Weldability And Corrosion Properties Of Austenitic Stainless Steel And Low Alloy Steel Manufactured Using PM-HIP Method

Powder metallurgy with hot isostatic pressing (PM-HIP), which enables to densify powders in a furnace at high pressure and temperature is a newly developed manufacturing process for pressure retaining part in nuclear industry. It has advantages such as weld free near-net shape products, improved material properties for castings, short process time, saving in raw material costs, etc. EPRI have conducted several tests such as tensile test, impact test, chemical composition analysis on the manufactured samples for pressure retaining applications.

Powder metallurgy with hot isostatic pressing (PM-HIP) is a trending manufacturing technology for nuclear industry especially for small modular reactor (SMR) because it exhibits multiple advantages (e.g., near-net shape products, short process time, etc.). In this study, ASTM A988 STS 316L and ASME SA-508 Gr.3 Cl. materials for pressure retaining part were manufactured using PM-HIP method. Their mechanical properties, weldability, and corrosion characteristics were investigated.
