*Why 316 Grade / A4 Stainless Steel?
The Monobolt^® range has now been extended through the addition of a 316 Grade / A4 stainless steel Monobolt^® suitable for applications in marine and hostile environments where 304Cu Grade / A2 stainless steel Monobolt^® may not be the most suitable solution.

316 Grade has a higher nickel content than other alloys and contains molybdenum. The molybdenum allows the material to deliver enhanced corrosion resistance particularly to pitting and crevice corrosion. Additionally this alloy lends itself to both forming and welding without excessive cracking. For this reason, it is particularly good for assemblies in marine and hostile environments.
