Although high-manganese steels may have desirable mechanical strength and corrosion resistance, machining and casting can be difficult. Alternatively, high-manganese steel parts may be fabricated to near-net shape parts using powder metallurgical processing, such as hot pressing and powder injection molding, thereby significantly minimizing or eliminating the need for further machining of fabricated parts. Hot pressing processes may comprise: loading a container with a plurality of particulates comprising a high-manganese steel; establishing a reduced pressure state in the container after loading the container with the plurality of particulates, and sealing the container to maintain the reduced pressure state therein and to afford a sealed container; placing the sealed container in a pressure vessel; heating the pressure vessel at a predetermined temperature while applying a predetermined pressure isostatically to an exterior surface of the sealed container with a pressurizing gas to consolidate the plurality of particulates into a densified part having a near-net shape; and removing the sealed container to expose a surface of the densified part.

Mooring chains used in offshore environments are typically formed from carbon steels due to their wear and fatigue resistance properties. Although carbon steels may exhibit robust mechanical properties, they are susceptible to corrosion, which can shorten the usable working lifetime of mooring chains, particularly in a seawater environment. Austenitic steels comprising high percentages of manganese may have comparable mechanical properties to the carbon steels commonly used in mooring chains, yet exhibit less susceptibility to corrosion. Austenitic steels suitable for use in mooring chains and other structures in contact with or exposed to a seawater environment may comprise: 0.4-0.8 wt. % C, 12-25 wt. % Mn, 4-15 wt. % Cr, a non-zero amount of Si
