When it comes to materials, DIN 2527 PN16 Blind Flanges are typically made from carbon steel (like ASTM A105), stainless steel (such as AISI 304/316), or alloy steel, tailored to meet specific application needs. These flanges boast impressive tensile strength, excellent resistance to corrosion, and good ductility. Their mechanical properties include a tensile strength ranging from 485 to 620 MPa, a yield strength of about 250 MPa, and an elongation of 20% or more. To enhance durability and pressure resistance, they undergo heat treatment, making them perfect for systems that operate under moderate to high pressure and temperature conditions.
