Grade 100 (G100) lifting chains
Category
Lifting and lashing, chain, short link chain, round link chain lifting, Grade 100 chain,G100 chain, chain sling, sling chains, ASTM A973 / A973M-21 standard specification for Grade 100 alloy steel chain
Application
Lifting and lashing, loads lifting, loads binding
SCIC Grade 100 (G100) chains for lifting are made as per ASTM A973 / A973M-21 standards, with nickel chromium molybdenum manganese alloy steel per DIN 17115 standards; well designed / monitored welding & heat-treatment ensure chains mechanical properties including test force, breaking force, elongation & hardness.
