The 300 Series stainless steels are classified as austenitic and are hardenable only by cold working methods. These grades contain chromium (approx. 18% to 30%) and nickel (approx. 6% to 20%) as major alloying additions. They are renowned for resisting corrosion and maintaining strength at high temperatures.
Grade 304/304L: The most versatile and widely used stainless steel. It offers excellent resistance to atmospheric corrosion and many chemicals. The 304L version is preferred for welded applications to eliminate carbide precipitation.
Grade 316/316L: Molybdenum-bearing steel providing superior corrosion resistance compared to 304, especially against pitting and crevice corrosion in chloride environments.
Grade 321/347: Titanium or Columbium stabilized steels designed for excellent resistance to intergranular corrosion after exposure to high temperatures.
Grade 309/310S: High-temperature grades that offer exceptional oxidation resistance and strength at service temperatures up to 1150°C.
