Semih Metals, located in Istanbul, Turkey, has made a name for itself as a leading manufacturer and supplier of Stainless Steel 446 Rectangular Bars. They specialize in crafting precision-engineered products that cater to the needs of industries around the globe. These bars are celebrated for their impressive resistance to oxidation, corrosion, and scaling, even at high temperatures. Produced using cutting-edge technology and adhering to strict quality standards, Semih Metals guarantees exceptional durability, precise dimensions, and robust mechanical strength, making their offerings incredibly reliable. With a solid foothold in sectors like chemical, petrochemical, power generation, and industrial processing, the company stands out as a trusted provider of top-notch stainless steel solutions for critical applications worldwide.
Stainless Steel 446 Rectangular Bars are primarily made up of iron and chromium, with chromium levels between 23% and 27%, along with trace amounts of carbon, silicon, and manganese. This high chromium content gives them remarkable resistance to oxidation and corrosion, even in harsh environments and at elevated temperatures. In terms of mechanical properties, they exhibit moderate tensile strength, excellent creep resistance, and dependable toughness, although they can’t be hardened through heat treatment. Their ability to maintain structural integrity under thermal stress makes them ideal for challenging conditions that involve high temperatures and corrosive elements.

When selecting Stainless Steel 446 Rectangular Bars, consider factors like temperature resistance, corrosion resistance, and the specific environmental conditions. Additionally, ensure compatibility with the required mechanical properties and fabrication needs.
Stainless Steel 446 Rectangular Bars are not ideal for cryogenic applications due to their reduced toughness at low temperatures. For cryogenic use, materials with better low-temperature properties, like austenitic stainless steels, are recommended.
Stainless Steel 446 Rectangular Bars generally do not require additional corrosion protection coatings due to their inherent high corrosion resistance. However, in highly aggressive environments, coatings may be used for added protection.
These Stainless Steel 446 Rectangular Bars are widely utilized in industries that require outstanding heat and corrosion resistance. You’ll find them in furnace components, petrochemical equipment, kiln linings, heat exchangers, and power generation systems. Their ability to withstand hot gases and corrosive chemicals makes them essential in chemical processing facilities and metallurgical applications. Moreover, these bars are also used in cement plants, incinerators, and other sectors that need durable structural materials. Their long-lasting performance ensures reliability in demanding environments, supporting safe and consistent industrial operations.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
