High External Strength, Good Internal Strength 8620 Round Bar
The 8620 round bar is a popular steel grade for making bars. It is known for its high tensile strength of 86,200 psi, excellent machinability, and malleability. This type of steel is used for various purposes, such as making axles, gears, shafts, screws, bolts, and other fasteners.
The benefits of 8620 alloy steel are numerous. This type of steel is made of manganese, nickel, and chromium, which makes it highly durable. It has a high strength-to-weight ratio and can be used in various applications, including automotive parts, structural beams, gears, and more.
Moreover, the 8620 alloy steel is low-carbon steel with a high strength-to-weight ratio. It is easy to machine and weld and resistant to atmospheric and general corrosion, making it ideal for projects that require long-term use in corrosive environments. It is commonly used in structural supports, axles, gears, shafts, and couplings.
The 8620 round bar has some advantages over other steel bars. First, it is easier to machine due to its low hardness. Second, it is more accessible to weld because of its low carbon content. Third, it has a good balance between strength and toughness.
The 8620 alloy steel is characterized by a hard outer case with a soft, ductile core, making it highly wear-resistant. It is also flexible during hardening treatments, responds well to polishing, and has good machinability. However, it will not respond satisfactorily to induction hardening due to its low carbon content. Nitriding can further surface harden this type of alloy steel.
