This chain has even better corrosion resistance than 400 class stainless chain. SAV collector chain is designed absorbing superiority of plastic chain, light weight and high corrosion resistance, as well as dramatic solution against weak point of plastic chain, initial elongation and abrasive wear by sand inclusion. In the aspect of recycle, SAV is also environment friendly chain. On the top of that, SAV chain can save tremendous cost and energy for installing, operation and maintenance due to light weight, and austenite stainless steel having outstanding corrosion resistance which assure longer life.
