A2 or A4 Stainless Steel

Deciding whether to use A2 or A4 Stainless for your job is a key decision in your purchase. The following illustrates a general rule of thumb.

A2 Stainless Steel
A2 Stainless Steel is suitable for most non-saltwater marine domestic applications. Particularly recommended for use in oak.
A4 Stainless Steel
A4 has a far greater resisitance to salt water corrosion. The rough rule of thumb within the marine industry is A2 above the waterline, A4 below. In general however, A4 is the best grade in all salt water applications.
