AISI 4130 round bar specification, chemical composition and mechanical properties




Normalized vs annealed 4130 round stock
Normalized steel slows down the inner stress on steel. It helps improve toughness that hardens after the cold working process. Steel is warmed to a specific temperature. Then it is allowed to air cool, whereas annealing relieves internal stress. It softens the metal. It makes it more ductile. The metal is heated to a temperature and then cooled in a furnace.

Why AISI 4130 steel round bar is used?
The 4130 steel is used in edging and cutting applications. It is used for manufacturing equipment for bearings, vehicle parts, and gears, and it is also used for rock-crushing machinery. It is also used in resistance welding products. It is also used in drilling pipes and taps.A 4130 Steel Hexagonal Bar is used for automotive purposes. A 4130 Alloy Steel Polished Bar is an alloy bar that is heat treated by annealing. An AISI 4130 Steel Black Bar is completely solution-strengthened. They have excellent resistance. They can work even in acid-containing environments.

Difference between AISI 4130 60K, 75K, 80K, 85K round bar
The round bars vary in thickness, dimension, length, and size. The hardness HBW of 60k bar is 174-237. The hardness HBW of 75k bar is 197-235. SAE 4130 steel rods are excellent from the standpoint of fusion weldability. It can be hardened further by giving heat treatment. An AISI 4130 alloy steel round bar is an excellent quality steel bar. It has high hardness. It has high sensibility. Chromoly AISI 4130 ingot is low alloy steel. Chromium and molybdenum are their main elements.

Features of AISI 4130 forged bar
This type of steel has good strength and machinability. It also carries good weldability. It has good strength. It also stands for atmospheric corrosion. 4130 low alloy steel bars are formed from exceptionally well-welding steel. It is readily machined in a tempered state. AISI 4130 Forged Bar has chromium and molybdenum as its strengtheners. An AISI 4130 Chromoly shaft is made with 0.8 to 1.1 % chromium. It has good ductility. An SAE AISI 4130 billet has an equivalent grade of UNS G41300. It is used to make machine parts such as arms, rollers, gears, etc. it comes under alloy steel.
