About JIS G 3115 SPV 355 steel Mechanical Property, different thickness has different property, such as:
When thickness is below 16mm, Min Yield is 355 Mpa, Tensilmie is 510-650 Mpa.
When thickness is between 16mm to 40mm, Min Yield is 345 Mpa, Tensilmie is 510-650 Mpa.
When thickness is between 40mm to 60mm, Min Yield is 335 Mpa, Tensilmie is 510-650 Mpa.
When thickness is between 60mm to 100mm, Min Yield is 315 Mpa, Tensilmie is 490-630 Mpa.
When thickness is between 100mm to 150mm, Min Yield is 295 Mpa, Tensilmie is 480-630 Mpa.
When thickness is between 150mm to 250mm, Min Yield is 280 Mpa, Tensilmie is 470-630 Mpa.
However, there are also differences between each other. The same is that, the Min Elongation is 20%, the Min Impact Energy at -20°is 27 KV J, at 0°is 34 KV J, at 20°is 40 KV J.
