Stainless steel wire for rod rigging
Keywords: Sandvik Steel, Stainless steel
A new stainless steel grade, specially developed for use on mast rigging on ocean going and high performance yachts, has been produced by Swedish steelmaker Sandvik Steel.
Called Sandvik Sanrig 80, the new material is described as a fully austenitic stainless alloy designed to give the highest possible fatigue and tensile properties combined with corrosion resistance in seawater (Plate 1).

type pictured from X-yachts A/S in Denmark are the target market for Sandvik
Steel's new Sanrig 80 Rig Rod
Sandvik Sanrig 80 rig rod is currently available in a size range from 4.4mm diameter up to 17.9mm diameter. It is stated to have a tensile strength of between 1,400 and 1,500 Mpa, depending on size and a breaking strength from 2,324kgs at the smallest size up to 35,895kgs at 17.9mm diameter. It is produced in the form of cold drawn, degreased and polished wire and is supplied in straightened lengths or in coils.
Any material subjected to load cycles, which individually do not exceed the breaking strength of the material, can be affected by metal fatigue. The high tensile strength of Sandvik Sanrig 80 is believed to increase its fatigue strength and reduce the risk of fatigue failure.
The other key property is corrosion resistance. Tests simulating seawater attack have reportedly concluded that the pitting corrosion resistance of Sandvik Sanrig 80 rig rod satisfies the application requirements and equals the performance of other material grades available on the market.
A technical data sheet has been produced on the new grade and is available from Sandvik Steel.
