4130 STEEL SHEETS MIL-S-6345A NORMALIZED Formerly MIL-S-18729C This chromium-molybdenum alloy is one of the most widely used aircraft steels because of its combination of weldability, ease of fabrication and mild hardenability. It will respond to heat treatment to high strength levels and yet, in the annealed condition, it has adequate strength for many applications. Used for the manufacture of parts and components. Tensile strength 75,000-85,000 PSI. Sheared to sheet and strip sizes listed below. Subject to availability of normalized sheet, annealed 4130 sheet may be substituted. Less 10% discount on 6 sheets 18" x 36" or 3 sheets of 18" x 72" per part number. If Mfg. Test Reports are required, there's a minimum $15.00 charge per order. Please indicate P/N 01-01133 in the Special Instructions Box during the checkout process. |
