Carpenter Project 70+ Type 416 stainless steel is a modified version of Type 416 stainless steel with improved machinability when compared to conventional 416 (Alloy Digest SS-459, March 1985, and Alloy Digest SS-769, November 1999). The alloy is a hardenable ferritic chromium steel. This datasheet provides information on composition, physical properties, hardness, and tensile properties as well as fracture toughness. It also includes information on corrosion resistance as well as forming, heat treating, machining, and joining. Filing Code: SS-882. Producer or source: Carpenter Technology Corporation.

CARPENTER PROJECT 70 STAINLESS TYPE 416 is an improved modification of Carpenter Stainless No. 5, the first free-machining stainless steel ever made. This grade has significantly better machinability than the conventional AISI Type 416. Carpenter Project 70 Stainless Type 416 is suited particularly for automatic screw-machine operations where the longer tool life results in more productive machine time. Among its many uses are fittings, gears, shafts and valve stems. This datasheet provides information on composition, physical properties, hardness, elasticity, and tensile properties as well as fracture toughness. It also includes information on high temperature performance and corrosion resistance as well as forming, heat treating, machining, and joining. Filing Code: SS-459. Producer or source: Carpenter.

Project 7000 Stainless Type 416 is a version of Carpenter Stainless Type 416 and is an improved-machining version of Project 70 Stainless Type 416 (see Alloy Digest SS-459, March 1985). Project 7000 Stainless Type 416 offers benefits in long production runs and is available as bar stock in the annealed, intermediate, and hard temper conditions. This datasheet provides information on composition, physical properties, hardness, and tensile properties as well as fracture toughness. It also includes information on corrosion resistance as well as forming, heat treating, machining, and joining. Filing Code: SS-769. Producer or source: Carpenter.

PROJECT 70 182-FM is a ferritic free-machining stainless steel designed to have machinability approaching that of AISI Type 416 stainless steel with corrosion resistance comparable to AISI Type 303 stainless steel. It is ideally suited for automatic screw machines and can be used for many of the same applications as Type 303. 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, joining, and surface treatment. Filing Code: SS-334. Producer or source: Carpenter.

PROJECT 70 is a modified Type 416 corrosion resistant steel offering improved machinability. It is recommended for automatic screw machine operations where longer tool life results in more productive machine time. This datasheet provides information on composition, physical properties, hardness, elasticity, and tensile properties as well as fracture toughness. It also includes information on corrosion resistance as well as forming, heat treating, machining, joining, and surface treatment. Filing Code: SS-170. Producer or source: Carpenter.

CARPENTER STAINLESS No. 5-F is a modification of AISI Type 416 stainless steel and was designed for an optimum combination of machinability and corrosion resistance. It comprises a specially balanced analysis and is essentially non-hardenable. It is recommended for all screw-machine applications, particularly those involving intricate machining operations or where superior finishes are required as-machined. Its uses include valve trim, carburetor needles and many other screw-machine parts. This datasheet provides information on composition, physical properties, hardness, and tensile properties as well as creep. It also includes information on high temperature performance and corrosion resistance as well as forming, heat treating, machining, joining, and surface treatment. Filing Code: SS-275.
