.Ultrasonic inspection of Alloy steel bar 4340: 100% ultrasonic inspection for any inperfections or based on the customer's requirement
Principal Design Features of Alloy steel bar 4340 Alloy steel bar AISI 4130 is a low alloy steel containing molybdenum and chromium as strengthening agents. The carbon content is nominally 0.30% and with this relatively low carbon content the alloy is excellent from the fusion weldability standpoint. The alloy can be hardened by heat treatment.
Applications of Alloy steel bar 4340 Typical applications foralloy steel bar 4130 low alloy steel include. structural use such as aircraft engine mounts and welded tubing applications.
