4330V Pump forging

Descripción del producto

AISI ***0V is a nickel-chromium-molybdenum-vanadium alloy steel that belongs to low-alloy high-strength structural steel.
As an improved version of ***0 alloy steel grade, ***0V improves hardenability by adding vanadium, and can obtain higher strength and low temperature impact resistance after quenching and tempering heat treatment.

***0V steel is suitable for parts subject to impact load or stress concentration. It is widely used in the oil and gas industry for applications such as oil tools, drill bits, tool holders and reamers, as well as bolted joints and air frames in the aerospace industry.

***0 is a type of low-alloy steel that can endure strong forces and severe environmental conditions. It consists of various rare elements, such as chromium, nickel, molybdenum and vanadium which render it highly resistant to wear, tear and corrosion. Moreover, the presence of vanadium strengthens its capacity for withstanding high stress environments.

***0 alloy is a combination of two major elements Manganese and Carbon, that come together to form its high strength and toughness. Silicon also has a part to play, as it helps to increase the hardness and strength even further. At the same time, phosphorus and sulfur are impurities that should be avoided or kept to an absolute minimum in order not to damage the properties of ***0 alloy.

For top-grade strength and durability, ***0 alloy steel is an excellent choice. 

The chemical composition of ***0 alloy is as follows:

• Carbon (C): 0.***0.*4%

• Silicon (Si): 0.***0.*5%

• Manganese (Mn): 0.*5 1.*0%

• Phosphorus (P): 0.**5% max

• Sulfur (S): 0.**0% max

• Chromium (Cr): 0.*5 1.*0%

• Nickel (Ni): 1.***2.*0%

• Molybdenum (Mo): 0.***0.*0%

• Vanadium (V): 0.***0.*0%

AISI ***0V STEEL FORGING

• Initial Forging Temperature：********0℃

• Final Forging Temperature：>**0℃

• Heating Rate:Strictly control the heating speed, which should be uniform and stable to prevent cracking caused by improper heating.

• Holding Time:Ensure that the material is fully and evenly heated,and the holding time should not be too long or too short.

• Forging Ratio：above 4:1

• Post-Forging Treatment:According to our experience, ***0V steel has extremely high sensitivity to white spots, so dehydrogenation annealing after forging is a necessary heat treatment process.
