Cold rolled API 5L PSL1 X42, X56, X60, X70 steel coil steel sheet can be produced by two high mill, four high reversing mill, multi high reversing mill and tandem cold mill. Although there are still only two work rolls in four high and multi high rolling mills, each work roll is supported by one or more large diameter backup rolls, which can prevent deflection of work roll. As a result, wide and thinner API 5L PSL1 X42, X56, X60, X70 steel coil steel plates can be produced. For example, 20 high mill can produce as thin as 0. 001 mm sheet, but the two high mill can only produce as thin as 0. 35mm sheet
Hardness comparison between Q345B steel and NM450 steel: wear resistant steel for construction machinery requires high wear resistance, high toughness, impact resistance, easy welding, easy forming and other high-performance characteristics. The main index of wear resistance is the surface hardness. The higher the hardness, the better the wear resistance. Compared with API 5L PSL1 X42, X56, X60, X70 steel coil, Q345B steel, the hardness of NM450 steel is only increased 3 times, but the average service life is increased 6-8 times under the same working conditions.
