Machinability of this alloy is good in the annealed condition. In the heat treated and quenched condition machining is best limited to finish grinding. The 4140 that we offer for sale here on our website is in the Cold Drawn Annealed condition. Chrome-Moly Steel McMaster-Carr4130 alloy steel has a low carbon content that provides good weldability. It's often used for structural applications. Hardened Multipurpose 4140 Alloy Steel Rods These rods are hardened for increased abrasion and impact resistance. Also known as chrome-moly steel, 4140 alloy steel resists fracturing from repeated stress. Chrome-Plated Hardened 4130 Chrome Moly Round Bar - 4130 Chrome Moly - 4130 - 4130 Alloy Steel Round Bar includes the elements of Chromium and Molybdenum, and for this reason, it is commonly referred to as Chromoly. It is widely used in the Aviation and Racing Industries because it has an excellent strength to weight ratio, it is very malleable and it is very easy to weld. 4130 Chromoly, Alloy Steel Round Bar, is resistant to scaling and oxidation 4130 vs 4140 Steel Comparison - Capital Steel
