Precision ferrite machining|exhaust manifold system for automotive industry

WKM specializes in braking, chassis, steering and exhaust manifold system for automotive industry.We introduce unique process control skills to produce assorted cast iron materials with critical specification. For example, we are now very familiar with high-temperature resistant ductile iron (Hi Si-Mo) for diesel engine of heavy-duty trucks and the ductile iron we produce meets the specification of SAE J2582 Grade 2. In additional to the Hi Si-Mo, WKM also be able to produce Austempered Ductile Iron (ADI), which significantly improves both the strength and wear resistance of ductile iron. ADI is a proven cost-effective alternative to cast and forged steel and offers lots of advantages. Cast stainless steels and silicon-molybdenum ductile irons offer the best potential to meet manifold's general requirements, e.g. corrosion resistance, low thermal conductivity, low thermal expansion coefficient, high temperature fatigue strength, high temperature creep resistance, antioxidation properties and high temperature yield strength. Our materials expertise and capability to produce a multitude of materials, ranging from Ductile Iron to Ferritic and Austenic cast iron, is a significant strength to our customers.
