Type 304 stainless steel is the standard alloy for use in wire rope and cable. It has about the same strength as galvanized wire rope or cable but is much more corrosion resistant. It can be used in most industrial atmospheres and has acceptable corrosion resistance when used in marine and salt water.
316 grade stainless steel is the standard high-corrosion-resistant steel for wire rope and cable. It is resistant to many chemicals in the pulp and paper, photographic, food processing, and textile industries. Type 316 stainless steel wire rope has the best pitting resistance in marine and salt water, and can be used in temperatures up to 900 degrees Fahrenheit.
The vast majority of wire rope specifications are designated with 316 or 304 (and sometimes 302 grade). The basic difference is in the elements that comprise the alloy itself—and 316 stainless wire rope is known to be more corrosion-resistant than 304.
The 6x19 stainless steel wire rope is made up of six strands of between 16 and 26 wires per strand for additional wire rope strength and durability. Also available in USA-made.
