National India. Co (India) is a one of the recognized Stockiest and Suppliers of AISI 4340 Alloy Steel Round Bars, which contains low carbon content, and subsequently it can be welded easily. AISI 4340 Bars is forged at a begin temperature of around 2200 Degree F (1205 Degree C) and could be forged down to roughly 1700 Degree F (925 Degree C). The general forging and finishing temperatures of AISI 4340 Rods will depend on a various factors, including overall reduction during forging and complexity of part being forged. AISI 4340 Flat Bars lacks suitable alloying elements and therefore does not respond to the nitriding procedures. AISI 4340 Square Bars can be easily welded by all the conventional welding processes. AISI 4340 Threaded Bars can also be heat-treated for their increased strength, durability, and electrical conductivity. Due to their fine finish, super performance and sturdy construction, those offered scope of AISI 4340 Hexagonal Bars are high in demand among our valued customers. These AISI 4340 Triangular Bars are used in the manufacturing process of those pipes.

AISI 4340 Hollow Bars are well known for its Rugged construction, Resistant to corrosion, Optimum performance, Sturdy construction, High performance, and many more. These UNS G43400 Round Bars are offered in variety of dimensions, thickness and tolerances in order to meet the fluctuated demands of the customers. The capacity to age harden of AISI 4340 Alloy Steel Rods makes it a best choice for applications such as springs and fasteners.

You can get the exact material according to your requirement at the least possible price. We also provide Reworks, FOB, CFR, CIF, and door to door delivery prices. The materials we offer are completely verifiable, right from raw material test certificate to the final dimensional statement. E-guarantee to give a response within 24hours working hours (usually in the same hour).You can also get stock alternatives, mill deliveries with minimizing manufacturing time.
