Corrosion-resistant stainless steel chains

In standardised salt spray tests at iwis the new CF (Corrosion Free) stainless steel chains demonstrated outstanding corrosion resistance and excellent fatigue strength. With these characteristics, iwis corrosion-free chains offer outstanding results in corrosive environments, with water or steam, stringent cleaning regimes or extreme temperatures. They are typically used in the food industry, in filling and conveying applications and in packaging machinery.

The plates of the CF stainless steel chains have better precision blanking than conventional corrosion-free roller chains, increasing service life and reducing elongation through higher press-out forces. All rollers are seamless and therefore exceptionally impact-resistant at higher speeds, which ensures smooth, even chain operation. Seamless bushes  reduce initial stretch and allow customised length tolerances, resulting in greater positioning accuracy and speed, especially in dynamic cyclic operation. This is a major advantage in filling, conveying and packaging applications. On request, iwis can provide graphs of load–elongation data for all chains.

iwis CF stainless steel chains meet the requirements of ISO 606 (DIN 8187). They can be used in a temperature ranges from -80 to +150 °C. Various special-purpose lubricants are available to allow the chains’ use at high temperatures of up to 400 °C as well as low temperatures. In addition, various H1-approved lubricants for use in food processing and specially developed wax lubricant approved for food use is available. Conveyor chains with attachments can be produced at short notice.

In addition to the new CF stainless steel chains, iwis provides a full product range for all drive and conveying applications, which also includes precision and high-performance roller chains, conveyor chains, maintenance-free and corrosion-resistant chains, power and free conveyor chains, special-purpose conveyor chains, flyer chains, flat-top chains, modular belts, chains and accessories for agricultural machinery, and timing drives for the automotive industry.
