Stainless Steel 309 / 310 Angles & Flats

Stainless Steel 309 and 310 Angles and Flat are specialized high-temperature alloys renowned for their exceptional heat resistance, oxidation resistance, and mechanical strength. The distinctive chemical compositions of these stainless steel grades confer upon them unique properties, making them invaluable materials for applications demanding sustained operation at elevated temperatures.

Stainless Steel 309 consists of 22-24% chromium and 12-15% nickel, while also containing a low amount of manganese and silicon. This composition imparts remarkable high-temperature strength and resistance to oxidation, making it suitable for furnace components, heat treatment equipment, and other industrial applications. Stainless Steel 310 features a similar composition but includes a higher chromium content (24-26%) and the addition of 0.25% carbon, further enhancing its high-temperature properties.

The standout feature of Stainless Steel 309/310 Angles and Flat lies in their exceptional ability to maintain mechanical strength and resistance to oxidation even at elevated temperatures. They offer superb creep resistance, making them indispensable in applications that involve prolonged exposure to heat and thermal cycling. Their resistance to corrosion and scaling at high temperatures ensures their longevity and reliability in harsh environments.

Heat treatment for these alloys involves annealing to relieve stresses and optimize their high-temperature properties. They are not typically heat treatable for strengthening, as their mechanical attributes are primarily achieved through cold working and solid solution strengthening.

Stainless Steel 309/310 Angles and Flat find crucial applications in the heat processing industry, including furnaces, radiant tubes, and refractory anchors. Their ability to withstand thermal shock and maintain stability at extreme temperatures makes them indispensable for continuous and intermittent heat treatment processes. In the aerospace sector, they are employed in exhaust systems, engine components, and other high-temperature applications. Additionally, these alloys are utilized in various sectors, including power generation, petrochemical processing, and cement production, where their heat resistance and corrosion resilience are of paramount importance.
