What Is SUS304H Stainless Steel Foil?

What is SUS304H stainless steel foil?

SUS304H stainless steel foil is a thin sheet of high-carbon 304 stainless steel, specifically engineered with increased carbon (0.04-0.10%) for enhanced strength, ductility, and creep resistance at high temperatures, making it ideal for demanding applications like boilers, heat exchangers, and petrochemical equipment where heat and pressure are significant factors. The "SUS" prefix denotes stainless steel (often used in Japan), "304" is the base grade, and "H" signifies the high-carbon content for improved high-temperature performance.

 

What standards cover SUS304H stainless steel?

JIS G4305 (foil/sheet standard)

JIS G4313 / JIS G4312 (plate/sheet bar standards for 304H)

 

GNEE supplies 304, 304L, and 304H stainless steel foil with an alloy composition of 18% chromium + 8% nickel. It features resistance to acids and alkalis, high-temperature oxidation resistance, rust resistance, and does not release harmful substances during long-term use. Its service life is more than three times that of ordinary metal foil. Lead-free and cadmium-free, food-grade 304 stainless steel foil is widely used in tableware, kitchenware, and medical packaging. The thickness can be customized from 0.03mm to 0.2mm, with a tensile strength of ≥520MPa. It supports precision stamping and bending processes, meeting the precision processing requirements of electronic shielding covers, sensor components, and other applications.

How do I calculate weight for SUS304H foil?

Weight (kg) = Width (mm) × Thickness (mm) × Length (m) × 7.93 g/cm³ / 1,000,000
(where 7.93 g/cm³ is the density of stainless steel)
