DIN Standard Welded Link Chain

DIN Standard Welded Link Chain refers to welded round steel link chains manufactured in strict accordance with German Industrial Standards (DIN), widely used across general industrial, agricultural, marine, transport, and lifting applications.

Basic Overview

Core Standards: Primarily governed by DIN 5685 (general-purpose), DIN 763/764/766 (short/medium/long link), and DIN 685 (tested lifting chains).
Link Types: Standardized into Short Link (DIN 5685-A / DIN 763), Medium Link (DIN 764), and Long Link (DIN 5685-C / DIN 766).
Materials: Low-carbon steel, medium-carbon steel, high-carbon steel, alloy steel, and stainless steel (AISI 304/316).
Surface Treatments: Self-color, electro-galvanized, hot-dip galvanized, black oxide.
Size Range: Typically 2 mm – 24 mm in link diameter.
Testing: Proof-tested to ensure compliance with specified mechanical properties.
