SS400 steel mechanical properties: SS400 steel tensile strength is expressed in Newton per millimeters and it must be at-least 400 N/mm2 (MPa) and maximum can be 510 N/mm2 (MPa). SS400 steel yield strength is minimum 205 to minimum 245 N/mm2 (MPa) depending on the thickness. SS400 steel yield strength for thickness below 16 mm is minimum 245 N/mm2 (MPa) whereas for higher gauges above 100 mm is minimum 205 N/mm2 (MPa). SS400 steel elongation varies with the ranges of thickness.  The minimum percentage ranges for SS400 steel elongation is 17% for thickness till 16 mm, 21% for thickness till 40 mm, and 23% for thickness greater than 50 mm.
