Ferralium® 255 super duplex stainless steel (UNS S32550, Alloy 255, DIN 1.4507, ASTM F61) has close to ideal bolting properties, so leading fastener manufacturers now produce Ferralium® 255 nuts and bolts to most standard design and size specifications.
Those properties make it well suited to fasteners and fastening assemblies:
- High tensile strength
- Excellent ductility and notch toughness
- Good anti-galling properties
- Outstanding corrosion resistance
Arnold Wragg (Bolts & Nuts) Limited of Stannington, Sheffield, one of the largest producers of corrosion resistant fasteners in the UK, offer a comprehensive range of standard fasteners in Ferralium® 255, either from stock or on early delivery, and will produce customers' own special designs depending on quantity and form.
Alongside our normal production range of black, hot rolled bar in rounds and hexagons, we supply bright bar in diameters from ½" upwards.
