Superelso 690CR, also known as SE 690CR, is a high yield strength, quenched-and-tempered alloy for jack-up legs of offshore drilling platforms. This datasheet provides information on composition and tensile properties as well as fracture toughness. It also includes information on corrosion resistance as well as forming, heat treating, and joining. Filing Code: SA-577. Producer or source: Industeel USA, LLC.

Lukens 690Z is a quenched and tempered steel of high strength but with low-carbon to obtain good toughness. The alloy meets mobile offshore drilling platform requirements. This datasheet provides information on composition, physical properties, and tensile properties as well as fracture toughness. It also includes information on joining. Filing Code: SA-527. Producer or source: International Steel Group Inc.

Carlson alloy 926 Mo is a superaustenitic 6% Mo stainless steel that resists highly corrosive environments and has excellent chloride pitting, crevice, and stress-corrosion cracking resistance. It can be utilized where the performance of conventional austenitic stainless steels is bor-derline, or as a cost-effective substitute for nickel alloys. The higher mechanical properties that allow designs with thinner sections than con-ventional stainless steels are highly desired for oil platforms. This datasheet provides information on composition, physical properties, hardness, elasticity, and tensile properties. It also includes information on corrosion resistance as well as forming, machining, and joining. Filing Code: SS-842. Producer or source: G.O. Carlson Inc., Electralloy.
