SGH400 is the base material SPH400 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 SGH400 is for commercial use of high strength class
SGH400 steel Applicable thickness is 1.6mm or over up to and including 6.0mm
SGH400 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
SGH400 steel surface finish for non-alloyed coating : R (Regular spangle) and Z(Minimized spangle)
SGH400 steel surface chemical treatment are: C(Chromate treatment), P(Phosphate treatment), NC(Chromate-free treatment), NP(Chromate-free phosphate treatment), M(Untreated)
SGH400 steel tensile test characteristics:
yield strength :should be not less than 295MPa
tensile strength should be not less than 400MPa
Elongation should be not less than 18%
