Stainless Steel 446 Rectangular Bars are a ferritic stainless steel grade celebrated for their excellent resistance to high-temperature oxidation and corrosion. Typically, their composition features 23–27% chromium, up to 0.2% carbon, along with trace amounts of manganese and silicon. These bars boast impressive mechanical strength and are highly resistant to scaling at elevated temperatures. In terms of mechanics, they showcase a tensile strength of 450–600 MPa, a yield strength of around 200–300 MPa, and a hardness that ranges from 180–220 HB. Their blend of durability and high-temperature resistance makes them perfect for demanding industrial and structural applications.

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.
Stainless Steel 446 Rectangular Bars find extensive use in scenarios that require high corrosion resistance and performance under elevated temperatures. They are frequently utilized in the production of heat exchangers, furnace components, chimneys, boilers, and industrial equipment that face oxidizing environments. Moreover, their strength and stability render them ideal for marine parts, structural supports, and chemical processing equipment. Starc Metals’ stainless steel 446 offerings combine durability, precision, and long-term reliability, making them a trusted choice for industrial, commercial, and construction needs.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
