SGH440 is the base material SPH440 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 SGH440 is for commercial use of high strength class
SGH440 steel Applicable thickness is 1.6mm or over up to and including 6.0mm
SGH440 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
SGH440 steel surface finish for non-alloyed coating : R (Regular spangle) and Z(Minimized spangle)
SGH440 steel surface chemical treatment are: C(Chromate treatment), P(Phosphate treatment), NC(Chromate-free treatment), NP(Chromate-free phosphate treatment), M(Untreated)
SGH440 steel tensile test characteristics:
yield strength :should be not less than 335MPa
tensile strength should be not less than 440MPa
Elongation should be not less than 18%
