工程常见问题
WP304L has lower carbon for improved weld corrosion resistance. Project material specs dictate which grade is required on the line list.
Center-to-end and OD follow the same ASME B16.9 tables for the NPS. Mass is slightly higher for stainless density.
Yes when heat meets both grades. State certification requirements on the inquiry.
Polished or sanitary finish can be quoted for pharmaceutical and food-grade projects.
