Q420qENH material nomenclature Q

- represents the yield strength of the material with a capital letter Q

420 - represents the yield strength value of the material, The strength grade

used to distinguish the material is q--where q is the bridge

E that represents the bridge--the quality grade of the material (-40°C impact)

NH--is the abbreviation

of the capital letter of Chinese weather resistanceWe will also see Q420qENHZ15, Q420qENHZ25, Q420qENHZ35 such grades,
