Materials resist damage by abrasion or erosion, and protect underlying surfaces from abrasive or erosive wear.Įvaluated for alternative or renewable energy production products such as photovoltaic (PV) cells, solar power systems, wind turbines, hydro turbines, and flywheel power systems. Certified aircraft quality steels have paperwork indicating the alloy is what it is supposed to be and what steel mill produced the product. Aircraft quality alloys are also used in non-aerospace applications for highly stressed, mission critical components involving additional stringent inspection requirements such as macro-etch limits, magnetic particle, or other NDT tests for inclusions or other defects.
Mission critical and highly stressed aircraft parts are fabricated from aircraft quality (AQ) steel alloys. Aircraft quality (AQ) steels and alloys are manufactured to aerospace industry AMS 2301 standard specifications of cleanliness, chemistry, strength, and mill traceability as well as exacting steelmaking, rolling, and testing practices. Products are designed and rated for use in aerospace, aircraft, airport, space vehicle, satellite, rocket, interplanetary explorer, and space station applications. Materials with a higher modulus of elasticity have higher stiffness or rigidity. Tensile modulus, Young's modulus, or the modulus of elasticity (E) is a material constant that indicates the variation in strain produced under an applied tensile load. Ductile materials typically deviate from Hooke's law or linear behavior at some higher stress level.Įlongation is the percent amount of deformation that occurs during a tensile test or other mechanical test. Yield strength (YS) is the maximum amount of stress required to deform or impart permanent plastic deformation (typically of 0.2%) in the material under tension-loading test conditions. The yield point occurs when elastic or linear stress-strain behavior changes to plastic or non-linear behavior. Ultimate tensile strength (UTS) at break is the maximum amount of stress required to fail or break the material under tension-loading test conditions. This is the length of stock materials such as bars, rods, plates, and tubes. This is the overall width or outer diameter (OD) of stock forms such as bars, plates, and tubes. Overall width is the average particulate diameter for raw materials such as powders, granules, and pellets. Different gauge systems are used for different stock forms and alloy types. The numerical gauge thickness of the sheet, foil, or wire product. Products returned as matches will meet all specified criteria. User may specify either, both, or neither of the "At Least" and "No More Than" values. This is the overall thickness of stock forms, tube walls, or other fabricated components.
