Available in marine grade tempers H116, H321, H323 to spec ASTM B928. This is an excellent alloy, which is primarily used for its corrosion resistant properties. With possessing good welding capabilities for fabricating vessels it is a good standard engineering alloy. This alloy is commonly used in Europe and Asia.
Available in marine grade tempers H116, H321; to spec ASTM B928. Tempers O, H112, H32; to spec ASTM B209. The marine grade alloy is very good at inter granular corrosion and possess better welding and forming properties. This alloy is commonly used in North America.
The alloy is most commonly used where excellent forming ability is required and is available in O, H112, H32, H34; to specification ASTM B209 Tempers. It serves as the manufacturing material for large pressure vessels and certain marine fabricated products.
It is an alloy possessing good strength and welding ability, which is also easy to form and fabricate. This alloy is not considered a true marine alloy.
It is a heat treated alloy possessing higher strength and is used in many general engineering applications. This alloy is also not considered as true marine alloy.
