CarTech 2205 stainless is a duplex stainless steel that has a microstructure consisting of austenite and ferrite phases. This duplex microstructure and the chemical composition of CarTech 2205 stainless results in an excellent combination of strength and corrosion resistance.

The higher alloyed UNS S32205 provides improved corrosion resistance and meets the requirements of both the S31803 and DIN 1.4462 specifications.

CarTech 2205 stainless possesses good resistance to general corrosion in many acid environments and, has excellent resistance to chloride stress corrosion cracking, pitting and crevice corrosion.

Applications:
CarTech 2205 stainless has been used in high pressure fuel injector systems; oil and gas production equipment such as valves, fittings, shafts, and pump parts; heat exchangers in chemical and pulp and paper plants; and brewery tanks. It can be considered in situations where the strength and or corrosion resistance of Type 316 is inadequate.
