30CrMnSi alloy steel is specially designed and manufactured to meet the production of various important parts that require high load and high-speed capabilities. It has high strength and toughness, high hardenability, medium cold deformation plasticity, good processability, the tendency to temper brittleness, and poor transverse impact toughness. The weldability is good, but when the thickness is greater than 3mm, preheating should be done before welding, and heat treatment should be carried out in time after welding. Generally used after conditioning.

30CrMnSi alloy structural steel is mainly used to manufacture key components that bear heavy loads and rapid movement: axles, gears, sprockets, clutches, bushings, bolts, nuts, etc.

Production Process


 Product Process

30CrMnSi alloy steel plates of production process

Smelting and Casting: The raw materials undergo a smelting and casting process to melt and cast them into alloy billets. This process requires high-temperature furnaces and casting equipment.

Heat treatment: Alloy steel billets undergo heat treatment processes, such as quenching, tempering, etc., to improve their mechanical properties and organizational structure. This process requires heat treatment equipment and control systems.

Rolling and processing: The heat-treated alloy steel billet undergoes rolling and processing processes to turn it into steel plates of suitable size and shape. This process requires rolling mills, cutting machines, drilling machines, and other equipment.

Surface treatment: The steel plate undergoes surface treatment processes such as pickling, rust removal, and spraying to improve its surface quality and corrosion resistance.

Testing and quality control: Various testing and quality control are required during the production process, such as chemical composition analysis, mechanical property testing, dimensional testing, etc., to ensure that the product meets standard requirements.

Packaging and shipment: Finally, the alloy steel plates are packaged and labeled, ready for shipment from the factory.
