The thickness range of steel coil is from 1.2mm to 25.4mm, the thickness of steel plate can achieve to 700mm from 4.5mm, The supply capacity per year is about 8,900,000 tons steel plate/coil according to EN10025,EN10028,ASTM A36,ASTM A131, JIS G3101,JIS G3106 gbt 11251 45crnimova steel Steel plate - Sunny SteelQuenching and tempering is a two-step heat treatment process. In the quenching step of this process, steel is heated to a temperature between 1,500-and 1,650-degrees Fahrenheit, then rapidly cooled with water. In the tempering step, the steel is then re-heated to a below-critical temperature between 300 and 700 degrees and air-cooled. gb t 3077 50crni alloy structure steel - Frez -Mould and 12crni3 seamless pipe-Truhlarstvi Hubeny Steel gb t 3077 50crni alloy structure steel.
