What is Sintering and Hot pressing? - Meetyou Carbide
The densifiion process of the alloys produced by the two production methods was compared. From the alloy density–sintering time curve, it can be seen that the sintering process takes 1-2 hours to complete, and it takes only 3 to 10 minutes for hot pressing.
The process was originally used solely for making high quality steel, such as those used for machine tools and spring steel, as it gave more precise control over the composition. Today, however, it is also employed in making more widely used steels, including alloy and stainless grades as well as some special carbon and low-alloy steels.
