JIS G4304 SUS329J3L, a dual-phase stainless steel, is renowned for its exceptional corrosion resistance and mechanical properties. Derived from the latest standards set by the Japanese Industrial Standards (JIS), this material is specifically designed for applications requiring both strength and durability.

Chemical Composition

The SUS329J3L stainless steel boasts a balanced chemical composition that ensures its superior performance. Its key components include carbon (C) not exceeding 0.03%, silicon (Si) not exceeding 1.00%, manganese (Mn) up to 2.00%, phosphorus (P) and sulfur (S) both limited to 0.04% and 0.03% respectively. Chromium (Cr) ranges from 21.00% to 24.00%, nickel (Ni) from 4.50% to 6.50%, molybdenum (Mo) from 2.50% to 3.50%, and nitrogen (N) from 0.08% to 0.20%. This unique blend of elements ensures the steel's unique properties.

Mechanical Properties

The SUS329J3L stainless steel exhibits remarkable mechanical properties. It boasts a yield strength of at least 450 N/mm², an ultimate tensile strength of 620 N/mm² or higher, and an elongation rate of at least 18%. This combination of strength and ductility makes it suitable for a wide range of applications.

Heat Treatment

The SUS329J3L stainless steel undergoes a specific heat treatment process to achieve its desired properties. A solid solution treatment at temperatures ranging from 1020°C to 1100°C is followed by rapid cooling to prevent the formation of unwanted phases. This heat treatment ensures the steel's superior corrosion resistance and mechanical properties.

Size Range

JIS G4304 SUS329J3L stainless steel plates and coils are available in a wide range of sizes to meet various application requirements. The thickness of the plates can vary, while the coils can be custom-rolled to specific dimensions.

Impact Testing

To ensure the material's resilience and durability, SUS329J3L stainless steel undergoes rigorous impact testing. These tests simulate real-world conditions to ensure the steel's ability to withstand sudden impacts without failing.

Primary Applications

The SUS329J3L stainless steel finds extensive applications in industries requiring high corrosion resistance and mechanical strength. It is commonly used in chemical processing equipment, offshore oil and gas platforms, power plant equipment, desalination plants, and other specialized chemical environments.
