Product Details:

Alloys 309 and 309S are austenitic chromium-nickel stainless steels that are often used for higher temperature applications. Due to their high chromium and nickel content, Alloys 309 and 309S are highly corrosion resistant, have outstanding resistance to oxidation, and excellent heat resistance while providing good strength at room and elevated temperatures. The only significant difference between 309 and 309S is the carbon content. Alloy 309S has a much less carbon composition which minimizes carbide precipitation and improves weldability.

Applications:

• Alloys 309 and 309S are used exclusively for their high temperature oxidation resistance, excellent high temperature strength, along with their resistance to creep deformation and environmental attack. 

Some examples include, but are not limited to: 

Heating elements:

• Aircraft and jet engine parts
• Heat exchangers
• Carburizing annealing products
• Sulfite handling equipment
• Kiln liners
• Boiler baffles
• Refinery and chemical processing equipment
• Auto exhaust parts

Standards:

• UNS S30900/S30908
• ASTM/ASME: UNS S30900/S30908
• EURONORM: FeMi35Cr20Cu4Mo2
• DIN: 2.4660

Product Details:

The term nitronic® refers to the way in which nitrogen has been used to stabilise and strengthen the alloy. Unlike other kinds of nitrogen-enhanced steel, nitronic® is notable as the nitrogen has been added internally, rather than being nitrided to the surface of the alloy

NIMONIC® alloy 80A (UNS N07080/W. Nr. 2.4952 & 2.4631) is a wrought, age-hardenable nickel-chromium alloy, strengthened by additions of titanium, aluminum and carbon, developed for service at temperatures up to 815°C (1500°F). It is produced by high-frequency melting and casting in air for forms to be extruded.

Ferralium 255 is a super duplex stainless steel in the Ferralium family. It was the first super duplex stainless steel. Developed by Langley Alloys to meet the needs of the oil, gas and chemical industries, Ferralium 255 achieves higher strengths than most other stainless steel varieties and corrosion-resistant alloys
