Two days ago, a friend left a message to Xiaobian, asking what level of reinforcement is hrb400? For the small editors who have been in the steel market for many years, this problem is naturally very simple, but for the friends who have just entered the steel market, it makes them difficult.
So what level of reinforcement is hrb400? HRB400 steel bar, also known as three-stage threaded steel, is a kind of hot-rolled ribbed steel bar. HRB400 is the brand of this steel bar. Steel brand, also known as steel product brand, generally uses Chinese phonetic alphabet, chemical element symbols and Arabic numerals to express the name, use, characteristics and process of steel products.
Speaking of this, we also briefly introduce the third-grade threaded steel. Threaded steel belongs to small steel, which is mainly used for the skeleton of reinforced concrete building components. Some mechanical strength, bending deformation and welding properties are required in use. The raw material for producing threaded steel is carbon structural steel or low alloy structural steel treated by sedation melting, and the finished steel bar is delivered in hot rolling, normalizing or hot rolling state.
About HRB400 is the introduction of several grades of steel bar, it is temporarily over. If you want to know more about steel, you should pay more attention to Jinan Jiazhengqiang Steel Co., Ltd., which will also bring you more steel knowledge.
