ASTM A391 Tensile Steel Chain Test Equipment

0 0

ASTM A391 is specifically oriented to Grade 80 alloy steel chain for applications that include slings, lifting assemblies, and load binding. ASTM A391 requires alloy steel chain in this test to be made to a fully-killed fine austenitic grain process. To meet this standard the weld on the chain must be electrically welded or through a gas welding process. To meet the standards set by ASTM A391, the steel chain must meet the material property requirements for breaking force and elongation. ASTM A391 also requires the steel chain to be the correct dimensions for the appropriate size chain. ASTM A391 requires the chains to also be tested to at least proof load.
