In terms of service, our service is a "one-stop" way of working. We have our own KF32 hull structural steel sheet processing plant and pretreatment plant, pretreatment of ship steel (shot blasting, derusting, painting). Technical parameters of steel plate and profile steel surface pretreatment production line. We can also let customers enjoy our other pretreatment services, such as KF32 hull structural steel sheet cutting, welding, drilling, galvanizing, etc., at the lowest cost.
Generally, the production process of KF32 hull structural steel sheet seamless steel tube can be divided into cold rolling and hot rolling. The production process of cold-rolled seamless steel tube is generally more complicated than that of hot rolling. The tube blank must be first rolled by three rolls, and then be subject to sizing test and cutting after extrusion. Then enter the annealing process. In appearance, the cold-rolled seamless steel tube is shorter than the hot-rolled seamless steel tube, and the wall thickness of the cold-rolled seamless steel tube is generally smaller than that of the hot-rolled seamless steel tube, but the surface looks brighter than the thick wall seamless steel tube, the surface is not too rough, and the diameter is not too much burr.
Corrosion resistant steel prices are generally higher. What are the applications of KF32 hull structural steel sheet, corrosion resistant steel? First, the corrosion resistant steel can be used in chemical containers, such as furnaces. Some chemical products have strong corrosivity and need steel with excellent corrosion resistance, otherwise they will be easily corroded. Second, the corrosion resistant steel can be used for sewage pipelines. Industrial sewage pipelines need to discharge a large amount of wastewater, which may contain harmful substances.
Corrosion resistance of stainless steel mainly owes to the formation of a very thin, adhesive and translucent chromium oxide film on the surface of stainless steel. Once the film is damaged, the chromium in the stainless steel will react with oxygen in the atmosphere to restore the film quickly. At the same time, the mechanical damage can also generate a protective film quickly to prevent the KF32 hull structural steel sheet, stainless steel from corrosion.
KF32 hull structural steel sheet, No. 20 steel belongs to high-quality carbon steel.No. 20 steel means steel with an average carbon content of 0.20%;The thermal conductivity of No. 20 steel at 315℃ is 48 W/m℃;No. 20 steel is generally not quenched, the general treatment method is carburizing or normalizing;The yield strength of No. 20 steel is not less than 250MPa;The tensile strength of No. 20 steel is not less than 420MPa;Elongation of No. 20 steel is not less than 25%;The reduction of area is not less than 55%;The density of KF32 hull structural steel sheet and No. 20 steel is 7.85kg/cm3
