Rationale: A material of high fracture toughness is low-risk for fracture. By looking at 304 stainless steel properties, it’s clear to see why it’s used in so many applications. 2” Elongation % A 50-85 60-90 20 B 70 80 20 Chemical Composition The following composition properties are ASTM specifications for A710 grades. 304 Stainless Steel Properties The World's most comprehensive professionally edited abbreviations and acronyms database All trademarks/service marks referenced on this site are properties of their respective owners. Search for materials by name or properties. Alternatively, to obtain the highest mechanical properties from the alloy, Condition A material is transformed to martensite at the mill by cold reduction to Condition C. Hardening to Condition CH 900 is accomplished with a single, low-temperature aging heat treatment. It’s a versatile steel, and comes with many advantages, making it a popular choice with designers and manufacturers alike. The material finds use in applications requiring high strength, paired with corrosion resistance up to 1300 °F (700 °C). c) FTU+FTY are greater or … 5->I i. u e VA HANDBOOK 7125 PART 1. Stainless Steel A286 is a precipitation-hardenable super-alloy based on iron. For example: You have a process of that is divided into four sub-processes – A, B, C and D. Assume that you have 100 units entering process A. c. The Chief, A&MMS, will ensure Engineering Service is aware of all property placed in use. When purchasing the material, you should receive a test report with the traceability data. Temp Coefficient of Expansion* Thermal Conductivity Electrical Resistivity °F 10-6 in/in •°F Btu•in/ft 2 •h•°F ohm•circ mil/ft 70 - 88 547 200 9.09 97 - 400 9.16 112 - 600 9.42 126 - 800 9.61 140 - This should confirm that: a) composition of the ordered material is identical to that tested in MMPDS b) heat treatment is the same as the MMPDS samples. Material Properties The following material properties are ASTM specifications and will be confirmed on the Mill Test Report. Definition of First Time Yield (FTY): The number of good units produced divided by the number of total units going into the process. Grade Yield Point (ksi) Tensile Strength (ksi) Min. Steel, in the most basic terms, is refined elemental iron mixed with carbon to form a stronger material. Physical Properties Mechanical Properties Thermal Properties Other Designations Fabrication Applications. However, there are thousands of different forms of steel, as it is a chemical process with dozens of possible chemicals added for specific properties. Exception: devices needed to assist an employee due to a disability or impairment. It’s used in a wide range of engineering sectors. Immediately temper at 150-370°C to obtain a wide variety of hardness values and mechanical properties as indicated in the accompanying table. Corrosion Resistance: ... a high-purity aluminium / aluminum 6000 or 7000 series alloy to provide physical and electrolytic protection to the key material, and thereby increasing resistance to corrosion. To: Metallic parts have a material property ratio of KIc/Fty ≥ 1.66 √mm (0.33 √in) and do not have sensitivity to EAC, SLC, or stress corrosion cracking as defined in NASA-STD-6016. Besides, the alloy has other favorable properties, including excellent fabrication characteristics, low-temperature non-magnetic strength [down to -320 °F (-196 °C)], and ductility. b. Thermal and Electrical Properties * Mean coefficient of linear expansion between 80°F (27°C) and temperature. Tempering in the range 425-565°C is to be avoided because of reduced impact resistance and corrosion resistance. The Government is not responsible for loss, service, or repair of property placed in use for the convenience of the employee. A free online materials information resource with properties data on over 28,000 materials.
