Maple’s Services for Valve Our Valve Steel Forging parts have a worldwide reputation for their high quality and reliability. With our state-of-the-art testing laboratories and highly qualified workforce, we combine the highest standards of technology, quality and productivity. Accurate delivery time, fast service, we get the customer's praise. 4.Supporting Service for Valve parts As mentioned above, in order to work in adverse conditions, the performance of the Valve Valve Steel Forging parts must be excellent. Therefore, it’s not enough to only produce raw castings or forgings, but also need heat treatment, machining, surface treatment, NDT testing, etc. Heat treatment: heat treatment is the critical step to improve the mechanical properties of the workpiece. We can formulate the process according to the strength requirements of the parts, and improve the mechanical properties of the parts such as hardness, yield strength, tensile strength and elongation by heat treatment Machining: we have our own machine shop, and can complete almost all machining requirements with advanced equipment. Surface treatment: the purpose of surface treatment is to make parts work in adverse environment. Zinc plating can prevent parts from rusting; Nickel plating can enhance the wear resistance and corrosion resistance of parts; Phosphating can prevent parts from corrosion… Non-destructive testing (NDT): NDT is the last and most important step. Maple will NDT the parts to ensure that there are no surface defects (such as cracks, sand holes, blow holes) and no internal defects (shrinkage and slag) on the delivered parts.
