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.

EN8 is a medium carbon steel with a carbon content of 0.25% to 0.60%. It is often used to manufacture mechanical parts, bearings, gears and other parts. It has high strength and wear resistance and can obtain high hardness and strength after heat treatment.

A572 steel bars have good strength, ductility and workability, making them ideal for structural applications. These characteristics make the A572 relatively simple to shape into different structures, while maintaining the ability to withstand large stresses and loads.

AISI 4130 carbon steel bar has excellent strength, toughness and processability. Through normalizing and quenching treatment, the steel can achieve high strength and strength. In addition, the bars have excellent weldability and forgeability.

8620 steel bar is made of a kind of low alloy steel mainly composed of iron, carbon, silicon, manganese, phosphorus, sulfur, chromium, nickel and other elements. It has good hardenability and weldability, and can obtain excellent mechanical properties through heat treatment.

1045 steel bar is made of a medium carbon, medium tensile strength steel, which has quite good strength, machinability and reasonable weldability under hot-rolled conditions. 1045 round steel can be provided with hot rolling, cold drawing, rough turning or turning and polishing.
