Abstract

The conventional way to manufacture stainless steel fittings is heavily energy consuming due to the different manufacturing steps (forging, rolling, sometimes cold drawing, followed by machining) and generates a high percentage of scrap during the machining of the inner hole and outside features.

Using the MMS-Scanpac® process (agglomeration, pre-compaction, low-temperature sintering, high velocity adiabatic re-striking and final sintering ) allows to make the same products with a better yield (76% instead of 33%), huge energy savings (up to 13kWh/kg), and a shorter supply chain. This eco-friendly route has been used to make products with properties equal or better than forged products which are described in the present paper and which are approved for pressure vessel usage
