AISI 4150 HOT ROLLED ANNEALED<br />
4150 grade is a medium-carbon, chromium-molybdenum steel. 4150 is also capable<br />
of good strength and wear resistance, has excellent toughness, good ductility and has<br />
the ability to resist stress and creep at prolonged high temperatures. In the annealed<br />
condition, machinability is improved.<br />
