There has long been a debate on whether Carpenter 20 is a stainless steel or a nickel alloy for the reason that the nickel content is right on the border of defining it as one way or the other. Either way it is still excellent for corrosion resistance. As a manufacturer, supplier, stockiest and exporter, we offer these UNS N08020 Valves in custom-made sizes and thicknesses as per the exact demands of our esteemed clients.
