ASTM B677 / ASME SB677 TP904L(UNS N08904)不锈钢和钢管
ASME SB677 TP904L is made of a high-performance austenitic stainless steel alloy called 904L. This alloy is known for its excellent resistance to corrosion, which are typically used in industries such as chemical processing, seawater, oil and gas, and pharmaceuticals. The high-strength pipes are designed without any welds or seams and are produced via the extrusion process. This gives these modules 20% higher load-bearing capacity when compared to the SS 904L Welded Pipe.
