Piyush Steel Round Bars has increased its stockholding of Grade AISI 4140 Alloy Steel Round Bars so it can better serve customers requiring high temperature resistant steel for furnaces and other similar applications.

Looking for AISI 4140 Alloy Steel Round Bars in various sizes and choice of finishes? AISI 4140 grade carbon steel is an excellent carbon steel option with great thermal and physical properties compared to similar steel grades. Piyush Steel carries AISI 4140 Alloy Steel Round Bars in all shapes including rounds, hexagons, squares and flats, and we can cut the round bars into your desired lengths.

AISI 4140 Alloy Steel Round Bars are one of our stock held items and can be delivered worldwide. AISI 4140 Alloy Steel Round Bars are produced by a combination of the techniques of rolling and forging. While the bars are being forged they are continuously rotated to create an even surface across the bar. This has the benefits of having the precision engineering required from a rolled bar and the strength provided in a forged bar.

Stocks of the most popular sizes ranging from 5mm to 25mm have been boosted to improve delivery times and help ensure highly competitive prices. Buy standard stock of AISI 4140 Alloy Steel Round Bars or cut your material to length online for low trade prices, select the size and length AISI 4140 Alloy Steel Round Bars you require using the dimension table. With a high amount of carbon, AISI 4140 Alloy Steel Round Bars is commonly used for applications where flame hardening is utilized for surface hardness. The properties of AISI 4140 steel make it ideal for many quench and temper heat treatment, forming and machining uses.

AISI 4140 Steel Bar, Steel Plate, Flats Supplier, Stockist and Exporter. AISI SAE 4140 alloy steel is a chromium molybdenum alloy steel specification widely used in general purpose high tensile steel for components, like axles, shafts, bolts, gears and other applications. Similar to alloy grade AISI 4130 chrome moly alloy steel but with a slightly higher carbon content. The higher carbon content of AISI 4140 steel gives greater strength and heat treatment capabilities in comparison to AISI / ASTM 4130 alloy steels, however it does have inferior weldability characteristics.
