CarTech® 15-15HS® Max Stainless

Generic Family: Steel - Wrought - Stainless - AusteniticSupplied by: Carpenter Technology Corporation
CarTech 15-15HS Max stainless is an austenitic, nitrogen-strengthened stainless steel. It can be considered for oil and gas industry applications such as nonmagnetic drill collars, stabilizers, and MWD housings, especially when high strength 140 ksi (966 MPa) minimum yield strength is desired.

The lower carbon content of CarTech 15-15HS Max stainless results in less tendency for carbides to precipitate in grain boundaries compared with normal chrome-manganese stainless grades. This provides CarTech 15-15HS Max stainless with improved resistance to intergranular stress-corrosion cracking. In addition, nickel, chromium, nitrogen, manganese and molybdenum are controlled to enhance the resistance to transgranular attack stress-corrosion cracking and pitting. Typical PRE equivalent is greater than 30.

A post-machining ID compressive stress treatment for drill collars has been developed to further improve the resistance to stress-corrosion cracking.

CarTech 15-15HS Max stainless is capable of high strength with improved pitting corrosion resistance when compared with competitive Cr-Mn-N stainless alloys.
