Carbon, Silicon, Manganese, Phosphorus, Sulfur are called "Five Elements". They are the main impurities in steel. Carbon improves steel hardness. Silicon strengthens the steel strength. Manganese contributes to increase the steel firmness, strength and wear resistance. Phosphorus reduces the steel plasticity and toughness and appearing cold brittleness. Meanwhile, It can significantly increase the strength of steel, and improve the atmospheric corrosion stability. Sulfur makes the hot brittleness of steel high.

CD4MCu is a duplex stainless steel, with greater corrosive resistance than standard stainless steel. CD4MCu provides significantly better chloride stress cracking resistance than standard stainless steel, and much better localized corrosion resistance.
CD4MCu allows the pumps to be used in more abrasive applications, and it won't pit like regular stainless steel, has a better stress/corrosive cracking resistance than standard stainless, and higher strength than standard stainless steel. And compared with regular cast iron material, it is much more resistant to corrosion and much stronger.
Most of our dealers have access to 11 of Cornell's most popular models in CD4MCu, allowing us to slash production time and price. Cornell can supply a CD4MCu pump in as little as one to two weeks.
