SS 304H angle is a stainless steel product constructed from grade 304H stainless steel, an austenitic alloy with high levels of chromium and nickel. The term "angle" refers to its shape, which resembles a L with perpendicular sides. It is often used for structural support or framing in construction and industrial applications.

The primary difference between the SS 304H and SS 304 angles is their carbon content and consequent attributes. SS 304H has a more incredible carbon content than SS 304, which increases its strength at extreme temperatures. This outstanding carbon content makes SS 304H more suitable for high-temperature applications, such as industrial furnaces or boilers, with improved creep resistance and tensile strength.

SS 304H, also known as Stainless Steel 304H, is an austenitic stainless steel alloy that is primarily composed of iron, chromium, and nickel. It is normally composed of 18% chromium, 8% nickel, and a maximum of 0.08% carbon, distinguishing it from the regular SS 304 grade. Including carbon increases its high-temperature strength and creep resistance, making it appropriate for high-temperature situations.
