What is the typical lead time for super duplex 2507 fasteners?
For standard fastener sizes from stock material, despatch is within 5 to 10 business days. For non-standard or oversized fasteners requiring forging-grade stock, lead time is 4 to 8 weeks. For mill-direct indent (full mill heat to project specification), lead time is 12 to 18 weeks.
Do you supply NORSOK M-630 and NACE MR0175 certified material?

All super duplex 2507 supplied is qualified to NORSOK M-630 MDS D55 / D57 and NACE MR0175 / ISO 15156-3 as standard, with PREN, ferrite content, Charpy toughness and hardness all reported on the mill test certificate.
