4340 steel


 Our billet steel rods are made from 4340 steel. This is often referred to as an “aircraft” grade alloy because of its superior strength and durability. Steel that meets Iron and Steel Institute (AISI) 4340 standards contains 1.65 to 2.0% nickel, 0.70 to 0.90% Chromium, 0.60 to 0.80% manganese, 0.20 to 0.35% silicon, and 0.20 to 0.30% molybdenum. The addition of these elements to the steel give it hardness, toughness, ductility and fatigue resistance. Are the most useable rods we offer, as material to cost ratio offers great rod, for lower budget applications.
