The H-Lift Stainless Steel JIS Standard Chain is a welded round link chain manufactured specifically to Japanese Industrial Standards (JIS), designed for excellent performance in marine and outdoor environments.
Constructed from high-quality 316 marine-grade stainless steel, providing exceptional resistance to corrosion and harsh seawater conditions.
Features an electropolished surface for a superior, smooth finish that enhances both durability and aesthetic appeal.
Available in wire diameters ranging from 2mm to 12mm to accommodate various light-duty securing, lashing, and general utility requirements.
Strictly designed for static applications and general outdoor use; it is not approved or certified for industrial overhead lifting.
The Stainless Steel JIS Standard Chain is a premium commercial-grade round link chain manufactured to conform precisely to Japanese Industrial Standards (JIS). Featuring a highly reflective electropolished surface, it maximizes innate corrosion resistance and offers an attractive aesthetic, making it widely used for anchor chains, vessel mooring lines, chemical processing plants, and decorative architectural installations.
⚠️ SAFETY WARNING: NOT FOR OVERHEAD LIFTING. This chain is designed for holding, securing, and conveying. It is an uncalibrated commercial chain and is NOT suitable for industrial lifting purposes or overhead suspension.
✅ Standard Compliance
Manufactured to conform precisely to Japanese Industrial Standards (JIS) for round link chains, ensuring seamless compatibility with JIS-rated equipment, hardware, and Asian markets.
🛡️ Premium Material Grades
SUS304: Excellent for general industrial, architectural, and outdoor applications. SUS316: Offers superior resistance to rust and pitting, making it the required choice for marine and chemical environments.
✨ Electropolished Finish
Features a superior electropolished surface. This advanced treatment removes microscopic surface imperfections, providing a high-shine aesthetic while maximizing the chain's corrosion resistance.
🛠️ Versatile Applications
Widely used as an extremely durable, rust-proof solution for boat anchor chains, mooring lines, food processing equipment, and heavy-duty architectural boundaries.
Q: What is the difference between SUS304 and AISI 304?A: There is no functional difference. SUS304 is the Japanese Industrial Standard (JIS) designation, while AISI 304 is the American standard designation for the exact same grade of stainless steel.
Q: Can I use this JIS chain for an overhead hoist?A: No. While SUS316 stainless steel is incredibly strong and corrosion-resistant, these standard JIS chains are not proof-tested or calibrated for overhead lifting. For lifting, you must use a rated and tagged alloy lifting chain.
Chain Grade Guide
What is the Difference Between Welded Chain Grades?
🚫 Carbon Steel ChainGrades 30, 43, 70 Used for tie-downs, towing, and securement. NEVER used for overhead lifting.
✅ Alloy Steel ChainGrades 80, 100 Specifically designed and heat-treated for Overhead Lifting and Sling Assemblies.
How is "Grade" Calculated?
The grade number represents the chain's tensile strength (mean stress value). It is calculated by dividing the tensile force (Newtons) by the cross-sectional area of the two links ($mm^2$).
As the Grade Increases:
The material becomes harder and more resistant to abrasion.
The Strength-to-Weight ratio increases (more lifting power, less weight).
The Working Load Limit (WLL) increases significantly.
Towing, general utility, load securement. Stronger than G30.
NO
Grade 70 (Transport)
Heat-Treated Carbon
Heavy Duty Securement. Standard for trucking tie-downs. Identified by Gold/Yellow finish.
NO
Grade 80 (Alloy)
Alloy Steel
Standard Lifting Slings. High ductility (stretch) to absorb shock.
YES
Grade 100 (Premium)
Alloy Steel
Heavy Lifting. 25% stronger than G80. Harder surface for abrasion resistance.
YES
Common Problems & Critical Safety Warnings
Even with the correct grade, misuse can lead to catastrophic failure. Ensure your riggers are trained to avoid these three common hazards:
⚠️ 1. The Hoist Chain Trap
A frequent and dangerous mistake is using the load chain inside a hoist to wrap around a load.
The Design: Hoist load chain is hardened specifically to fit internal sprockets (tight tolerances). It lacks the ductility (stretch) required for a sling.
The Risk: Wrapping it around a load deforms the links. When retracted, the deformed links can snap or destroy the internal hoist mechanism.
⚠️ 2. The "Gold Chain" Error
Using Grade 70 (Gold) chain for overhead lifting is a common error because the chain looks robust.
Why it Fails: Grade 70 is heat-treated for abrasion resistance (for rubbing against truck beds), not for the elongation needed to absorb the dynamic shock of a crane lift. It may snap suddenly without warning.
⚠️ 3. General Neglect
Alloy chain is tough, but not invincible. Proper storage and inspection are vital.
Corrosion: Leaving chain on damp shop floors promotes pitting and stress corrosion cracking.
Inspection: Chains must be inspected regularly for nicks, gouges, and elongation (stretching).
