Abstract
Results are presented of an investigation on the production of stainless steel strips, from the atomized powder AISI 316L. Compacting rolls, 300mm in dia. and 336mm long, are of the horizontal type. The effect of the roll gap, roll speed and feed rate of powder on the quality and output of green strips are described. To prevent the side flow of powder during the rolling, a side plate is set on the rolls. It is found that the use of the plate is effective not only in producing a sound green strip but also in reducing the powder loss. The green strip is cold re-rolled 15%, and then sintered, re-cold rolled and annealed. Sintering and annealing are carried out in a vacum (1×10-5mmHg). Mecanical properties of the fully processed strip are comparable with those of the conventionally produced material.
