Material Types
- Bronze resists corrosion caused by brine, gases, and sulfite solutions. It is non-magnetic, and non-sparking and has a smooth finish.
- Carbon steel is steel where the main alloying constituent is carbon. As carbon
content rises, steel becomes harder and stronger, with a lower melting point,
but also becomes less ductile.
- Cast Iron is a strong, hard, brittle, non-ductile iron-carbon alloy.
- Copper is both ductile and malleable, conducts heat and electricity well, is resistant to corrosion, and tarnishes easily to form a protective layer of brownish-black copper oxide coating.
- Galvanized steel or iron can be coated with a thin layer of zinc. This protects the underlying material from corrosion and provides rust-resistance. It remains ductile over long work periods. Galvanized steel usually has a higher breaking strength than stainless steel.
- Iron is strong, non-flexible, magnetic, and metallic.
- Monel, also known as nickel-copper alloy 400, is durable and resists heat and corrosion and is slightly magnetic. This material is especially suitable for use near salt water.
- Nickel is corrosion-resistant, ferromagnetic, maintains much of its strength at high temperatures, and stays tough and ductile at low temperatures.
- Stainless Steel resists scaling and corrosion, but is weaker than plain steel.
- Stainless Steel 302/304, also called stainless steel 18-8 (18% chrome and 8% nickel), is a common grade that is corrosion resistant, has good strength and can withstand high temperatures. It is used for yachting ropes and control cables.
- Stainless Steel 305 is slightly more corrosive-resistant than 302. It's largely non-magnetic and suitable for use in the aeronautical and navel industries.
- Stainless Steel 316 is more corrosion-resistant than 304, due to the addition of molybdenum in the alloy. Sometimes 316 is called "marine grade stainless steel" because of its resistance to chloride corrosion.
- Steel, also called plain steel, or carbon steel, is one of the strongest wire rope materials, but it is less corrosion-resistant than stainless steel. It has increased rust-resistance over wrought iron.
