The difference between low alloy high strength steel plate and carbon steel plate, EN steel grade S355JR plates:(1) Strength difference between low alloy high strength steel plate and carbon steel plate:The strength of low alloy high strength steel plate is higher than that of carbon steel plate;(2) Hardness difference between low alloy high strength steel plate and carbon steel plate:The hardness of low alloy high strength steel plate is higher than that of carbon steel plate;(3) Usage difference between low alloy high strength steel plate and carbon steel plate:The application range of low alloy high strength steel plate is wider than that of carbon steel plate.

Cold rolled EN steel grade S355JR plates 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 EN steel grade S355JR plates 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
