DIN 764 Stainless Steel Middle Chain: Ideal for Strength and Corrosion Resistance
DIN 764 Stainless Steel Middle Chain is a welded chain carefully manufactured according to German Industrial Standard DIN 764. Compared with long link designs, its medium-length links (also often called short links) make it superior in strength and load-bearing capacity, while giving full play to the inherent advantages of stainless steel.
Compliant with DIN 764 standards
Produced in strict accordance with German Industrial Standard DIN 764, ensuring dimensional accuracy and welding quality meet internationally recognized specifications.
High-quality stainless steel material
Available in AISI 304 for general corrosion resistance and AISI 316/316L for enhanced resistance to chloride environments.
High strength and load-bearing capacity
Shorter chain links disperse stress more evenly when stretched, providing higher tensile strength for demanding applications.
Excellent corrosion resistance
The passivation protective film effectively resists rust, acid, alkali, and salt, significantly extending product life.
Strong and durable
Precise welding processes ensure the chain structure is strong and resistant to deformation or breaking under harsh conditions.
Wide range of applications
Ideal for areas with dual requirements for mechanical strength and environmental corrosion resistance.
The excellent performance of DIN 764 stainless steel center chain makes it widely used in the following fields:
-
● Ship and marine engineering: Mooring chains, auxiliary anchor chains, and dock equipment connection.
-
● Industrial equipment: Conveyor belts, chain conveyors, and industrial guardrails.
-
● Agricultural machinery: Reliable connection and fixing for fencing and livestock management.
-
● Building and structure: Isolation chains and decorative purposes requiring aesthetic corrosion resistance.
-
● General uses: Pet chains, gardening tools, and access control safety chains.

Frequently Asked Questions (FAQ)
What is the main difference between DIN 764 and long link chains?
DIN 764 chains feature middle-length links, which provide a better balance of weight and strength compared to long link chains, allowing for higher load-bearing capacity and better stress distribution.
When should I choose AISI 316 stainless steel over 304?
AISI 316 contains molybdenum, making it superior for marine environments or chemical processing where resistance to chloride-induced pitting and crevice corrosion is essential. 304 is suitable for freshwater and standard outdoor use.
Is the DIN 764 middle link chain suitable for overhead lifting?
No, DIN 764 chains are generally not recommended for overhead lifting or high-risk safety applications. For those purposes, you should use specialized, certified lifting chains like Grade 80 or Grade 100.
How does the "passivation film" protect the chain?
Stainless steel naturally forms a thin, invisible passivation layer of chromium oxide. This layer acts as a barrier against moisture and oxygen, preventing the underlying metal from rusting.
Can these chains be used in agricultural machinery?
Yes, they are excellent for agricultural use because they provide a reliable, strong connection that can withstand the moisture and corrosive elements common in farming and livestock management.
What determines the load-bearing capacity of these chains?
The capacity is determined by the material grade (304 vs 316), the diameter of the link (ranging from 4mm to 26mm in our specifications), and the precision of the welding process used during manufacturing.
