AS1163 C350
TUSPIPE manufactures high-quality steel pipes according to the AS1163 C350 standard. C350 products are durable and high-strength, meeting the needs of various construction and engineering projects.
AS1163 C350
AS1163 C350 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 C350 means cold-formed structural steel hollow sections with 350 MPa minimum yield strength, and no impact test required. This makes it an ideal choice for a wide range of applications, including structural and mechanical engineering, as well as handrails, furniture, and display stands. Thanks to its high strength and versatile nature, AS1163 C350 steel is an essential material in today’s construction industry.
AS/NZS 1163 is an オーストラリア/ニュージーランド規格 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.

Chemical Composition of AS/NZS 1163 C350 Pipes
The method of sampling from AS/NZS C350 materials for chemical analysis is critical to ensure accuracy and compliance with AS/NZS 1050.1 or ISO 14284. The chemical composition must be determined accurately to avoid any potential issues with the quality of the final product. Several different methods can be used for sampling, but the most crucial factor is that the chosen method can produce results that are at least as accurate as those produced by the AS/NZS 1050 series Standards. In some cases, it may even be necessary to use a more advanced or specialized method to achieve the same degree of accuracy. Regardless of the chosen method, care must be taken to ensure that an accurate and representative sample is obtained.

Mechanical Properties of AS1163 C350 Materials
Engineers need to know the material properties of AS1163 C350 to understand how it will behave in various applications. That’s why tensile tests, impact tests, and flattening tests are so important. 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 AS/NZS 1163 C350 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.

The tolerances of AS1163 C350 Standard
The tables given below show the dimensional and mass tolerances for AS1163 C350 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. Meeting these tolerances can be challenging, especially for mass, but it is essential for ensuring that cold-formed hollow sections meet their required performance levels. Consequently, manufacturers of these products must have tight controls in place to ensure that their products meet the relevant tolerances.

AS1163 C350 / API 5L X42 Dual Specs Pipes
There is a significant demand for dual-spec pipes, such as AS1163 C350 / API 5L X42 materials, which are available in limited supply. Several mechanical and chemical tests are performed to show compliance with these material specifications. API 5L and AS1163 each require their own test techniques in order to guarantee compliance with their respective tensile and fracture toughness standards. Hydrostatic pressure testing and non-destructive weld inspection are also performed in order to determine the structural and pressure integrity of the structure.
