Steel Grades:

AS/NZS 1163:
– Steel Grades: AS/NZS 1163 defines different steel grades, such as
*AS NZS 1163 C250 CHS;
*AS NZS 1163 C350 CHS;
*AS NZS 1163 C450 CHS.
The numerical designation corresponds to the specified minimum yield strength of the steel.
– Chemical Composition: The standard stipulates specific chemical composition requirements to ensure that the steel possesses the necessary mechanical and structural properties.

*L0 designation indicates guaranteed impact strength properties at 0°C.
