Description
– G80 standard stainless steel long link chain, also known as fishing or lashing chain, is a high-strength, heat-treated alloy steel chain designed for overhead lifting and other demanding applications.
– It is characterized by its long links, typically with a pitch of 6 times the diameter (6d), and is manufactured to meet specific standards for breaking strength and working load limits.
Key Features:
Material:
Made from high-quality alloy steel, often manganese steel, and heat-treated to achieve its high strength and durability.
Link Design:
Features long links with a pitch of 6 times the chain’s diameter (6d).
Grade 80:
Meets the Grade 80 standard, indicating a high strength level suitable for heavy-duty applications.
Welded Construction:
Typically flash butt welded, resulting in a smoother weld and stronger joint compared to other methods.
Heat Treatment:
Undergoes heat treatment to enhance its strength and meet specified breaking strength requirements.
Proof Load Testing:
100% of chains are proof load tested with 2.5 times the working load limit (WLL).
Surface Finish:
Can be painted (e.g., yellow, blue, black), galvanized (electrical or hot-dip), or provided with other finishes for corrosion resistance.
Marking:
Typically embossed with a Grade Mark and/or Batch Mark for traceability.
Applications:
Used in various applications, including overhead lifting, fishing, lashing, mooring, towing, and dredging.
Safety Factor:
Often designed with a safety factor of 4:1, meaning the breaking strength is four times the working load limit.
Standards:
May be manufactured to meet standards like EN818-2, which specifies requirements for short link chain.
