AS1163 C450L0
TUSPIPE manufactures its products strictly in accordance with the AS1163 C450L0 standard. C450L0 steel pipes offer high strength, excellent impact resistance, and precise dimensional control, making them suitable for high-performance structural projects.
AS1163 C450L0
AS1163 C450L0 is a steel grade of hollow section steels specified in the AS/NZS 1163 standard. The nominal minimum yield strength of hollow sections is used to determine the grade classification (in MPa). The prefix “C” is used before the value of the nominal yield strength of the steel to indicate that the section is cold-formed. Only cold-formed structural steel hollow sections are covered by AS1163. Also, if the number is followed by a suffix “L0”, this steel grade must meet the impact test requirements. As a result, AS1163 C450L0 means cold-formed structural steel hollow sections with 450 MPa minimum yield strength, and it must meet the impact test requirements. By meeting these two criteria, AS1163 C450L0 assures that it is a high-quality steel grade that can be used in various structural applications.
AS1163 is an オーストラリア/ニュージーランド規格 that covers the requirements for cold-formed, electric resistance-welded, steel hollow sections used for structural purposes. It applies to structural hollow sections formed cold without subsequent heat treatment. The Standard considers three strength grades, with or without impact properties, that are suitable for welding. This Standard is important because it ensures that steel hollow sections used for structural purposes meet minimum requirements for strength, ductility, elongation, weldability, and fracture toughness. This Standard is essential for anyone who produces or uses steel hollow sections in structural applications. By setting minimum requirements, the Standard helps to ensure that the steel hollow section produced meets a basic level of quality. This gives producers and users confidence that the steel hollow sections they are using will meet the necessary standards. The Standard also provides a basis for testing and certification of steel hollow sections. This can give users further assurance that the products they are using meet the required standards. Overall, AS1163 is an important Standard that helps to ensure the quality of steel hollow sections used in structural applications.

The tolerances of AS1163 C450L0 Standard
AS1163 C450L0 cold-formed hollow sections are often used in load-bearing applications, and even small deviations from the nominal dimensions can lead to significant changes in performance. As a result, it is important to ensure that cold-formed hollow sections meet the tolerances given in the tables below. The first table is for shape and mass, while the second is for length. As can be seen, the tolerances are relatively tight, especially for mass. This is due to the fact that hollow sections are often used in load-bearing applications, and even small deviations from the nominal dimensions can lead to significant changes in performance. As a result, it is important to ensure that cold-formed hollow sections meet the tolerances given in the tables below. Doing so will help to ensure that they perform as intended and do not fail prematurely.
