The 2% yield strength is is 29ksi with an elongation before break of 39%. ![]() Relatively speaking it is very easy to shape cold, but has very poor corrosion resistance and a very low yield strength. Types of Armour Metal Commonly Available in India Types of Armour Metal Commonly Available in Ukraine/Russia Types of Armour Metal Commonly Available in the USAįull Hard 301 Stainless Steel (Pre-Hardened) ![]() ~ = I'm guessing at the yield strength based on the most similar material that that I can find a material data sheet for. Titanium - OT-4 (Russia/Ukraine) 99ksi / 18% EBB (171ksi adjusted for density) Titanium - Grade 2 / "Pure titanium" (USA) 49ksi / 28% EBB (85ksi adjusted for density) Titanium - Grade 5 / 6Al-4V (USA) 128ksi / 14% EBB (227ksi adjusted for density) Quick Reference for Yield Strength and Ductility:ġ050 Carbon Steel / C50 / ST50 at Rc39 ~150ksi / ?% EBBĤ130 / (EN) 25CrMo4 at Rc48 208ksi / 11.5% EBBĦ5G / GOST 65 (Russia/Ukraine) ~155ksi / ?% EBBģ0HGSA / 30KhGSA (Russia/Ukraine) 192ksi / ?% EBBĤ10 Stainless Steel at Rc45 156ksi / 12% EBBġ7-7ph Stainless Steel (USA) 150ksi / ?% EBBįull Hard 301 Stainless Steel 140ksi / 9% minimum EBBġ7-4ph Stainless Steel (USA) 150ksi / 11% EBB Based on results seen with 4130 and 17-7ph stainles steel I'd recommend 11.5% for body and 13% for helmets. ![]() In my opinion the absolute minimum lab measured elongation for break for the material at the heat treatment that you are using should be 10%. One rule of thumb that I've developed is for how ductile the steel used for full contact armoured combat sport armour should be.
