JIS G4304 SUS429 hot-rolled stainless steel plates and coils are highly versatile materials that offer exceptional corrosion resistance and welding properties. Derived from the 430 steel grade, SUS429 has been optimized for improved weldability while maintaining the robust performance characteristics required in various industrial applications.

Chemical Composition

The chemical composition of SUS429 is carefully balanced to ensure optimal mechanical properties and corrosion resistance. It comprises carbon (C) at a maximum of 0.12%, silicon (Si) and manganese (Mn) both limited to 1.00% or less, phosphorus (P) and sulfur (S) at 0.04% and 0.03% maximum respectively. The chromium (Cr) content ranges from 14.0% to 16.0%, while nickel (Ni) is limited to a maximum of 0.75%.

Mechanical Properties

SUS429 exhibits excellent mechanical properties, including a minimum yield strength of 258 MPa and a minimum tensile strength of 313 MPa. Its elongation rate is 44%, indicating good ductility, while the impact test ensures its ability to withstand sudden load changes.

Heat Treatment Status

SUS429 stainless steel plates and coils are typically heat-treated to achieve desired mechanical properties. Heat treatment methods such as solution and aging, annealing, and ausaging, among others, are employed to optimize the material's microstructure and performance. Heat treatment temperatures typically range from 1367°C to 1875°C.

Size Range

JIS G4304 SUS429 stainless steel plates and coils are available in a wide range of sizes to meet various industrial requirements. Standard sizes include 1219mm x 2438mm, 1219mm x 3048mm, and 1219mm x 6096mm, but custom sizes can also be produced to meet specific customer needs.

Impact Test

The impact test is a crucial aspect of SUS429's quality assurance. This test ensures that the material can withstand sudden impact loads without failing, making it suitable for applications where such loads are expected.

Main Application Scenarios

SUS429 stainless steel finds widespread application in various industries. In the construction sector, it is used for interior decoration, such as walls, ceilings, and stair railings, due to its excellent corrosion resistance. In the heavy oil combustion sector, it is a preferred choice for fabricating burners, combustion chambers, and chimneys due to its high corrosion and heat resistance. Additionally, it is used in the manufacturing of household appliances like refrigerators, washing machines, and ovens, where its corrosion resistance and aesthetic appeal are highly valued.
