AS 1163
AS/NZS 1163 is the 호주/뉴질랜드 표준 for Cold-formed structural steel hollow sections. This Standard specifies the requirements for the production and supply of cold-formed, electric resistance-welded, steel hollow sections used for structural purposes. It considers three strength grades, with or without impact properties, that are suitable for welding. This Standard applies to structural hollow sections formed cold without subsequent heat treatment. The purpose of AS 1163 standard is to provide manufacturers and suppliers with a uniform method of specifying the requirements for the production of cold-formed, electric resistance-welded, steel hollow sections. The dimensions, tolerances, and other relevant properties specified in this Standard are those appropriate to current manufacturing capabilities and practices. This Standard is not intended to convert non-compliant steels into grades that meet the requirements of this Standard. However, nothing in this Standard shall be taken to prohibit the use of lower grades of material than those specified if such use can be shown to be consistent with good engineering practice. In particular, nothing in AS/NZS 1163 standard precludes the formation of cubic or non-circular shapes from material complying with the dimensional tolerances specified herein by methods.
Steel Grades of AS/NZS 1163 Pipes
The grade designation (for example, C250) is based on the steel’s nominal minimum yield strength (in MPa). To indicate that the section is cold-formed, the prefix ‘C’ is used before the value of the nominal yield strength of the steel. AS1163 only takes into account cold-formed structural steel hollow sections. As specified in AS1163, the suffix ‘L0’ denotes impact properties at 0°C.
Examples :
AS / NZS 1163-C350
AS / NZS 1163-C350L0
where
AS / NZS 1163 = number of this Standard
C = cold – formed sections
350 = minimum yield strength in MPa ( see Table 7)
L = guaranteed impact properties of the material ( when applicable )
0 = low temperature impact test at 0C( when applicable )

Chemical Composition of AS 1163 Materials
As per the AS1163 standard, sampling methods for chemical analysis must be in accordance with AS/NZS 1050.1 or ISO 14284. This is to ensure that the results of the analysis are accurate. The accuracy of the results is essential in order to make decisions about the quality of the product. AS/NZS 1050 series Standards or other procedures that achieve the same, or better, degree of accuracy must be used in order to determine the chemical composition. This is because it is important to have reliable information about the chemical composition in order to make decisions about the safety and quality of the product.

Mechanical Properties of AS/NZS 1163 Materials
Tensile tests, impact tests, and flattening tests are very important when measuring the mechanical properties of AS1163 materials. These tests help determine the material’s ability to resist forces that can cause it to break or deform. The tensile test measures a material’s ability to withstand pulling forces, while the impact test measures its resistance to shattering forces. The flattening test, meanwhile, assesses a material’s ability to resist crushing forces. Each of these tests is essential for understanding the overall strength and durability of AS1163 materials. By assessing the results of these tests, engineers can ensure that these materials will be able to perform as intended in a variety of applications.
Tensile testing is an essential process for determining the strength and properties of materials. In order to ensure accurate results, it is important to follow the guidelines set out in AS 1391. This standard specifies the rate of straining that should be used when approaching the yield strength, as well as the limits for the conventional straining rate. In addition, the impact test specified in AS 1544.2 must be carried out on each of the three test pieces prepared from each sample. These tests are essential for ensuring the safety and quality of materials.

The tolerances of AS 1163 Standard
The tables given below show the dimensional and mass tolerances for AS1163 cold-formed hollow sections. 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.
