Sale the 40mm thickness hardox 400 specification

P275NH normalizing can weld refined grain steel. Fine grain steel HARDOX 400 specificationis understood to be steel with ferrite grain size of 6 or finer after testing according to EURONORM103 standard. Executive standard: EN10028-3, number: 1.0487. P275NH is non-alloy quality steel for pressure equipment. P275NH steel plate has good plasticity, toughness, cold bending performance and welding performance.

The quality grade symbols of Q235 steel plate are A, B, C and D respectively. Different grades represent different impact temperatures. HARDOX 400 specification, Q235A is not required for impact toughness test; Q235B is required for impact toughness test at room temperature (20 ℃); Q235C is required for impact toughness test at 0 ℃; Q235D is required for impact toughness test at - 20 ℃. For the above-mentioned B, C and D grade steels, Akv ≥27J is required under different temperature requirements. At different impact temperature, the impact value is also different.
