A LONG LIFE STAINLESS STEEL CHAIN “MEGA CHAIN”
INTRODUCTION :
After a long research and development, we present "MEGA Chains", a whole new
concept, new revolution and design on roller chains. Specification of MEGA
Chains is design accordingly to International standard, can apply to all type of
sprockets. MEGA Chain design and concept are suitable for all type of material
for example, carbon steel, stainless steel and etc. At MING CHANG current stage
of planning and developing project, stainless steel had been placed on priority.
The reason for choosing the SUS 304 series material, it is an excellent
corrosion resistance and is the most popular series and is widely used in food,
chemical and etc. Current existing stainless steel chain (SUS 304) had a lot of
technical problem that so far not a single chain manufacture had overcome
problems of “Elongation, Wearing, Pin Push Out, Bush Push Out” on 304 Stainless
Steel Chains etc problem. Instead, they used different type of material such as
SUS600, SUS316 or SUS400, which are very high cost. But imagine by using the
same SUS304 material, MEGA Chain can deliver the result that current SUS 304
chain cannot deliver. MEGA Chains help to extend the life span of the machinery、reduce
the maintenance time and increase the production efficiency, and most important
is helping you to save cost.

STRUCTURE :
Structure of outer & inner plate which locked on to each other will increase the tensile strength. Due to the "lock on" between the outer plate and inner plate this will divided the shear stress especially on heavy load or tough environment
