Home > Stainless Steel Foil
Kyaw Stainless, based in Naypyidaw, Myanmar, is a top distributor of high-quality stainless steel products, including precision stainless steel foil. This extremely thin, flexible sheet metal is produced from high-grade stainless steel, like 304, 316L, and 321, with excellent corrosion resistance and mechanical strength. In rolls, sheets, or custom-cut sizes, stainless steel foil is used extensively in industries that need lightweight yet strong materials. Its resistance to high temperatures and superior formability make it the perfect fit for aerospace, electronics, automotive, medical, and industrial applications involving precision-engineered metal solutions.
Stainless steel foil consists mostly of iron, chromium (16-20%), nickel (8-14%), and, in some grades, molybdenum to provide greater corrosion resistance. It possesses high mechanical strength, 520-750 MPa tensile strength, and good elongation characteristics to provide flexibility during forming processes. Physically, it is 7.9 g/cm³ in density, has a melting point of approximately 1400°C, and possesses superior thermal and electrical conductivity. The ultra-thin nature of the foil allows for precise applications with durability, oxidation resistance, and stability under harsh environmental conditions.

Stainless steel foil finds extensive application in aerospace for thermal insulation and heat shielding, in the automotive sector for catalytic converters and exhaust parts, and in electronics for EMI shielding. It is also critical in medical uses, such as surgical equipment and implants, because of its biocompatibility. In chemical processing, insulation, and industrial packaging, stainless steel foil is used as a heat and corrosion-resistant protective layer. It is also applied in food processing and energy sectors where non-reactive, high-strength materials are needed for long-term performance.

To choose the right stainless steel foil, consider the required grade, thickness, and properties like corrosion resistance, strength, and thermal performance for your application. Match these to industry standards and specific environmental or functional needs.
The pressure rating of stainless steel foil depends on its thickness, grade, and application. Typically, it is not designed to handle high pressures, as it is a thin material mainly used for insulation, shielding, or wrapping.
Yes, stainless steel foil can be used at high temperatures, as it offers excellent heat resistance. Its performance depends on the grade, with some, like 310S or 321, handling temperatures above 1000°C.
Stainless steel foil is delivered with Mill Test Certificates (MTC) according to EN 10204 3.1/3.2, guaranteeing international quality standards. It goes through rigorous testing, such as tensile strength, corrosion resistance, and PMI (Positive Material Identification) tests. It is packaged with moisture-proof wrapping, wooden crates, or specially designed reels to avoid damage during transportation. With effective logistics and prompt delivery, Kyaw Stainless facilitates global supply, serving industries demanding high-quality stainless steel foil for high-precision applications.
