Flash Bainite is a new form of steel developed by Bainsteel. According to the manufacturer specs it is the Strongest, Most Ductile, Lean Alloyed, Readily Weldable, Least Expensive Ultra Strength METAL yet fabricated.
A50 tensile ranges from 1100 to 2080MPa (160-302ksi) with 8 to 9% elongation.
Flash 4130 at 1900MPa and 9% elongation exceeds titanium-6Al-4V's strength to weight ratio making it weight for weight stronger at only 56% the volume.
Flash 4130 is just 10% the cost of Ti-64.
