30CrMnSi alloy steel structural sheet with GB/T 3077 standard

30CrMnSi Alloy Steel Description

GB/T 3077 30CrMnSi alloy structural steel is a high-strength quenched and tempered structural steel with high strength and toughness, high hardenability, medium cold deformation plasticity, and good cutting performance. 30CrMnSi alloy steel has good corrosion resistance, heat resistance, weldability and fabrication performance, which can prolong the service life and improve the safety and reliability of the structure. It is a steel plate used to build buildings and other important structures.

30CrMnSi alloy steel is a low-alloy steel that mainly contains elements such as carbon, silicon, manganese, chromium, aluminum, and sulfur. 30CrMnSi steel has excellent mechanical properties, high tensile strength and yield strength, high elongation, and good fracture toughness. The steel plate has excellent heat resistance, can resist corrosion under normal temperature, and can resist acid and alkali corrosion under normal conditions. The steel plate has good weldability and fabrication performance, can be welded and fabricated on site, and is not prone to shrinkage.

30CrMnSi alloy steel structural plates are usually used to build buildings and important structures, and can be used to make frames, shelves, beams, columns, wing walls and other structures. It can also be used to make auto parts, such as body, chassis, suspension, etc. In addition, it can also be used to manufacture mechanical equipment, such as bearing housings, brackets, joints, etc.
