1.3964 / UNS S20910 Austenitic Stainless Steel Bar

XM-19 (UNS S20910 / EN 1.3964) Austenitic Stainless Steel Bar is a high-strength nitrogen-alloyed stainless steel offering an excellent combination of strength, corrosion resistance, and toughness. Compared with conventional grades such as 304 and 316, XM-19 provides significantly higher yield and tensile strength while maintaining comparable corrosion resistance. It is non-magnetic in the solution-annealed condition and performs well in marine, chemical, and low-temperature environments. XM-19 stainless steel bars are commonly supplied in round form in accordance with ASTM A276 or A479 standards, with full mill test certificates available.
