金相組織：1)調質處理:回火索氏體;2)滲碳后經淬火、低溫回火:回火馬氏體

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.

值得一提的是，在寶鋼、武鋼下調10月份鋼材價格的同時，部分鋼廠則采取了限價的政策。9月14日，河北鋼鐵集團銷售總公司發布通知稱，鑒于目前京津區域建材市場現狀，河北鋼鐵集團針對京津市場出臺限價政策，對于低于限定價格銷售的，本月將暫停甚至終止對其供貨。

山東萊鋼永鋒鋼鐵也發出了類似的限價通知。根據通知，永鋒鋼鐵對相關產品設定了最低銷售價格，客戶如果違反要求進行銷售，將對客戶予以停單三天處罰，并罰款1萬—3萬元。

據記者了解，目前北京地區的線材和螺紋鋼均維持限價狀態，市場價格暗降不多，暫時企穩，但出貨情況并不理想。市場人士認為，短期內限價狀態將繼續維持，但隨著資金壓力增大，貿易商暗降現象或將逐漸增加。

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.
