12B-3 Corrosion-Resistant Roller Chains According to DIN 8187 (B-Series)
12B-3 corrosion-resistant roller chains (3/4″ × 7/16″), also known as corrosion-protected or anti-corrosion chains, are a special type of triplex drive chains. They have the same dimensions as standard roller chains according to ISO 606 (DIN 8187), meaning they belong to the European B-series.
The chains consist of outer links with pins and inner links with bushes, on which freely rotating rollers are mounted. The chains are made of steel with a special surface treatment that provides enhanced corrosion resistance. The specific method of corrosion protection (such as galvanizing or nickel-plating) varies by chain type and manufacturer.

Chains Fields of Use
12B-3 corrosion-resistant roller chains according to DIN 8187 are intended for applications in environments with an increased risk of corrosion, such as humid areas, outdoor operations, or other environments where standard chains do not provide sufficient corrosion resistance.
Typical fields of application include the food industry, agriculture, chemical industry, or wastewater treatment plants.
They are most commonly used as drive chains but can also be fitted with attachments or other auxiliary components for material handling and lifting applications.
Chains Material
Steel with a special surface treatment.
