Product Description
Carbon steel is divided into carbon structural steel, carbon tool steel, and free-cutting structural steel.
Carbon structural steel is divided into engineering construction steel and machine manufacturing structural steel;
According to the smelting method, it can be divided into open hearth steel and converter steel;
According to the deoxidation method, it can be divided into boiling steel (f), killed steel (z), semi-killed steel (b) and special killed steel (TZ);
According to the carbon content, carbon steel can be divided into low carbon steel (WC ≤ 0.25%), medium carbon steel (WC 0.25% - 0.6%) and high carbon steel (WC > 0.6%).
4130
This low alloy steel contains high amounts of chromium and is often referred to as chromoly. 4130 steel has good machinability, ductility, weldability and strength characteristics. It is used for many different industries including the automotive, aerospace and machining industries.
4340
This nickel-chromium-molybdenum alloy steel is a very high strength steel. It is sought after for its toughness and for being used as a steel that will be highly stressed.It is used in a variety of industries for different applications including the automotive, aerospace, and tooling industries.
