Al Tech 416 EZ is one variation of AISI Type 416, the free-machining martensitic stainless steel that has been one of the staples of the automatic machining industry. It offers higher hardenability than other AL Tech variations, but does not machine as readily as them. 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, and joining. Filing Code: SS-665. Producer or source: AL Tech Specialty Steel Corporation.

AL Tech 416 EZR is one variation of AISI Type 416, the free-machining martensitic stainless steel that has been one of the staples of the automatic machining industry. It offers higher machinability than Type 416 EZ (Alloy Digest SS-665, December 1996), but is not recommended for bright hardening. 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-667. Producer or source: AL Tech Specialty Steel Corporation.

Allegheny Ludlum Type 416 stainless steel is a free-machining martensitic stainless steel, which can be hardened by heat treatment to higher strengths. It has better machining properties than the austenitic grades but lower corrosion resistance. This datasheet provides information on composition, physical properties, and tensile properties. It also includes information on corrosion resistance as well as heat treating, machining, and joining. Filing Code: SS-796. Producer or source: Allegheny Ludlum Corporation.

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 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. Producer or source: Carpenter. Originally published July 1972, revised July 1980.

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.

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.

AL Tech 416EZ and 430F are magnetic, free-machining stainless steels specifically designed for use in high-speed, automatic machining operations. These modifications retain, in so far as possible, the good mechanical properties and corrosion resistance of the basic compositions which they represent. Sulfur is added to produce the free-machining characteristics. AL Tech 416EZ is a martensitic stainless steel and 430F is ferritic. Data are typical; do not use for specification or final design. 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 high temperature performance as well as forming, heat treating, and machining. Filing Code: SS-359. Producer or source: AL Tech Specialty Steel Corporation.
