ASTM A790 Super Duplex Stainless Steel 2507 Welded Pipe Oxidation Resistance
F53 / S32750 Super Duplex Stainless Steel 2507 Welded pipe 25%Cr Pren ≥40.0
2507 (UNS S32750) 25% chromium duplex stainless steel
National standards:
| ASTM / ASME: A240-UNS S32750 |
| EURONORM: 1.4410-X2 Cr Ni MoN 25.7.4 |
| AFNOR: Z3 CN 25.06 Az |
| DIN / EN 1.4410, ASME SA-240 |
General attributes:
Its impact strength is also very high. The 2507 alloy is not suitable for use at temperatures higher than 570 ° C. If it is exposed to such an environment for a long time, its toughness will decrease. Its chemical composition is shown below
