Gear Steel
We stock DNV certified premium quality Gear Steels Buderus 6587 ISO-B in various dimensions and deliver the same as sawn disks.
DNV certification confirms that:
“Discs sawn from Random length bars using Buderus Edelstahl
ISO-B technology ensures consistent properties as required by
DNV high grade, for rounds up to Dia 1450mm.”
Sizes smaller than 500mm are BG annealed, and bigger dimensions are stocked quenched and tempered with hardness identical to the annealed material.
With proper agreements, we can stock material based on customer specifications so that you can just dial in your requirements for rapid delivery
