PM HIP NNS process to manufacture high-grade materials

02 May 2019

PM HIP NNS process (Powder Metallurgy – Hot Isostatic Pressing – Near Net Shape process) is a state-of-the-art technology to manufacture metal products made of high grade materials, such as, stainless steels and super alloys.

Shimoda has been developing this new process to manufacture fittings by PM HIP NNS process in collaboration with Metal Technology Co. Ltd. (MTC) who specializes in HIP treatment. MTC’s HIP unit, Giga HIP, is the world’s largest working zone (2,050mm dia x 4,200mm height).

The duplex stainless steel flanges HIPed by the Giga HIP unit are qualified by NORSOK standard of Norway as: QTR No.: QTR30-01; Material: ASTM A988 S32505, Ferritic / Austenitic Stainless Steel, Type 25Cr Duplex; Products: Flange; Process: HIP process; Thickness: up to 184.2mm; qualified date: March 19, 2019.
