Five: Overview
The yield strength of 2205 duplex stainless steel is twice that of austenitic stainless steel. This characteristic allows designers to design The weight reduction of the product makes this alloy more price advantageous than 316 and 317L. This alloy is particularly suitable for use in the -50°F/+600°F temperature range. For applications outside this temperature range, this alloy can also be considered, but there are some limitations, especially when used in welded structures.
