BlueScope Steel Australia:What those grade names really

Jan 14, 2002 · However, the difference between a transverse bend (across the plate) and a longitudinal bend (along the plate) is greater in the HA250 XLER® coil plate than in the 3678-250 XLERPLATE® grade. This is because the plate mill process tends to involve more cross rolling than the hot strip mill. Buy Hot Rolled Carbon Steel Plate,Carbon Steel Sheet 3 carbon steel plate 3mm thick application:construction,machinery manufacturing, container manufacturing, shipbuilding, bridge construction. Can also be used to manufacture a variety of containers, the furnace shell, furnace plate, bridge and vehicle static steel plate, low alloy steel plate,shipbuilding plate, boiler plate, pressure vessel plate, pattern plate, tractor parts, automobile Important Machining Factors of Carbon Steels Mar 22, 2006 · Knowledge of the factors that contribute to the machinability of carbon steels is critical for shops making complex precision engineered parts in high volumes. Chemistry, microstructure and mechanical properties as a result of cold work are three of the most important factors influencing the machining of these steels.
