Diamond SS Chain

1. Standards & Compliance

SS roller chains are typically manufactured according to:

• ANSI (American Standard e.g., ANSI B29.1)

• ISO (ISO 606)

• DIN (DIN 8187 / 8188)

• BS (British Standard)

Common series:

• ANSI Series (e.g., #40SS, #50SS, #60SS)

• BS / European Series (e.g., 08BSS, 10BSS, 12BSS)

2. Material Specifications

Standard Material Grades

Common Stainless Steel Grades

• SS304 General corrosion resistance, food industry use

• SS316 Superior corrosion resistance (marine, chemical)

• SS420 Higher strength and hardness (martensitic)

3. Dimensional Specifications (Example: ANSI #40 SS Chain)

Dimensions vary depending on chain size and series.

4. Mechanical Properties

Note: SS chains have lower load capacity compared to carbon steel chains.

5. Surface Finish

• Natural stainless finish

• Electropolished (for food/pharma applications)

• Passivated surface

• Non-plated (corrosion resistance inherent to material)

6. Lubrication

• Can operate dry in clean environments

• Food-grade lubricants recommended

• Periodic lubrication improves service life

• Self-lubricating variants available (with polymer bushings)

7. Applications

SS Roller Chains are commonly used in:

• Food processing conveyors

• Beverage industry

• Pharmaceutical machinery

• Marine environments

• Chemical plants

• Water treatment systems

8. Advantages

• Excellent corrosion resistance

• Suitable for washdown environments

• Non-magnetic (austenitic grades)

• Hygienic and easy to clean

• Resistant to chemicals and moisture

9. Limitations

• Lower tensile strength than carbon steel chains

• Higher cost

• Not ideal for extremely heavy shock loads (unless specially hardened)

10. Optional Variants

• Hollow pin SS roller chain

• Double pitch SS chain

• Attachment chains (A, K, SA types)

• Heavy-duty SS chain

• Side bow SS chain
