XM-19

characteristic:

XM-19 stainless steel has the perfect combination of corrosion resistance and strength not found in any other commercial material. The corrosion resistance of this austenitic stainless steel is better than alloys 316, 316L, 317, and 317L, and the yield strength at room temperature is about twice that of these alloys. In addition, S20910 has excellent mechanical properties at high and low temperatures, which is different from most austenitic stainless steels. XM-19 does not have magnetic properties under low temperature conditions. The yield strength of High Strength (HS) XM-19 is approximately three times that of 316 stainless steel.
