FAQs
Frequently Asked Questions
Here are some common questions and answers. If you still have questions, don’t hesitate to contact us.
1. What is Australian Standard AS 1163?
Specifies the technical requirements for cold-formed steel hollow sections for structural purposes, for the six grades of steel that are suitable for welding.
2. What is AS NZS 1163 Grade 350?
AS/NZS 1163 C350/C450 RHS is a range of structural and general-purpose cold formed electric resistance welded square and rectangular hollow sections. AS/NZS 1163 C350 RHS, These products are manufactured to meet the mechanical property requirements of both C350 and C450 and are suitable for welding and limited bending.
3. What are the properties of AS NZS 1163 Grade C350?
Produced by vacuum arc re-melting, C350 provides a very high strength nominally 350 ksi tensile (2415 MPa) with an above-average level of toughness. The alloy retains its tensile strength up to 450°C, and good notch impact is maintained down to minus 50°C and below.
4. What is AS NZS 1163 Grade C300 Steel?
C300 is an age hardenable (maraging) iron nickel stainless steel. C300 has exceptional strength, toughness and is resistant to crack propagation. C300 is used for tooling, transmission shafts, autosport components and light aircraft landing gear.
5. What grades are included in the AS NZS 1163 standard?
The standard AS NZS 1163 is included Grade C250, C250L0, C350, C350L0, C450, C450L0.
6. What is the difference betweenAS NZS 1163 C250 and C350 grade steel?
While grade AS NZS 1163 C250 is commonly used in most applications, there are a wide array of grades available for specific purposes. AS NZS 1163 Grade 350, for example, is stronger. Steel Grade 1045 is designed for high-heat applications such as gears or moving parts that have friction applied to them often.
