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.

Due to their design, Vibrophores have been used in the past solely as dynamic materials testing machines to determine durability with regard to fatigue life and fatigue limit, for example for fatigue testing to DIN 50100 (S-N curve) under tensile, compression, pulsating and alternating loads. The new generation of ZwickRoell Vibrophores can be used as both dynamic and full-fledged static materials testing machines that accommodate test loads up to 1000 kN. Typical applications are material fatigue tests and durability tests on standardized specimens and components (for example, piston rods, crankshafts, and screws) and production and quality control of components exposed to dynamic loads during their service lives, such as concrete and reinforcing steel, as well as quasi-static tensile and compression tests and fracture mechanics tests on CT and SEB specimens.

Our gold coated fiber is available for both wavelength ranges: from UV, VIS up to infrared wavelength ranges. The fiber offers excellent protection against chemical corrosion & mechanical stres and is capable of withstanding extreme temperatures and harsh environments. The fiber can be terminated directly onto the coating for hermetically sealed assembly. Our Gold coated fiber has very low outgassing of volatile components. We perform 100% stringend test procedures according to international standards. Typical applications are typically for extreme conditions such as: • Aircraft, missile, rocket, turbine & jet engine monitoring • Radiation, caustic & corrosive environments • Material fatigue sensing applications • High power laser delivery systems • Ultra high vacuum applications

heracle developes and produces specialty optical fiber with metal coating for application in harsh environments. Fiber types include Mutimode fiber with step or graded index profiles and Singlemode fiber. All fiber fiber types can be offered with either Gold or Aluminum coating. The pure fused silica step index multimode fibers (SIMM) are optimised for applications in the UV/VIS and VIS/IR wavelengths. The graded index Multimode fiber is designed to operate at 850nm and 1300nm. The Singlemode fiber is specified accoring to according ITU-T G.652. Metal coated optical fibers are typically used under extreme conditions such as: - Aircraft, missile, rocket, turbine & jet engine monitoring; - Radiation, caustic & corrosive environments - Material fatigue sensing applications - High power laser delivery systems - Ultra high vacuum applications
