Ductile iron is also significantly less likely to corrode than cast iron. This is a stainless steel trim, 150 LB globe valve. Stainless steel is a shiny, silver-colored metal that is minimally porous and very durable. It has a thin, transparent layer that protects and even heals the metal on it’s outer sides when scratched or damaged.

Why ductile iron couplings on stainless steel

Jan 15, 2020  The use of Victaulic couplings with ductile iron housings on stainless steel pipe is common practice when pipe material selection is based on compatibility with the fluid media and where the risk of external corrosion is low. Due to the design of the coupling housings and elastomer gasket, the housings will never contact the internal fluid media.

Ductile iron - Wikipedia

Ductile iron, also known as ductile cast iron, nodular cast iron, spheroidal graphite iron, spheroidal graphite cast iron and SG iron, is a type of graphite-rich cast iron discovered in 1943 by Keith Millis. While most varieties of cast iron are weak in tension and brittle, ductile iron has much more impact and fatigue resistance, due to its nodular graphite inclusions.
