A286 Fasteners
A286 Fasteners being an austenitic age-hardenable iron based super alloy stainless steel that is melted as AOD + ESR, AOD + VAR, or VIM + VAR is manufactured at TorqBolt. Cres-A286 fasteners have excellent strength even at high temperatures up to 1500 Degrees Fahrenheit. Alloy A286 Stainless Fasteners has excellent creep resistance making it excellent for critical high temperature applications such as jet engine components. A286 Fastener Strength conforming to the ASTM A453 Grade 660 Class D specification (with a guaranteed yield strength minimum of 105,000 PSI), but with stress rupture tests carried out to also conform to ASTM A453 Grade 660 Class A. These provide a tensile strength of 895 MPa (minimum), 0.2% offset yield strength of 725 MPa (minimum), elongation of 15% and reduction of area of 18%. Hardness is in the range 29-35 HRC.
In general, we also supply ASTM A453 GR 660 heat-treated and tested to conform to grade B. This provides a tensile strength of 895 MPa (minimum), a lower 0.2 offset yield strength of 585 MPa (minimum), elongation of 15% and reduction of area of 18%. Hardness is in the range 24-37 HRC.
