ASTM A358 TP321H Stainless Steel Pipe is a high-alloy welded steel pipe designed for high-temperature and corrosive environments. Grade 1 typically indicates that the steel pipe requires double-sided welding and must undergo comprehensive radiographic or other non-destructive testing to ensure weld quality.
ASME SA358 321H Stainless Steel EFW Pipe incorporates titanium into chromium-nickel stainless steel to prevent intergranular corrosion. This material is suitable for various high-temperature and corrosive environments, maintaining excellent mechanical properties at temperatures up to 870°C. It is particularly ideal for use in applications such as boiler superheaters, heat exchangers, and condensers.
