S32205 Stainless steel pipe
Stainless steel pipe is a kind of hollow long round steel, mainly used in petroleum, chemical, medical, food, light industry, mechanical instrument and other industrial pipeline and mechanical structural parts.In addition, in the bending, torsional strength is the same, the weight is relatively light, so it is also widely used in the manufacture of mechanical parts and engineering structures.It is also commonly used as furniture, kitchenware, etc.

Special specifications can be customized according to customer requirements, please contact us to explain separately!

Resistance to corrosion

Uniform corrosion

Because OF CHROMIUM CONTENT (22%), MOLYBDENUM CONTENT (3%) AND NITROGEN CONTENT (0.18%),2205 HAS BETTER corrosion RESISTANCE THAN 316L and 317L under most conditions.

Local corrosion resistance

The CONTENT OF CHROMIUM, MOLYBDENUM AND NITROGEN IN 2205 DUPLEX STAINLESS STEEL MAKES IT HAVE STRONG RESISTANCE TO PITTING CORROSION AND GAP CORROSION IN OXIDIZING AND ACIDIC SOLUTIONS.

Stress corrosion resistance

The biphasic microstructure of stainless steel is helpful to improve the stress corrosion cracking resistance of stainless steel. Chloride stress corrosion occurs in austenitic stainless steel in the presence of certain temperature, strain, oxygen and chloride. Because these conditions are not easy to control, the use of 304L, 316L, and 317L is limited in this respect.

Corrosion fatigue resistance

The high STRENGTH and corrosion resistance of 2205 duplex steel make it have high corrosion fatigue strength. Processing EQUIPMENT IS SUSCEPTIBLE TO CORROSIVE ENVIRONMENTS and LOADING CYCLES, AND THE CHARACTERISTICS OF 2205 ARE IDEAL FOR SUCH APPLICATIONS.
