1. Basic Overview

DIN763 chain is a long-link welded chain, usually made of alloy steel or carbon steel, and heat-treated to improve strength and wear resistance. Its chain links are welded on the side to enhance structural stability, suitable for a variety of load scenarios, but it should be noted that it cannot be used for overhead lifting or “basket-style” lifting.

– Standard type: divided into long links (DIN763) and short links (DIN766). Some suppliers also provide stainless steel materials (such as 304/316) to meet anti-corrosion requirements.

– Surface treatment: common galvanizing (bright, hot dip), painting, blackening, Dacromet coating, etc., can be selected according to the use environment.

2. Materials and Processes

1. Materials

– Alloy steel: After heat treatment, high-tensile alloy steel can reach a breaking load of 40,789 kg, which is suitable for heavy-load scenarios.

– Stainless steel: 304/316 stainless steel chains are corrosion-resistant and are often used in marine or humid environments.

– Carbon steel: Carbon steel materials such as Q235 are low-cost and suitable for general industrial use.

2. Manufacturing process

– Automatic flash welding technology is used to ensure the strength of chain link connection.

– The safety factor is 4:1, and the verification load is 2.5 times the working load, which meets international standards (ISO, BS, JIS, etc.).

3. Main application areas

1. Shipbuilding and marine engineering

– As an anchor chain or lashing chain, it is used for ship anchoring and cargo fixing.

2. Lifting and industrial equipment

– It is matched with hoists, hooks, etc. to form a lifting chain system, which is suitable for scenes such as factories and mines.

3. Safety protection and decoration

– Guardrail chains, decorative chains (such as building fences, lighting).

4. Agriculture and transportation

– Trailer lashing, logging operations, farm equipment connection, etc.
