Depending on the polymer flow environment, the firm offers the following base materials: 4340 HT carbon steel, hardened alloy-welded flights; nitralloy
135m; CPM 10 v high chromium tool steel; D-2 tool steel; hastelloy; inconel; and stainless (300/300 series).
It's not unusual for Strite to work with materials such as carbon steels hardened to 58/62 [R.sub.c]; stainless steels, such as 17-5 PH and 13-8 PH; 304; hasteloy; titanium; zircalloy; beryllium; copper; hymu-80; Inconel[R]; macro ceramics; nitralloy
; nitrol and other more-exotic materials.
Materials are Nitralloy
, 52100, 440C, 4340 and 15-5 stainless.
The Coates rotary valves are fashioned from Nitralloy
, and the face of the seal is made from a proprietary carbon-ceramic alloy.
Depending on the severity of the polymer flow environment, the company offers packages manufactured from a variety of base materials, including carbon steel with hardened alloy welded flight lands, nitralloy
, high chromium tool steel, tool steel, hastelloy, inconel and stainless steel.
Other metals that exhibit toughness such as Inconel, Monel, Hastelloy, Nitralloy
, Waspaloy, Nimonic, and Udimet benefit because EDM is a noncontact process and there is no adhesion of workpiece to the tool.
Standard base material is 4140 heat treated steel, with available options including 4340 heat treated steel, Nitralloy
135M and all grades of stainless steel.
Materials are mostly Nitralloy
Cr/Mo/Al steels, tough and very prone to work hardening, as well as cast iron parts.
Barrels are available in such materials as Nitralloy
135-nitrided, tool steels, D-2, CPM-10V, CPMT-440V, iron boron (bimetallic), carbide (bimetallic) and nickel (bimetallic).
and molds made of hardened steels, tungsten carbide, high-speed steel, and exotic materials like Hastelloy, Nitralloy
, Waspaloy, and Nimonic, used in aeronautical and aerospace applications.
bushings are special steel alloy bushing that has been nitrided to a case depth of 0.015[inches] to minimum 68 Rc, resulting in a tough, wear-resistant surface.
The nomogram can be used to determine speeds and feeds for milling as well as machining materials such as Hastelloy, Incoloy, Monel, Nitralloy
, Rene, stainless, Udimet, Waspaloy, and toolsteels where little or no work has been done to date.
