DIN 766 This standard applies for tested calibrated round steel link chains, grade 3, and defines their dimensions and mechanical properties. Material: steel, mimimum grade Ust 35-2. Design: bright, zinc-plated, hot-dip galvanized or stainless steel (AISI 301 or AISI 316). These chains are used in all fields of technology and for hand hoisting, but many not be used for motor-driven hoists and sling gear. Wire thickness: 4.0 – 23.0 mm. Load carrying capacity: 200-6.300 kg.
