CHROMEL-D is a special 35-20 nickel-chromium alloy developed primarily for use as heating elements in industrial furnaces designed to operate in the critical temperature range between 1500 and 1800 F. with controlled atmospheres. 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 joining. Filing Code: SS-98. Producer or source: Hoskins Manufacturing Company.

Colmonoy No. 635, a Nickel-base hard surfacing Alloy, contains a formulated mixture of both crushed and atomized powders. It achieves a hardness of RC 58-63 with tungsten carbide particles. Typical applications include hardfacing of pump components and shaft sleeves. It is supplied as a powder for aplication with Wall Colmonoy’s SPRAYWELD Process. This datasheet provides information on composition, physical properties, microstructure, and hardness. It also includes information on heat treating, machining, and powder metal forms. Filing Code: Ni-495. Producer or source: Wall Colmonoy Corporation.

Colmonoy 730 is a tough Ni-Cr-W matrix alloy that holds extremely hard tungsten-carbide particles with a finer mesh tungsten carbide than Colmonoy 750 (Alloy Digest Ni-546, October 1998). The alloy is used on pump plungers and sleeves for protection from fine-particulate abrasive conditions. Colmonoy 730 minimizes packing wear. The alloy is finished by grinding. This datasheet provides information on composition, physical properties, microstructure, and hardness. It also includes information on machining, joining, and powder metal forms. Filing Code: Ni-547. Producer or source: Wall Colmonoy Corporation.

COLMONOY No. 70 and No. 72 contain high tungsten which hardens the matrix and provides superior hard-facing materials. No. 70 hasexcellent resistance to fretting corrosion. No. 72 is harder than No. 70 and provides better resistance to low-stress abrasion and is well suited to resist scouring actions. This datasheet provides information on composition, physical properties, hardness, and elasticity. It also includes information on high temperature performance as well as forming, heat treating, machining, joining, and powder metal forms. Filing Code: Ni-210. Producer or source: Wall Colmonoy Corporation.

WALLEX No. 40 is a self-fluxing, cobalt-base hard-surfacing alloy with excellent resistance to a combination of corrosion and abrasion and relatively good impact properties. It has excellent red hardness and weldability. It is supplied only as atomized powder for application with Wall Colmonoy's SPRAYWELD and FUSEWELD processes. This datasheet provides information on composition, physical properties, hardness, elasticity, and compressive strength as well as fracture toughness. It also includes information on high temperature performance and corrosion resistance as well as forming, heat treating, and powder metal forms. Filing Code: Co-74.
