Alloy Steel Round Bar 300M Var

The 300M VAR alloy steel round bar is a vacuum-arc remelted material that provides incredible strength and fracture toughness for high-load applications. This ultra-high-strength steel is primarily used for aircraft landing gear, driveshafts, and high-performance racing axles. The VAR melting process removes impurities, resulting in a cleaner steel with significantly improved transverse ductility compared to standard alloys. You would use 300M over 4340 when you require the highest possible tensile strength in a low-alloy steel.
