Lork Group high-quality AISI 321 (1.4541/X6CrNiTi18-10) is a titanium stabilized austenitic stainless steel with good general corrosion resistance.

Lork Group high-quality AISI 321 (1.4541/X6CrNiTi18-10) is a titanium stabilized austenitic stainless steel with good general corrosion resistance. It has excellent resistance to intergranular corrosion after exposure to temperatures in the chromium carbide precipitation range of 800 – 1500°F (427 – 816°C).

AISI 321 resists oxidation to 1500°F (816°C) and has higher creep and stress rupture properties than alloys 304 and 304L. It also possesses good low temperature toughness.

Stainless steel AISI 321 / 1.4541 is resistant to intercrystalline corrosion, but not to contact with seawater. The material is non-magnetic (amagnetic μr < 1.3) and can be used up to a temperature of 550 °C. In the solution-annealed state (+AT at room temperature), the material has a tensile strength of 500 to 700 N/mm², a hardness of ≤ 215 and a density of 7.9 kg/dm³.

Stainless steel AISI 321 / 1.4541 is extremely easy to weld but only moderately easy to forge. It can be used for cold forming and cold heading. This material is used, for example, in the automotive industry, in mechanical engineering or in the chemical industry.
