Stainless Steel Grade 316 is very corrosion resistant (more so than 304), has slightly less strength, is annealed but is more stiff and slightly more difficult to use than the 304.
Because your wire becomes your clamp, we recommend stainless steel wire because of its strength and durability, which results in your clamp being strong and durable. Although, the ClampTite tool will work with all wires, the stainless steel wire is the strongest and most durable. By simply cutting the wire to the length you need, you can have a clamp of any size. Remember you need to match the wire to your project needs.
