HPM® C 276 is a Nickel-Molybdenum-Chromium-Tungsten alloy with a high level of corrosion resistance. A low carbon content enables the alloy to resist intergranular corrosion at weld joints. These attributes make it an important alloy for the most severe chemical processing applications. such as use in metal diaphragms for aerospace sensors and burst discs. The alloy is readily formed from the annealed temper.All standard welding methods except oxy-acetylene can be used for joining. Available Sizes: HPM® C 276 is available from Hamilton Precision Metals as strip product in thicknesses From 0.0005” to 0.050” (0.0127 mm to 1.27 mm) and widths up to 12.0” (304.8 mm). The material conforms to ASTM B575 and UNS N10276.

SS 304L is an austenitic Chromium-Nickel stainless steel offering the optimum combination of corrosion resistance, strength, and ductility. These attributes make it a favorite for many mechanical switch components, and use in surgical instruments. Low carbon content reduces susceptibility to carbide precipitation during welding. The alloy is readily formed in the annealed temper.SS 304L may be joined by all commonly used brazing and welding methods including oxyacetylene. The corrosive resistance to acids is generally very good with the exception of halogen acids. Available Sizes: SS 304L is available from Hamilton Precision Metals as strip product in thicknesses from 0.0005” to 0.050” (0.0127 mm to 1.27 mm) in widths up to 12.0” (304.8 mm). It is also available in foil as thin as 0.000200” (0.00508 mm) in widths of 4.0” (101.6 mm) maximum. The material conforms to ASTM A240, ASTM A666, FED QQ-S-766, MIL-S-4043, UNS S30403.

SS 305 is an austenitic Chromium-Nickel stainless steel with excellent corrosion resistance, and is suitable for very severe cold forming operations. A high nickel content reduces the work hardening rate so that it can be formed into electronic components and remain non-magnetic. The alloy is readily formable and work hardens slowly.It has good resistance to nitric and sulfuric acid solutions although it will not resist halogen acids. The alloy can be satisfactorily welded, brazed, and soldered. Available Sizes: SS 305 is available from Hamilton Precision Metals as strip product in thicknesses from 0.0005” to 0.050” (0.0127 mm to 1.27 mm) in widths up to 12.0” (304.8 mm). It is also available in foil as thin as 0.000200” (0.00508 mm) in widths of 4.0” (101.6 mm) maximum. The material conforms to ASTM A240, QQS-766, and UNS S30500.

HPM® 455 is a precipitation heat treatable martensitic Stainless Steel. The composition provides a good combination of corrosion resistance and heat treated strength favorable for fatigue applications. The material is well suited for demanding spring devices The alloy has reasonably good forming characteristics in the annealed temper considering that it has a hardness of RC30. A significant radius is useful when bending is necessary in a fabrication. Cold working prior to the precipitation hardening treatment can drive finish strength up to 270,000 PSI (0.2% offset yield strength). The alloy retains a good strength through 800°F (Approx. 70% of room temperature). Resistance to stress – corrosion cracking is optimized by heat treating at 950°F. The overall corrosion resistant to normal atmospheric is equal to SS 430 with no staining. The alloy can be welded by resistance and inert gas shielded techniques. It also is suitable for brazing using a flux when possible.

Alloy 276 is a nickel-molybdenum-chromium superalloy with an addition of tungsten designed to have excellent corrosion resistance in a wide range of severe environments. The high chromium, molybdenum and tungsten contents make the alloy especially resistant to pitting and crevice corrosion in reducing environments while chromium conveys resistance to oxidizing media. The low carbon content minimizes carbide precipitation during welding to maintain corrosion resistance in as-welded structures. This nickel alloy is resistant to the formation of grain boundary precipitates in the weld heat-affected zone, thus making it suitable for most chemical process application in an as welded condition. Alloy 276 is widely used in the most severe environments such as mixed acid chemical processing, pollution control, pulp and paper production, industrial and municipal waste treatment, and recovery of sour oil and gas.
