ANSI Single Pitch SS Chain

Tsubaki ANSI Single Pitch SS Chain

All basic components of this chain are made of Stainless Steel SUS304 (except the spring clips, which are made of SUS301). This chain can be used in special environments such as underwater, acidic and alkaline applications. It can also be used in high and low temperatures
(-20°C to +400°C). SUS304 is only marginally magnetic, which is a result of the cold-forging process. For details on corrosion resistance, please refer to our Corrosion Resistance Guide.
