ASTM Grade 80 Chain close left right

ASTM Grade 80 Chain

ASTM Grade 80 ChainGrade 80 chain is typically finished with a black armour? coating. This is a tough durable painted finish. Other finishes available are Electro Galvanized, Powder Coated, Hot Dipped Galvanized and Silver Shield.
Introduction

Features and Benefits

  • Produced from a high quality alloy steel
  • Special induction heat treatment process that maximize strength and increase the elongation characteristics.
  • Finish is black armour coat
  • Meets or exceeds all NACM & ASTM standards
  • Approved for over head lifting
Parameter

Grade of Chain: NACM (National Association of Chain Manufacturers & ASTM (American Society for Test Materials) classify chains in various grades. The higher the grade, the higher the working load limit for the same size of chain.

Working Load Limit (WLL): (rated capacity) Is the maximum working load that should be applied In direct tension to an undamaged straight length of chain.

Proof Test: (manufacturing test force) Is a term designating the minimum tensile force which has been applied to a chain under a constantly increasing force In direct tension during the manufacturing process. These loads are manufacturing integrity tests and shall not be used as criteria for service or design purpose.

Minimum Breaking Force: The minimum force at which the chain during manufacture has been found by testing to break when a constantly increasing force is applied in direct tension. Breaking force values are not guarantees that all chain segments will endure these loads. This test is a manufacturer’s attribute acceptance test and SHALL NOT be used as criteria for service and design purpose.

Overhead Lifting: The process of lifting that would elevate a freely suspended load to such a position that dropping a load would present a possibility of bodily injury or Property damage.
