Physical property

Density :7.69g/cm3

Melting point :1385-1443℃

Features:

The yield strength of 2205 duplex stainless steel is twice that of austenitic stainless steel, which allows designers to reduce weight when designing products, making this material less than 316 and 317L

More price advantage. 2205 resists stress corrosion cracking better than 304 and 316L, and also resists spot corrosion and crevice corrosion caused by chloride. This kind of biphase rust proof

Steel is particularly suitable for environments where chlorides and hydrogen sulphide are present such as Marine applications and oil and gas production.

Applications:

Oil and gas pipelines, pipe parts, heat exchangers, pulp and paper industry bleaching equipment, storage and treatment systems, tank ships, car storage tanks, chemical industry pressure vessels, storage

Storage tank, high pressure pipeline, heat exchanger, food processing equipment.
