Yunus Sheets and Plates, based in Istanbul, Turkey, is a reputable manufacturer and supplier of high-quality stainless steel products, including Stainless Steel 405 Sheets and Plates. The company prides itself on its commitment to quality, reliability, and customer satisfaction, catering to various industrial sectors that need durable and heat-resistant materials. Stainless Steel 405 is a ferritic stainless steel celebrated for its outstanding oxidation resistance, minimal chromium hardening, and ease of fabrication. Utilizing modern production methods and rigorous quality controls, Yunus Sheets and Plates ensures that their products meet international standards, making them a trusted choice for heat-intensive and structural applications.
Stainless Steel 405 Sheets and Plates are ferritic stainless steels primarily made up of Chromium (11.5–14.5%), with low Carbon (≤0.08%) and small amounts of Aluminum to boost oxidation resistance and minimize hardening. This alloy is known for its good weldability and resistance to thermal fatigue. It boasts a tensile strength of around 415 MPa, yield strength of 205 MPa, and an elongation of 20%. While 405 is not heat-treatable, it offers impressive ductility and toughness in annealed conditions. Its unique composition makes it perfect for applications that require moderate corrosion resistance and high-temperature scaling resistance.
