Our Process for PM Stock

Griggs Steel manufactures PM stock using the proprietary Crucible Particle Metallurgy process, a form of powder metallurgy. This process involves pouring the molten alloy through a spray nozzle and atomizing it to produce tiny droplets of steel that quickly cool into a fine powder, stored in sealed and decontaminated capsules. The powder is then subjected to hot isostatic pressing (a combination of high pressure and near-melting point temperature) to compact it, producing a fine-grained, homogeneous bulk structure with a uniform distribution of carbides and little to no precipitation of alloying elements.
