ASTM-A514 Carbon steel plate

ASTM A514 is an ultra high strength quenched and tempered alloy structural steel plate, characterized by its maximum yield strength of 100 ksi grade. It can maintain high strength and necessary toughness even in thick sections by adding various alloying elements and strict heat treatment processes. Its main value lies in reducing structural weight and withstanding extremely high loads.

PRODUCT DETAILS

Product introduction

    ASTM A514GrQ is a high-strength quenched and tempered alloy steel plate developed by the American Society for Testing and Materials (ASTM), which must comply with ASTM A6/A6M General Technical Conditions and ASTM A370 Mechanical Testing Standards. This steel plate is designed for high load environments and is mainly used in the field of marine engineering, such as the manufacturing of gear racks for self elevating offshore drilling platforms, and has been certified by classification societies.
    Its chemical composition includes elements such as carbon (C: 0.10-0.19%) and manganese (Mn: 1.00-1.45%). It is produced using controlled rolling, controlled cooling, and quenching processes to ensure the cleanliness and mechanical properties of the steel. The standard thickness range is 80-152mm, of which the 120-150mm thickness specification can achieve a yield strength of 720-760MPa, a tensile strength of 830-880MPa, and a V-shaped impact energy of 90-150J. Different thickness steel plates are treated with quenching and tempering or controlled rolling+tempering processes to meet the special requirements of marine equipment for material strength.

Offshore wind power structure: a reinforcing material used as a tower or foundation support structure.
2、 Heavy Machinery
Construction machinery: suitable for components such as excavator boom and crane arm that require high fatigue resistance.
Mining equipment: used for manufacturing wear-resistant structural components such as crusher liners and conveyor supports.
3、 Energy and Chemical Industry
Pressure vessels: can be used to manufacture medium and low temperature pressure vessels under specific heat treatment conditions.
Oil and gas pipelines: as reinforced rings or flange connections for high-pressure transmission pipelines.
4、 Transportation and Communications
Special vehicles: such as heavy-duty structures such as mining truck frames and railway freight truck bogies.
Shipbuilding: Used for strengthening deck structures or side protection plates.
