AISI 316 Stainless Steel Guarantee
Rough surface finishes on stainless steel, promote tea staining. This is the brown spotting seen on the surface of any stainless steel which has been oxidized by salt water or salt in the air.
THE SMOOTHER THE SURFACE FINISH, THE BETTER.
A surface roughness (Ra) below 0.5 micrometre is strongly recommended. The lower the number the better. For example, a 0.1 is five times better than a 0.5 micrometre.
Typically, Proceans branded AISI 316 products sold exclusively by Whitsunday Discount Marine are polished to 600 grit or 0.1 micrometre. Your premium quality guarantee.
