When standard carbon-steel chains corrode, seize, or contaminate your process, you need a material upgrade that holds up without constant maintenance. Engineers, fabricators, and serious DIYers who work in wet, chemical, or food-adjacent environments rely on 304 stainless steel roller chain to keep drives running cleanly and reliably over the long term.
This roller chain is manufactured from 304-grade stainless steel throughout — plates, pins, bushings, and rollers — delivering inherent corrosion resistance without surface coatings that can flake or wear away. Available in ANSI/ISO simplex sizes 04C, 05B, 06B, 06C, 08A, 08B, 10A, 10B, 12A, 12B, 16A, 16B, and 20A, with cut lengths of 1 m (approx. 3 ft) and 1.524 m (approx. 5 ft) to suit a wide range of drive spans.
Typical use cases include conveyor systems in food processing or washdown environments, replacement drive chains on agricultural equipment exposed to moisture, power-transmission runs on marine or outdoor machinery, and custom DIY automation builds where stainless steel roller chain for corrosion resistance is a hard requirement.

Match the chain size to your sprocket's pitch and roller diameter. The number in the designation (e.g., 06, 08, 10) relates to the pitch in increments of 1/16 inch for ANSI sizes, while the letter (A or B) indicates the ISO series. Check your sprocket's datasheet or measure the existing chain pitch — the distance between pin centers — and select the matching size from the variant options above.
304 stainless steel roller chain has lower tensile strength than hardened carbon-steel chain of the same pitch, so it is best suited for light-to-medium duty drives where corrosion resistance is the priority. For heavy shock loads or very high-speed drives, verify the working load against the chain's rated tensile strength for your selected size before installation.
304 stainless steel offers strong resistance to rust and oxidation in most wet, humid, and mildly corrosive environments. It is not fully immune to chloride-induced pitting (e.g., saltwater immersion), but it significantly outperforms carbon-steel chain in washdown, food-processing, and outdoor applications. For highly aggressive chloride environments, 316 stainless may be more appropriate.
Yes — stainless steel roller chain conforms to the same ANSI/ISO simplex dimensional standards as carbon-steel chain, so it will seat correctly on any sprocket with a matching pitch and roller diameter. There is no need to replace your sprockets when switching to stainless chain.
Measure your required chain run (center-to-center distance plus wrap around both sprockets) and add a small allowance for the connecting link. The 1 m (≈3 ft) length suits shorter drives and replacement sections, while the 1.524 m (≈5 ft) length covers longer spans and reduces the number of joins needed. If your required length falls between the two, order the longer option and trim to fit.
Use a stainless steel connecting link (master link) that matches your chain size and pitch. Standard carbon-steel connecting links are not recommended in corrosive environments as they will become the weak point in an otherwise stainless assembly. Stainless connecting links for ANSI/ISO simplex sizes are widely available from industrial fastener suppliers.
Apply a food-grade chain lubricant or a stainless-compatible oil at regular intervals, especially in wet or high-cycle applications. Avoid petroleum-based greases that can attract contaminants in food environments. In very low-speed or intermittent-duty applications, a light machine oil applied to the inner link plates and rollers is sufficient.
