Boikanyo Sheets and Plates, located in Cape Town, South Africa, has earned a solid reputation as a reliable manufacturer and supplier of stainless steel 405 angles. Their products are celebrated for outstanding corrosion resistance, durability, and strength. The company specializes in crafting precision-engineered angles that are perfect for structural, architectural, and industrial uses. Thanks to advanced rolling and fabrication techniques, Boikanyo’s 405 stainless steel angles boast consistent dimensional accuracy, a smooth surface finish, and dependable mechanical properties, making them an excellent choice for construction, automotive, and general engineering projects that demand robust yet cost-effective stainless steel solutions.
Stainless steel 405 angles are a type of ferritic stainless steel primarily made of iron, containing 11.5–13% chromium and low carbon levels (≤0.08%). This composition gives them remarkable resistance to oxidation and mild corrosion. With a tensile strength ranging from about 450–550 MPa and a yield strength of 205–350 MPa, they offer good ductility, toughness, and thermal stability. These angles are not only easy to weld and form but also have moderate resistance to scaling at high temperatures, making them suitable for both indoor and outdoor settings where corrosion resistance is essential.
