R&D results

Huangshan Zhongyou Chain has been providing and supporting wear-resistant, alkali-resistant, cleaner, more environmentally friendly, more wear-resistant and reliable stainless steel chains for the past 18 years and beyond for food, beverage, pharmaceutical, and packaging host conveyor systems and maintenance worldwide. We can also provide you with faster, more efficient, more energy-saving and environmentally friendly power and transmission solutions. The dimensions of all Huangshan Zhongyou stainless steel chains conform to ISO, ANSI, DIN, BS and JIS standards. All parts of Huangshan Zhongyou stainless steel chain are made of AISI304/1.4301, and AISI630/1.4542 (17-4PH), a special stainless steel material, is also used to meet the requirements of higher wear resistance, corrosion resistance and higher strength in special environments. The spectrometer and advanced salt spray testing machine imported from Germany ensure that the chemical composition of each batch of raw materials put into production is 100% up to standard. We have strict hardness requirements for the raw materials of each part to ensure better wear resistance and strength of each part. All Huangshan Zhongyou stainless steel chains are pre-stretched by 30% breaking load.
