Carpenter SCF 19 Max alloy is an austenitic, nitrogen-strengthened stainless steel of high manganese content. The alloy is used for downhole equipment and where pitting is present. See Alloy Digest SS-748, June 1999, for the original alloy. This datasheet provides information on composition, physical properties, elasticity, and tensile properties. It also includes information on corrosion resistance as well as forming, heat treating, machining, and joining. Filing Code: SS-1193. Producer or source: Carpenter Specialty Alloys.

15-15HS MAX stainless is an austenitic alloy strengthened by both nitrogen and high manganese. It has a low permeability and can be considered for nonmagnetic drill collars. This datasheet provides information on composition, physical properties, hardness, and tensile properties. It also includes information on corrosion resistance as well as forming, heat treating, machining, and joining. Filing Code: SS-988. Producer or source: Carpenter Specialty Alloys.

15-15LC MODIFIED STAINLESS is an austenitic alloy with high manganese and nitrogen, with low permeability, and good corrosion resistance. The alloy should be considered in down-hole applications such as drill collars. This datasheet provides information on composition, physical properties, hardness, elasticity, and tensile properties as well as fracture toughness and fatigue. It also includes information on heat treating, machining, and joining. Filing Code: SS-588. Producer or source: Carpenter.
