In the Houston area, service centers like MetalMaster Inc., Texas Alloys, and UltraSteel Houston provide stainless steel 436 angle sections designed for high-temperature and corrosion-resistant uses. These L-shaped profiles generally come in sizes ranging from 20 × 20 mm to 100 × 100 mm, with thicknesses reaching up to 10 mm. You can find them in hot-rolled, cold-rolled, or bright-polished finishes, all adhering to ASTM A240/UNS S43600 standards. Suppliers also offer custom cutting, precision machining, and welding prep, ensuring quick delivery throughout Greater Houston to support industries such as automotive exhaust, industrial furnaces, petrochemicals, and power generation.
Stainless steel 436 (UNS S43600) is a ferritic alloy containing about 16–18 % chromium, 0.75–1.25 % molybdenum, up to 0.12 % carbon, and ≤1 % manganese/silicon, with columbium (niobium) at roughly 5×C (≤0.8 %) to help prevent ridging during forming. In its annealed state, it boasts a tensile strength of at least 531 MPa, yield strength of at least 365 MPa, elongation of at least 22 %, and a hardness of ≤89 Rb (~HB 89). The alloy’s density is around 7.74–7.80 g/cm³, with a modulus of about 200 GPa and a melting point ranging from 1427–1510 °C.

The stainless steel 436 angle provides excellent corrosion resistance, especially in high chloride environments, is ideal for offshore industrial applications and provides excellent resistance to scaling and oxidation at high temperatures. The addition of columbium increases weldability and reduces grain growth, thus prolonging durability. Its high strength and durability make it suitable for construction applications, while its attractive finish complements architectural applications. Corner’s exceptional machinability and form capabilities simplify manufacturing processes, reducing costs. It is also highly resistant to stress corrosion cracking, providing long-term reliability in harsh environments.
These stainless steel 436 angles are perfect for components that need to withstand heat and corrosion. The automotive and aerospace sectors utilize them in exhaust systems, trim, and turbine parts due to their excellent oxidation resistance up to around 760 °C. They’re also found in industrial furnaces, boilers, heat exchangers, and chemical plants, where formability and weldability are essential. Additionally, they’re used in kitchen appliances (like ovens and stovetops), marine structures, power generation equipment, and architectural applications—making the most of their durability and versatility.
