UNS S32205 duplex stainless steel strip is made up of a mixed austenitic and ferritic micro structure.UNS S32205 duplex stainless steel strip, also known as 2205 stainless steel strip. It is also called EN 1.4462 strip.It also comprises of granular structures. It has yield strength of 450N/mm2 and a high tensile strength of 620 MPa and is known to have an excellent resistance to corrosion.
High corrosion resistance: 2205 stainless steel has good corrosion and oxidation resistance in some acidic or alkaline environments because it contains Cr, Mo, Ni and other corrosion-resistant elements.High mechanical strength: Since 2205 stainless steel has a duplex structure, its strength is greater than that of ordinary austenitic stainless steel.Excellent toughness: Generally speaking, 2205 stainless steel has better toughness than 304 and 316 stainless steel, and has higher resistance to crack growth and fatigue strength.High cost-effectiveness: Compared with high-end stainless steel, the price of 2205 stainless steel is relatively low.| Grade | Standard | C | Si | Mn | P | S | Cr | Ni | Mo |
