CD4MCu is an Fe-Cr-Ni-Cu-Mo alloy with a duplex structure of ferrite and austenite. Moderately high strength and hardness are combined with good ductility and impact properties, resulting in an alloy with superior resistance to abrasion or erosion-corrosion.
CD4MCu provides significantly better stress/corrosive cracking resistance, and less pitting than standard stainless steel. It has a higher strength and thus is more durable.
CD4MCu combines outstanding corrosion resistance with nearly twice the strength of many stainless types. It can be age-hardened to increase its Brinell Hardness Number (BHN). This alloy has proven useful in sulphuric acid environments and seawater applications. It resists abrasive wear and galling, can be readily machined, and is weldable without preheating. This duplex alloy is also known as MTEK 29M.
