AS1163 C450 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 C450 means cold-formed structural steel hollow sections with 450 MPa minimum yield strength, and no impact test required. This makes it an ideal choice for a variety of applications, such as beams, columns, trusses, and piping. Thanks to its high strength and formability, AS1163 C450 is a versatile material that can be used in a wide range of projects.
AS1163 is an Australian/New Zealand Standard 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 ensuring that these products meet minimum standards, AS1163 helps to protect both consumers and producers from sub-standard products. In addition, the Standard helps to ensure that steel hollow sections are safe and fit for their intended purpose. As a result, AS/NZS 1163 is an important document that should be consulted by anyone involved in the production or use of steel hollow sections.
