What is a 4-foot x 8-foot 2507 stainless steel plate?
A 4-foot x 8-foot 2507 stainless steel plate refers to a standard-sized plate of super duplex stainless steel 2507 (UNS S32750) with dimensions of 1219 × 2438 millimeters. This size is widely used in industrial manufacturing due to its high material utilization, ease of processing, and excellent compatibility with global cutting and welding equipment. It is specifically designed for marine, chemical, shipbuilding, and pressure vessel applications where standard stainless steel is insufficient.
How does 2507 compare with 2205 stainless steel?
Compared with 2205, 2507 super duplex stainless steel contains higher Cr, Mo, and N, delivering ~25–30% higher pitting resistance (PREN ≥ 40 vs. ~35) and higher yield strength (≥ 550 MPa vs. ≥ 450 MPa).
Is the 4×8 size available in different thicknesses?
Yes, 4×8 (1219 × 2438 mm) 2507 stainless steel plates are typically available in thicknesses ranging from 3 mm to 50 mm, with custom thicknesses supplied for project-specific requirements.
