CARTECH 347

CarTech 347 is a niobium+tantalum stabilized austenitic stainless steel. Like Type 321 austenitic stainless steel, it has superior intergranular corrosion resistance as compared to typical 18-8 austenitic stainless steels. Since niobium and tantalum have stronger affinity for carbon than chromium, carbides of those elements tend to precipitate randomly within the grains instead of forming continuous patterns at the grain boundaries. CarTech 347 should be considered for applications requiring intermittent heating between 425 and 900 °C (800 and 1650 °F). 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-1339. Producer or source: Carpenter Technology Corporation.

CARTECH 321

CarTech 321 is a titanium-stabilized chromium-nickel austenitic stainless steel that was developed to provide the performance of an 18-8 austenitic stainless steel with improved intergranular corrosion resistance. Since titanium has a stronger affinity for carbon than chromium, titanium carbide tends to precipitate randomly within the grains instead of forming continuous patterns at the grain boundaries. This datasheet provides information on composition, physical properties, hardness, elasticity, and tensile properties. It also includes information on corrosion resistance as well as forming, heat treating, machining, and joining. Filing Code: SS-1338. Producer or source: Carpenter Technology Corporation.

CARTECH 303

CarTech 303 is a free-machining austenitic stainless steel. The addition of sulfur to this 18-8 chromium-nickel austenitic stainless steel, which is ordinarily tough and difficult to machine, enhances the alloy’s machinability to the degree that it can be readily utilized for producing parts on automatic screw machines at about 70% of the speed of SAE 1212. This sulfur modification has led to widespread acceptance and use of this grade in the screw machine industry. This datasheet provides information on composition, physical properties, hardness, elasticity, and tensile properties. It also includes information on corrosion resistance as well as forming, heat treating, machining, and joining. Filing Code: SS-1337. Producer or source: Carpenter Technology Corporation.

CARTECH MP35N

CarTech MP35N is a wrought Co-Ni-Cr-Mo alloy that possesses a unique combination of ultra-high tensile strength (up to 2070 MPa, or 300 ksi), good ductility and toughness, and excellent corrosion resistance. The unique properties of CarTech MP35N are developed through work hardening, phase transformation, and aging. If the alloy is used in the fully work hardened condition, service temperatures up to 400 °C (750 °F) are suggested. 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: Co-134. Producer or source: Carpenter Technology Corporation.

CARTECH Ti-3Al-8V-6Cr-4Mo-4Zr (BETA C)

CarTech Ti-3Al-8V-6Cr-4Mo-4Zr, also known as Ti-3-8-6-4-4 and Beta C, is a metastable beta alloy used in the solution heat treated or solution heat treated and aged condition. It is appropriate for applications where very high strength, minimum weight, and corrosion resistance are important.
