Mechanical Properties
Mechanical and Physical Properties
2507 Duplex Schedule 20 Stainless Steel Pipe combines high tensile and impact strength with a low coefficient of thermal expansion and high thermal conductivity. These properties are suitable for many structural and mechanical components. The low, ambient, and elevated temperature mechanical properties of 2507 sheet and plate are shown below. All of the test data shown are for samples in the annealed and quenched condition.

2507 Duplex Schedule 20 Stainless Steel Pipe is not recommended for applications which require long exposures to temperatures in excess of 5700F because of the increased risk of a reduction in toughness. The data listed here are typical for wrought products and should not be regarded as a maximum or minimum value unless specifically stated.
