JIS G4304 SUS447J1 hot-rolled stainless steel plate and coil is a high-performance material that is widely used in various industries due to its excellent corrosion resistance and mechanical properties. Manufactured in accordance with the strict Japanese Industrial Standard (JIS), it guarantees superior quality and durability.

Chemical Composition

The SUS447J1 stainless steel boasts a unique chemical composition that contributes to its superior performance. The primary elements include:

 Carbon (C): ≤ 0.01%

 Silicon (Si): ≤ 0.40%

 Manganese (Mn): ≤ 0.40%

 Phosphorus (P): ≤ 0.030%

 Sulphur (S): ≤ 0.020%

 Chromium (Cr): 28.5-32.0%

 Molybdenum (Mo): 1.50-2.50%

 Nickel (Ni) and Copper (Cu) combined: ≤ 0.50%

The high chromium and molybdenum content provides excellent corrosion resistance, while the low carbon and nitrogen levels contribute to improved weldability and reduced sensitization.

Mechanical Properties

The SUS447J1 stainless steel exhibits excellent mechanical properties, including high tensile strength, yield strength, and elongation. These properties ensure that the material can withstand heavy loads and resist deformation under various conditions.

Heat Treatment Status

The hot-rolled process gives the SUS447J1 stainless steel plate and coil a uniform microstructure and improved mechanical properties. The material is typically supplied in the hot-rolled condition, ready for further processing or use.
