Best Price Alloy Steel Bar 20CrV 50CrVA 40CrNi 20MnMoB 38CrMoAlA 40CrNiMoA Carbon Steel Round Rod

Alloy steel bars 20CrV, 50CrVA, 40CrNi, 20MnMoB, 38CrMoAlA and 40CrNiMoA are usually used to manufacture parts with high strength, high wear resistance and high toughness. These alloy steel materials have different alloy compositions, giving them specific mechanical properties and uses.

20CrV: Contains alloying elements such as chromium and vanadium, provides good hardening ability and strength, and is suitable for the manufacture of parts requiring high strength and wear resistance.

50CrVA: Contains alloying elements such as chromium and vanadium, provides high strength and good toughness, and is suitable for the manufacture of parts requiring high strength and impact toughness.

40CrNi: Contains alloying elements such as chromium and nickel, provides good hardening ability and high strength, and is suitable for the manufacture of parts requiring high strength and wear resistance.

20MnMoB: Contains alloying elements such as manganese, molybdenum, and boron, provides good impact toughness and hardening ability, and is suitable for the manufacture of parts requiring high strength and impact toughness.

38CrMoAlA: Contains alloying elements such as chromium, molybdenum, and aluminum, providing high strength and wear resistance, suitable for the manufacture of parts requiring high strength and wear resistance.

40CrNiMoA: Contains alloying elements such as chromium, nickel, and molybdenum, providing high strength and good toughness, suitable for the manufacture of parts requiring high strength and impact toughness.

These alloy steel bars usually require proper heat treatment to achieve the required mechanical properties. In addition, surface treatment is also important to ensure its corrosion resistance and appearance quality.

If you need more detailed information, it is recommended to consult a material expert or supplier for detailed information on the specific specifications and uses of these alloy steel bars.
