Corrosion resistant steel plate, as a new generation of advanced steel material, has 2-5 times of atmospheric corrosion resistance as ordinary carbon steel such as B750L structure steel for cold forming, and the longer the service time, the more prominent the corrosion resistance. Due to its characteristics of rust resistance, coating free, thinning and consumption reduction, labor saving and energy saving, corrosion resistant steel plate can be applied to steel structures exposed to the atmosphere for a long time, such as buildings, vehicles, bridges, towers, etc., and can also be used to manufacture structural parts such as containers, railway vehicles, oil derricks, seaport buildings, oil production platforms, etc.

B750L structure steel for cold forming, Q390B steel plate generally adopts the process route of refined material entering the furnace-smelting (converter, electric furnace-microalloying treatment-argon blowing-LF refining-low superheat continuous casting (feeding rare earth wire)-controlled rolling and controlled cooling. During smelting, The scrap steel is added to the furnace along with the charge and smelted according to the conventional process. After tapping, the deoxidizer and alloy are added. After the molten steel is treated by argon blowing, it is cast immediately. Rare earth elements are added to the steel, the Q390B steel plate is purified, and the content of inclusions is greatly reduced.

35SiMn steel chemical elements: C: 0.32-0.40, Si: 1.10-1.40, Mn: 1.10-1.40. The mechanical properties of 35SiMn steel: tensile strength 885 MPa; yield strength 735 MPa; elongation after fracture: 15; reduction of area: 45; impact energy: 47J. 35SiMn steel belongs to alloy quenched and tempered steel with good properties and can be used instead of 40Cr steel. After quenching and tempering, B750L structure steel for cold forming, 35SiMn steel has high static strength, fatigue strength, wear resistance, good toughness, good hardenability and medium plasticity during cold deformation.

The steel plate, steel pipe and other steel materials are the important material in the material engineers. Our company will provide the high quality the steel plate, steel pipe and other steel materials for you. We are exported the steel plate, steel pipe and other B750L structure steel for cold forming steel materials to the customers from USA, South America, Europe, Africa etc. If we can have the good cooperation together, you will be very welcome to be our agent in your local market. Let’s work together!

In addition to quality assurance, service is also important for the competition of steel suppliers. All the after-sales service personnel of the company have received professional training and assessment. The steel products supplied by our company enjoy the life-long quality problem replacement service. In the process of using our steel B750L structure steel for cold forming products, if there is any problem, just contact us in time, and our after-sales service personnel will look for countermeasures and solve the problem with you as soon as possible.
