The SS 321 / 321H Pipes & Tubes have titanium stabilization and good all-around corrosion resistance. After being exposed to temperatures in the chromium carbide precipitation range of 800 - 1500°F (427 - 816°C), it exhibits exceptional resistance to intergranular corrosion. The alloy has stronger creep and stress rupture qualities than alloys 304 and 304L and can withstand oxidation up to 1500°F (816°C). It has good low-temperature toughness, as well.

These austenitic-ferritic of SS 321 / 321H Pipes & Tubes that we make are typically utilized in harsh settings. Localized corrosion such as pitting, crevice corrosion, and stress corrosion cracking can be resisted by SS 321 / 321H Pipes & Tubes. Together, austenitic and ferritic chemical compositions produce mechanical qualities that can withstand high-stress conditions. Alpha Overseas manufactures these pipes using pure and high-quality alloys. These SS 321 / 321H Pipes & Tubes are made with titanium, carbon, and nickel content. These components enable SS 321 / 321H Pipes & Tubes to exhibit high corrosion resistance in most conditions. Additionally, it offers great resistance to pitting and crevice corrosion, even in oxidising and acidic conditions.
