Welcome to HANDUN chain
Professional Engineer Class Chain Manufacturer
There are two main series of standard precision roller chain: American Standard and Europe Standard. Most of other state standard are coming from these two standard.
A Seires precision roller chain complies to international standard:
| American Standard: | ANSI B 29.1 |
| Germany Standard: | DIN 8188, DIN8187 |
| International Standard: | ISO R606 |
| Japanese Standard: | JIS B 1801 |
Chain Size:
ISO Standard: 04C, 06C, 08A, 10A, 12A, 16A, 20A, 24A, 28A, 32A, 36A, 40A, 48A
ANSI Standard: 15, 25, 35, 41, 40, 50, 60, 80, 100, 120.140, 160, 180, 200, 240
GOST Standard: NP-19,05-31,8, NP-25,4-60, NP-31,75-89, NP-38,1-127, NP-44,45-172,4, NP-50,8-227, NP-63,5-354
DIN Standard: 04B,05B,06B,08B,10B,12B,16B,20B,24B,28B,32B,40B,48B,56B,64B,72B

Material:
1. high quality Alloy steel.
2. Stainless Steel. We have 3 kinds of stainless steel for your choice. Usually, we use 304SS.
304 SS Series: offer excellent resistance to corrosion and extreme temperatures. The 304 SS Series is ideal for environments that require tougher resistance to acids and alkali.
316 NS Series: The 316 NS Series provides maximum corrosion resistance and temperature resistance, with virtually no magnetic permeability. These are critical factors in many applications involving electronics or the production of steel.
600 AS Series: AS Series chain was developed for the most demanding applications. With precipitation-hardened round parts, the 600 AS Series combines high load capacity and high corrosion resistance.
Suface Treatment:
The carton steel roller chain can be nickel plated, zinc plated, Daromet-plated for enirnoments require resistance to acids and alkali.
1. More than 45 years experiences in Engineer Class Chain.
2. Cooperated with many famous brand in the world.
3. Imported machinery to assure high quality.
4. Also Produced special sprocket and coupling
Specialised in:
1. Automobile industry
2. Steel & Metallurgical industry
3. Cement industry
4. Agricultural industry
5. Lumber industry
6. Palm oil industry
7. Sugar industry
8. Rubber industry
9. Heavy machinery industry.
Q: Why the prices are very different for same size chain in China chain factories.
A: There are lots of ways to less the cost in chain production.
-The prices from some steel factory are cheaper but the physical properties are poor.
-Reduce production process: Plate material annealing, twice punching plate hole, centerless grinding, shot peening, chain pre-strength, etc.
-Use cheaper material for pin, bush and roller.
-Use thinner chain plates.
-Shorter the heat-treatment time or overload in furnace each time.
Q: Why we never use 45 (1045) to produce conveyor chain plate.
A: In Europe, it is common to use 1045 steel as conveyor chain plate to less the cost. However, the steel 1045 made in China cannot reach to our requirements. The main problem is big deformation after heat-treatment. It will be difficult to control the pitch accuracy.
Q: Why we use 40Mn as plate material.
A: 40Mn has higher C element and Mn cement. Mn can Increase hardening depth of steel, lower quenching temperature, refinine the pearlite structure to improve its mechanical properties. Mn content in 40Mn steel is 0.7~1.0. It is ideal ingredients and can get good strength and fatigue life. When Mn content increase, metal crystal particles gradually decrease and reach a certain value after it reach to 0.5 and the tensile and hardness also reach to a certain value. After it is higher than 1, the fatigue life of steel decreased.
Q: Why the prices may very different for similar size conveyor chain.
A: We offer the prices according to the material and chain producing process. We design the conveyor chain basis on application environment. Different environment (normal, high wear resistance, heady-duty, slightly corrosive, corrosive, etc.) will use different material with different producing process. If the chain used in corrosive environment also heady-duty, we need to use best material. The plate holes, bush, pin and roller may will be produced by CNC material and heat-treatment by multi-purpose furnace. The price will be very high.
Q: Why we can say we are China engineer chain specialist.
A: We have more than 45 years experiences in engineer chain, serving lots of industry giants in China. During analysis lots of imported conveyor chain, we are familiar with the chain design and producing process from the world first class chain factories.
