Iron nitride-
hardened steel

NitroSteel bars and tubes hardened by the Nitrotec process outperform hard chrome plated products because of their ability to resist corrosion and wear, and retain lubrication. The process diffuses iron nitride into the steel, rather than depositing plating onto the steel's surface. So unlike chrome, which flakes, slivers and blisters as it fails, NitroSteel's wear layer is part of the steel, avoiding the flaking and blistering. The Nitrotec process, as an atmospheric treatment instead of electrodeposition, presents a dimensional uniformity. NitroSteel bars have found service on agriculture, material handling, construction and military equipment. A.M. Castle & Co, 3400 North Wolf Rd, Franklin, IL 60131. 847-455-7111. Circle 405.

Copper-based specialties. Updated information is offered on a data sheet regarding this company's copper-based master alloys, hardeners and deoxiders. These include 2% boron copper, 2% lithium copper and 33% zirconium copper. Typical shapes, depending on the selected product, can be chosen as ingots, waffles, cubes, slabs, shot and pieces. These metallurgical specialties provide cost-effective deoxidation and modification of mechanical properties. Belmont Metals Inc, 330 Belmont Ave, Brooklyn, NY 11207-4000. 718-342-4900. Circle 408.

Titanium powders. Ultraclean, spherical and free-flowing titanium and titanium alloy powders are offered with precise particle size distributions. The powders are offered in commercially pure Ti₆Al-4V, Ti₆Al-2 Sn-4 Zr-2 Mo, and other compositions. They feature a controllable median particle size distribution within a 18 to 325 Mesh range, and can be plasma sprayed, sintered, or consolidated by hot isostatic pressing or extrusion. Starmet Corp, 2229 Main St, Concord, MA 01742. 978-369-5410. Circle 409.

Powdered metal gerotor manufacturer. Aided by proprietary computer software, this company offers comprehensive product engineering, development and manufacturing to produce powder metal gerotors and associated porting for automotive and other applications. Their software provides consistent lobe profiles with very small tip clearances, which translates into higher efficiency, lower noise and higher pressure capabilities for the pumps. Federal Mogul, PO Box 1966, Detroit, MI 46239. 248-354-7700. Circle 412.

High strength-to-weight ratio alloy. AerMet 310 alloy combines an unprecedented high strength-to-weight ratio with a fracture toughness and ductility that are exceptional at the material's high strength level. It is offered for applications such as aircraft landing gear and hardware, tooling, and any parts or components that might benefit from higher strength, smaller size and/or lighter weight. AerMet 310 can achieve an ultimate tensile strength of 315 ksi, with a 1.10 mega-inch strength-to-weight ratio. Charpy V-notch impact tests showed AerMet 310 had an average impact energy in excess of 20 ft. lbs., indicating high damage-tolerance. Carpenter Specialty Alloys, PO Box 14662, Reading, PA 19612-4662. 610-208-2235. Circle 413.

Composite metal products. Custom-engineered metal products are offered that combine two material properties, such as electrical conductivity and corrosion-resistance, or high mechanical strength and biocompatibility. Two or more layers of gold, silver, platinum, palladium, niobium, titanium and other alloys can be bonded to copper- and nickel-based alloys. The resulting product is supplied in wire, rod or bar stock, in sizes from 0.002 to 1.5 in. OD. Anomet Products Inc, 830 Boston Turnpike, Shrewsbury, MA 01545. 508-842-3069. Circle 410.

Precipitation-hardening stainless steel. Corrax stainless mold steel offers easy heat treatment, excellent stability and very high corrosion resistance. It is supplied in the solution-treated condition at 34-36 Rockwell C, and this hardness can be increased by a low-temperature aging treatment to a maximum of 50 Rockwell C. This lends to the manufacture of large, complex molds for medical, plastic and rubber parts, where hardening and tempering of a conventional steel grade could incur excessive distortion or even gross cracking. The grade has highly uniform physical and mechanical properties, even in large dimensions. Uddeholm, 4902 Tollview Dr, Rolling Meadows, IL 60008. 800-833-4656.

Chrome-plated shafting. Used by manufacturers of piston rods, pins, guide posts and similar components, CHROMEROD 100 offers a 100,000 psi minimum yield strength, excellent machining characteristics and superior surface finish. Standard plating is 0.0005 in./side minimum, and heavier thicknesses are available. CHROMEROD 100 is available in 1/2 to 4 1/2 in. round, with diameters up to 10 in. offered in alloy 4140. Enduro Ind, 2001 Orchard Ave, Hannibal, MO 63401. 573-248-2084. Circle 414.

Powder metallurgy sprockets. The Duplex process enables appropriate sprockets or gears to be manufactured with reduced weight, rotational inertia and increased sound dampening properties, while reducing overall cost. The essential feature of this approach is the selective application of a high hardness, high strength material for the teeth, and a lower duty material with adequate keyway strength for the core. Zenith Sintered Products Inc, North 112 West 18700 Mequon Rd, Germantown, WI 53022. 414-255-9050. Circle 406.
