C350L0

AS1163 C350L0 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 C350L0 means cold-formed structural steel hollow sections with 350 MPa minimum yield strength, and it must meet the impact test requirements. To achieve such high yield strength in such thin-walled structures, special manufacturing processes are required, which makes them more expensive than other grades of steel. However, their superior strength and durability make them ideal for use in construction, especially in areas where high winds or seismic activity are a concern.

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 steel hollow sections used in construction meet these minimum requirements, AS1163 helps to ensure the safety and durability of buildings and other structures. As a result, this Standard plays an essential role in protecting the public from the potentially devastating consequences of construction failures.
