Austenitic stainless steel is a specific type of stainless steel alloy.
 Stainless steels may be classified by their crystalline structure into three main types: "austenitic", "ferritic" and "martensitic".
Overhoff Technology Corp is a subsidiary of US Nuclear Corp, (OTC BB: UCLE) based in Milford, Ohio that designs, constructs, and sells radiation monitoring equipment.
 Their product line includes tritium monitors (an Overhoff specialty), heavy water leak detectors, gamma survey meters, environmental ion chambers and neutron dosimeters which are used to detect radioactive tritium in air, water and ground sources.
A superalloy, or high-performance alloy, is an alloy that exhibits several key characteristics: excellent mechanical strength, resistance to thermal creep deformation, good surface stability, and resistance to corrosion or oxidation.
 The crystal structure is typically face-centered cubic austenitic.
 Examples of such alloys are Hastelloy, Inconel, Waspaloy, Rene alloys, Haynes alloys, Incoloy, MP98T, TMS alloys, and CMSX single crystal alloys.
XIO Strategies (XIO) is a supply chain management and communications consulting firm, headquartered in Vienna, Virginia.
 XIO provides consulting services in areas such as business process analysis, program management, technology deployment, technical writing, systems training and communications program development.
 In January 2011 Cubic Corp. announced plans to purchase XIO Strategies, making the company part of Cubic Global Tracking Solutions, which Cubic formed in 2010 when it acquired Impeva Labs.
A micellar cubic phase is a lyotropic liquid crystal phase formed when the concentration of micelles dispersed in a solvent (usually water) is sufficiently high that they are forced to pack into a structure having long-ranged positional (translational) order.
 For example, spherical micelles a subic packing of a body-centred cubic lattice.
 Normal topology micellar cubic phases, denoted by the symbol I, are the first lyotropic liquid crystalline phases that are formed by type I amphiphiles.
 The amphiphiles' hydrocarbon tails are contained on the inside of the micelle and hence the polar-apolar interface of the aggregates has a positive mean curvature, by definition (it curves away from the polar phase).
 Inverse topology micellar cubic phases (such as the Fd3m phase) are observed for some type II amphiphiles at very high amphiphile concentrations.
 These aggregates, in which water is the minority phase, have a polar-apolar interface with a negative mean curvature.
 The structures of the normal topology micellar cubic phases that are formed by some types of amphiphiles (e.g. the oligoethyleneoxide monoalkyl ether series of non-ionic surfactants are the subject of debate.
 Micellar cubic phases are isotropic phases, but are distinguished from micellar solutions by their very high viscosity.
 When thin film samples of micellar cubic phases are viewed under a polarising microscope they appear dark and featureless.
 Small air bubbles trapped in these preparations tend to appear highly distorted and occasionally have faceted surfaces.
Gloria Material Technology Corp. (or GMTC) headquarter is located in Liuying industrial zone, Tainan City, Taiwan, and is the only specialty alloys professional manufacturer in Taiwan which owns Melting, Forging, Rolling, Heat treating and finishing process.
 GMTC provides more than 500 steel grades such as Superalloy, Titanium alloy, ESR & VAR steel, High speed steel, Stainless steel, quenched-tempered steel, Tool steel, special steel profile and precision parts machining.

DIN 1.2344 tool steel (also known as AISI H13 steel or just H13) is a tool steel grade standardised for hot working.
 The main feature of this grade is the combination of alloyed elements of chromium, molybdenum and vanadium, Cr-Mo-V, which provides a high wear resistance to thermal shock.
 It is well known as for its great strength, and heat resistance.
 It is heavily used for die casting in the cold heading field.
Surgical stainless steel is an informal term which refers to certain grades of stainless steel that are used in biomedical applications.
 The most common "surgical steels" are austenitic 316 stainless and martensitic 440 and 420 stainless steels.
 There is no formal definition on what constitutes a "surgical stainless steel", so product manufacturers and distributors apply the term to refer to any grade of corrosion resistant steel.
EISOO Information Technology Corp. is a cloud computing company, dealing in the areas of enterprise–grade file sync& sharing, data protection (backup, disaster recovery and virtualization management) and managed cloud service.
 It provides a comprehensive solution for business to ensure both system availability and secure content management.
 EISOO was founded in 2006 and its headquarters is in Shanghai, China.
Waspaloy is a registered trademark of United Technologies Corp that refers to an age hardening austenitic (face-centred cubic) nickel-based superalloy.
 Waspaloy alloy is typically used in high temperature applications, particularly in gas turbines.
