Continuous rolled steel plates and single rolled steel plates Steel API 5L Grade B (L245) PSL1 Plate are often used in many industries. Although the appearance of these two steel plates is very similar and they are same steel grades, in some respects, they belong to two different plates. Because the continuous rolled steel plate is made of strip steel by uncoiling, leveling and shearing, its Steel API 5L Grade B (L245) PSL1 Plate comprehensive mechanical properties are not as good as the single rolled steel plate, so some important occasions would choose single rolled steel plate but not continuous rolled steel plate.In recent years, in line with the development trend of iron and Steel API 5L Grade B (L245) PSL1 Plate steel industry at home and abroad, we have accelerated the transformation of development mode, promoted structural adjustment, and formed a rich product series of medium and thick plates, hot rolled steel coils, profiles, steel pipes, etc., which Steel API 5L Grade B (L245) PSL1 Plate are widely used in automobiles, long-span bridges, railways, machinery, ocean and so on fields. Meanwhile, we also provide deep processing for the steel materials.Tempering the important Steel API 5L Grade B (L245) PSL1 Plate welding structure often use high temperature tempering to remove residual weld stress. Classification: high temperature tempering above 400 ℃, medium temperature tempering 250 ~ 400 ℃, low temperature tempering 150 ~ 250 ℃, Quenching +Tempering is improve Steel API 5L Grade B (L245) PSL1 Plate strength, plasticity and toughness.When phosphorus, copper, chromium, nickel and other trace elements are added to the steel, Steel API 5L Grade B (L245) PSL1 Plate, a dense and strong adhesive protective film will be formed on the steel surface, which will prevent the corrosion from spreading and developing inward, and protect the substrate under the rust layer, so as to slow down the corrosion rate. The amorphous spinel oxide layer of about 50 μ m ~ 100 μ m thickness formed between the rust layer and the substrate is compact and has good adhesion with the substrate metal.Before delivering our hot rolled plate product we apply various tests to check the quality of carbon steel Steel API 5L Grade B (L245) PSL1 Plate plates such as- mechanical test, chemical test, hardness test, toughness test, eddy current test, impact test, micro test, flaring test, flattening test, etc. We are provided best packing for structural steel plates to avoid rust. Our after-sales service team will contact you if you have any question.
