how hard is S890QL steel equivalent

Spring steel has good fatigue strength and can be restored to its original state after repeated use, without deformation, because the spring has good ductility and can be changed back to the original state no matter how long it is stretched. S890QL steel equivalent, Spring steel has good elasticity. Spring steel can not only be made into springs, but also be processed into swords, which requires good elasticity. The tensile strength of spring steel is good, it will not break and can be recovered under the condition of tensile limit.Cold rolled S890QL steel equivalent 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 S890QL steel equivalent 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 sheetAdvanced typical figures and typical deeds are the embodiment and symbol of S890QL steel equivalent enterprise spirit, outstanding ideas and vivid images, with strong demonstration, radiation and transmission effect. Without distinctive typical characters, there is no unique enterprise culture. In carrying out the construction of enterprise culture, the advanced enterprise culture should be typified.
