According to Material Grades, SS400 steel is defined in JIS G3101 standard, which is a Japanese material standard for general structural usage, sheets, strips and rolled steel plates. They are also supplied as bars, flats and sections and excel in machinability and weld ability.
Advantages of JIS G3101 SS400:
Compared with other steel standard, steel products made of ss400 carbon steel is popular for proper tensile strength and toughness, good plasticity, welding performance and processing property. Steel plate thickness has wide range-from steel sheet to super heavy steel plate.
JIS G3101 ss400 Chemical Composition:
| Grade | Chemical Composition, % by weight | ||||
| C. max | Si. max | Manganese | P. max | S. max | |
| SS400 | - | - | - | 0.050 | 0.050 |
JIS G3101 ss400 Mechanical Property:
| Grade | Yield Strength min. | Tensile Strength | Elongation min. | Impact Resistance min.[J] | |||
| Thickness <16 mm | Thickness ≥16mm | Thickness <5mm | Thickness 5-16mm | Thickness ≥16mm | |||
| SS400 | 245 | 235 | 400-510 | 21 | 17 | 21 | - |
JIS G3101 SS400 Application:
SS400 steel plate and other steel grades product are applied to general structural constructions-bridges and ships, final product always supplied hot rolled.
