Stainless Steel: S304 (1.4301):

Marine shaft material for water, grease, or oil lubrication offering fair resistance to corrosion and moderate wear properties.

Stainless Steel: S431 (1.4057):

A high strength stainless steel for use in situations where the shaft torque and power dictate that the use of mild steel is not possible, offers moderate resistance to corrosion.

Stainless Steel: S316 (1.4401/1.4436):

Traditional marine shaft material for water, grease, or oil lubrication offering good resistance to corrosion and good wear properties.

Stainless Steel: 17/4ph (1.4542):

A martensitic, chromium-nickel-copper precipitation hardening stainless steel used for applications requiring high strength and a moderate level of corrosion resistance.

Duplex F.51 (1.4462):

A modern high strength stainless steel alloy offering excellent resistance to corrosion with outstanding wear properties, particularly useful for high speed, and high power applications where smaller shaft diameters are desirable to reduce drag from underwater hardware.

Super Duplex F.55 (1.4501):

Another modern Super-high strength stainless steel alloy offering excellent resistance to corrosion with outstanding wear properties, particularly useful for high speed, and high power applications.
