AISI/SAE 4340 Alloy Steel Bar

Carbon Steel Bar：

Carbon steel round steel is a steel with a carbon content greater than 0.08%, and is one

of the most widely used materials in the construction industry. Commonly used materials include A36/S355JR/1018/1025/4130/EN8 etc.

AISI/SAE 4340 Alloy Steel Bar

AISI 4340 carbon steel bar is made of a heat treatable low alloy steel containing chromium, nickel and molybdenum. It has high toughness and high strength under heat treatment conditions.

AISI/SAE 4340 Alloy Steel Bar Description

AISI 4340 is a commonly used alloy steel with high strength, high toughness, good wear resistance and corrosion resistance. Its moderate carbon content gives it good machinability and weldability. In addition, it also contains appropriate amounts of chromium, nickel and other elements, which further improves its performance. At the same time, its toughness and ductility are also quite good, and it can maintain good performance even in both high or low temperature environments. Due to the excellent physical and mechanical properties of 4340 steel, 4340 steel bars are also widely used in equipment manufacturing in corrosive environments such as petroleum, chemical industry, and ships.
