SSAB product range describes manufacturing dimensions; individual stock and shipping availability are confirmed for your requested lot.
Hardox® 400 is specified by Brinell hardness and SSAB product guarantees. Typical mechanical values remain reference data.
SSAB performs Brinell hardness tests according to EN ISO 6506-1. For thin sheet below 2.5 mm, hardness is derived from guaranteed tensile strength. For impact testing, confirm the required temperature, sample size and acceptance conditions with the order.
