Distinguish Between 4140 And 4130 Steel Materials - China

The chemical composition of 4140 steel and 4130 steel is very similar, but the allowable residual content ranges of nickel and copper elements are quite different.

The nickel and copper elements of 4140 steel are ≤0.30, and the nickel and copper elements of 4140 steel are ≤0.030, and AISI 4130 alloy steel contains chromium and molybdenum as reinforcements.

It has low carbon content, so it is easy to weld; in terms of mechanical properties, its elongation δ5 (%), impact energy Akv (J), impact toughness value αkv (J/cm2) The range is the same; in the application In terms of alloy structural steel AISI 4140, it is used to manufacture forgings that require higher strength and larger quenched and tempered sections than 35CrMo steel, such as large gears for locomotive traction, supercharger transmission gears, rear axles, salvage tools, and bending machines.

molds, etc.

AISI 4130 is mainly used in medium-sized machinery manufacturing to manufacture quenched and tempered parts with large cross-sections that work under high stress conditions, such as shafts, spindles, bolts, gears, etc.

; in the chemical industry, it is used to manufacture welded parts, plates and pipes The welded structure formed and the high-pressure conduit whose temperature does not exceed 250 celsius in the medium containing nitrogen and hydrogen; used in the steam turbine and boiler manufacturing industries to manufacture fasteners working below 450 celsius, flanges and flanges under high pressure below 500 celsius Flange cover.

From this point of view, 4140 steel is quite similar to 4130 steel, but we will find the difference if we understand it carefully, so before buying steel, you must know your needs and find a professional supplier.

Our company has more than ten years of production experience, rich professional knowledge, cost-effective and high-quality products, and provides various types of alloy steel.

You are welcome to consult and purchase.
