Specifications

• Driving chains
• Donghua driving chain is one of the most widely used and welcome products in the market. Its continuous innovative development is especially suitable to be the solutions for many conditions such as motorcycle chain、high strength roller chain、galvanized chain、nickel-plated chain、Dacromet-plated chain、lubrication-free chain and oilfield chain etc.
• Donghua supplies a large range of standard attachments and at the same time it can also develop suitable attachments for chains in order to meet various needs of customers.
• Conveyor Chain
• Rich design experience 、modern manufacture technology 、specially designed products for particular customers and the professional ability to face with various market competitions all make Donghua conveyor chain applied in many engineering fields such as escalator step-chain、double plus chain、palm oil chain、sugar mill chain、spreading machine chain、dry oven chain and bulk material conveyor chain etc.
• High quality material selection、powerful and precise heat-treatment ability and excellent assembly methods ensure Donghua conveyor chain meet strong and high efficiency needs of modern society.
• Donghua has products completely conforming to the international standard(ISO) and other advanced industrial standard(DIN、ANSI、BS )and in-plant standard products specially developed for customers.
• Stainless Steel Chain
• Stainless steel chain is especially suitable with anti-corrosion、clean or some chemicals strictly required conditions and high and low temperature conditions.
• Austenitic stainless steel chain series such as 304、306 and 312L material which has excellent anti-corrosion properties, applied in acidic、alkaline and -40°~600° temperature conditions. In comparison, 316L has better diamagnetism 、good suitability of severe temperature condition and anti-corrosion properties.
• Martensitic stainless steel chain series such as 2Cr13 etc. that has not only appropriate anti-corrosion properties but also the same strength with that of equal carbon content carbon steel.
• Agricultural Chain
• Donghua automotive chain can be classified into four kinds: silent chain、roller chain、bush chain and Hy-Vo chain according to its structure ,which widely used in engine、transmission gear and power driving system etc. At present, the main pitch range is 6.35-12.7mm. The chain is adopted high quality alloy steel material and special heat treatment technology, strictly conforming with ISO/TS 16949 quality system which offers acceptable products and service for main automotive manufacturers. “DONGHUA” brand automotive chain has advantages of high precision、high strength、high wear resistance and high fatigue performance.
