How to remove rust of a242 type 1 steel mill

The company has a242 type 1 steel mill advanced production equipment and machining technology, excellent marketing team and domestic regional channel partners, and sound management plan for product market development and after-sales service. After years of cooperation experience a242 type 1 steel mill, we have accumulated a large number of customers at home and abroad, and won unanimous praise.

Weathering steel a242 type 1 steel mill 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.

Cold rolled coil products a242 type 1 steel mill have accurate size and uniform thickness, and the thickness difference of coil is generally less than 0.01-0.03mm or less, which can fully meet the requirements of high precision tolerance. The surface quality of cold rolled products a242 type 1 steel mill is superior, and there are no defects such as pockmarks, pressing iron oxide scale and so on, which often appear in hot rolled coils. According to the requirements of users, coils a242 type 1 steel mill with different surface roughness can be produced (glossy surface or matte surface, etc.).

The composition characteristics of low alloy high strength steel are low carbon ≤0.20%, low alloy, and total alloying elements is less than 3%. The low carbon content is to meet the process performance requirements of a242 type 1 steel mill, low alloy high strength steel for engineering structural parts such as plasticity, toughness, weldability and cold deformation; adding a small amount of alloying elements (mainly Mn) to achieve the purpose of improving mechanical properties. Mn not only has a significant strengthening effect on ferrite, it can also reduce the cold brittle temperature of steel, increase the amount of pearlite in the steel, and further improve the strength.

SA516Gr.70 steel chemical composition (%):C≤0.30, Mn: 0.79-1.30, P≤0.035, S: ≤0.035, Si: 0.13-0.45. ASME SA516Gr.70 material is a carbon steel grade for medium and low temperature pressure vessels. In order to meet the different requirements of users and facilitate production management, the S and P requirements of steel grades are divided into three levels of Ⅰ, Ⅱ and Ⅲ. a242 type 1 steel mill, SA516Gr.70 pressure vessel steel is used to improve the notch toughness of welding steel plates for pressure vessels.
