4140 steel flat bars: 4140 Steel In Metal Sheets & Flat Stock for sale | OTAI
What is 4140 steel
4140 steel is a cold drawn annealed steel of relatively high hardenability with its chromium content providing good hardness penetration, and the molybdenum imparts uniformity of hardness and high strength.
4140 alloy steel well to heat-treatment and is relatively easy to machine in the annealed condition. 4140 steel has good strength and wear resistance, excellent toughness, coupled with good ductility, and the ability to resist stress at elevated temperatures.
