SGH540 is the base material SPH540 which are equally coated on both surfaces by hot dip zinc coating process. The composition by mass fraction is 97% or over zinc (provided that the aluminium content is usually 0.3% or less). The Application of SGH540 is for commercial use of high strength class
SGH540 steel Applicable thickness is 1.6mm or over up to and including 6.0mm
SGH540 steel coating shall be classified into 2 types: non-alloyed coating and alloyed coating. Non alloyed coating mass are: Z06/Z08/Z10/Z12/Z14/Z18/Z20/Z22/Z25/Z27/Z35/Z37/Z45/Z60, Alloyed coating are: F04/F06/F08/F10/F12/F18
SGH540 steel surface finish for non-alloyed coating : R (Regular spangle) and Z(Minimized spangle)
SGH540 steel surface chemical treatment are: C(Chromate treatment), P(Phosphate treatment), NC(Chromate-free treatment), NP(Chromate-free phosphate treatment), M(Untreated)
SGH540 steel tensile test characteristics:
yield strength :should be not less than 400MPa
tensile strength should be not less than 540MPa
Elongation should be not less than 16%
