AS/NZS 1163 C450
AS/NZS 1163 C450
Type of hollow section: AS/NZ 1163 C450 is made to the Australian standard for cold-formed structural steel hollow sections with a tensile test requirement. It is made to this standard. In grade C450 L0, there is a Charpy v-notch impact test that must be done. In grade C450, there is not.
When you make hollow sections of cold-formed steel, AS1163 C450 tells you what kind of steel you should use. When you figure out the grade of the metal, you use the steel’s nominal minimum yield strength (C450) (in MPa). When the value of the nominal yield strength of steel is written, “C” is the first letter. This shows us that this part has been cold formed. When you read AS 1163, you only have to follow this rule if you use cold-formed structural steel hollow sections.

NOTE: These restrictions apply to the face from which the tensile test is performed. That is, the usage of b/t or d/t ratio for RHS is determined by which face the test specimen is cut from. There is only one ratio for SHS (as b = d).
Shape and Weight Tolerances of AS/NZS 1163 C450 Pipes
Characteristic | Circular Hollow Sections | Square and Rectangular Hollow Sections |
External dimensions (do, d and b) | ±1%, with a minimum of ±0.5 mm and a maximum of ±10 mm | ±1%, with minimum of ±0.5 mm |
Thickness (t) | For do £ 406.4 mm: ±10% For do > 406.4 mm: ±10% with a max of ±2 mm | ±10% |
Out-of-roundness (o) | ±2% for hollow sections having a diameter to thickness ratio not exceeding 100 (Check Note 1) | — |
Concavity/convexity (Check Note 2) | — | Max. 0.8% or 0.5 mm, whichever is greater |
Squareness of sides | — | 90°±1° |
External corner profile | — | Check Table 5 |
Twist (v) | — | 2 mm + 0.5 mm/m length |
Straightness (Check Note 3) | 0.20% of total length | 0.15% of total length |
Mass (m) per unit length | Not less than 0.96 times the specified mass (Note 4) on individual lengths | |
NOTES:
- When the diameter to thickness ratio reaches 100, the producer and consumer must agree on the tolerance for out-of-roundness.
- Convexity and concavity tolerances are independent of external dimension tolerances.
- The straightness tolerance is applicable to straightness in any single plane.
- In the absence of any other condition, the indicated mass is regarded as the nominal mass.
Length Tolerances of AS/NZS 1163 C450 Pipes
Type of length | Range mm | Tolerance |
Random length | 4000 to 16000 with a range of 2000 per order item | 10% of the sections delivered may be less than the minimum for the ordered range, but not less than 75% of the minimum |
Mill length (or “unspecified”) | All | +100 mm –0mm |
Precision length | <6000 | +5 mm –0mm |
6000 ~ 10000 | +15 mm –0mm | |
>10000 | +5 mm, + 1 mm/m –0mm |
NOTE: The inquiry and order must specify the type of length desired as well as the length or length range, as applicable. Alternatively, length tolerances must be provided when the order is placed.
AS/NZS 1163 C450 / API 5L X52 Dual Specs Pipes
There is a lot of demand for dual-spec pipes, like AS/NZS 1163 C450 and API 5L X52 materials, which are in short supply. Mechanic and chemical tests are done to show that these materials meet these standards. API 5L and AS/NZS 1163 each have their own set of tests that must be done to make sure they meet their own tensile and fracture toughness standards. Hydrostatic pressure testing and non-destructive weld inspection are also done to find out how strong and safe the structure is.
