Standard Number:
A183-14 is the standard number assigned to this particular steel grade by the American Society for Testing and Materials (ASTM International). This standard specifies the requirements for carbon and alloy steel track bolts and nuts used in railroad track fastening systems.
Corresponding Applications:
A183-14 steel grade is primarily used in the railway industry for manufacturing track bolts and nuts. These components are crucial for securing railroad tracks and ensuring the safety and stability of train operations. A183-14 steel provides excellent strength, durability, and resistance to wear, making it suitable for this application.
Other potential applications of A183-14 steel grade include manufacturing of heavy-duty industrial equipment, machinery components, structural components, and automotive parts where high strength and toughness are required. However, it is important to consult the specific requirements and standards of the intended application before using A183-14 steel grade in non-railway applications.
