About SAE 4340 Round Bars
4340 alloy Round is generally supplied hardened and tempered in the tensile range of 930 – 1080 Mpa. Prehardened and tempered 4340 sheets of steel can be further surface hardened by flame or induction hardening and by nitriding. The 4340 steel has good shock and impact resistance as well as wear and abrasion resistance in the hardened conditions. All SAE 4340 Rounds are designed and developed in accordance with IQS (International Quality Standards). Our SAE 4340 Rounds are made with precision using the best quality raw materials
