ASME SB338 UNS R50400 (Grade 2/2H) Titanium delivers exceptional value through three core advantages
(1) Excellent corrosion resistance in chloride environments, including seawater and bleach, surpasses stainless steels by eliminating pitting and crevice corrosion.
(2) Strong strength-to-weight ratio with a tensile strength of 345-400 MPa at only 4.5 g/cm³, enabling lightweight heat exchanger designs that cut structural support costs.
(3) Biocompatible and non-toxic, meeting ASTM F67 medical standards, suitable for both pharmaceutical and marine applications. With over 30 years of titanium manufacturing expertise, YUHONG ensures full traceability from sponge to finished tube, including EN 10204 3.1 certification and custom sizes.
