SS 321 angle refers to a structural shape made from stainless steel grade 321, an austenitic stainless steel alloy containing chromium, nickel, and titanium. SS 321 angles are L-shaped structural members commonly used in construction, manufacturing, and engineering applications requiring elevated temperature and corrosion resistance. The addition of titanium in SS 321 provides stabilization against sensitization and intergranular corrosion, making it suitable for use in applications where exposure to high temperatures and corrosive environments is expected. SS 321 angles offer good weldability, formability, and mechanical properties, making them versatile for various structural and architectural designs.

The common types of SS 321 angles typically include equal leg angles and unequal leg angles. Equal leg angles have both legs of the same length and form a 90-degree angle, making them suitable for applications where symmetrical loading or support is required. Unequal leg angles allow one leg to be longer than the other, allowing for versatile positioning and structural configurations. These angles are commonly used in construction, manufacturing, and architectural applications where specific angles and dimensions are needed to accommodate structural requirements and design specifications.

The important grade for SS 321 Angle is ASTM A276. SS 321 Angle is generally produced according to ASTM A276 specifications, which outline the requirements for stainless steel bars and shapes. Within the ASTM A276 standard, SS 321 Angle must meet specific chemical composition, mechanical properties, and dimensional tolerances to ensure its suitability for structural and engineering applications. This specification ensures consistency and quality in the manufacturing of SS 321 Angle, making it a reliable choice for various industries requiring corrosion-resistant and high-temperature structural components.
