The XM-19 is an austenitic stainless steel.Its corrosion resistance and strength are unmatched by commercial materials at the same price.Nitronic50 has better corrosion resistance than 316,316L, 317L, and 317L, and yields up to twice the strength of these grades at room temperature.The yield strength of the high strength Nitronic50 [TJC STEEL](HS) can be up to 3-4 times that of 316 stainless steel.In addition, Nictronic50 has good mechanical properties in both heating and low temperature environments.Unlike most austenitic stainless steels, Nitronic50 does not magnetize when cold worked or cooled to sub-zero temperatures.

Corrosion Resistance of XM-19:

UNS S20910 / XM-19 stainless steel has excellent general corrosion resistance and is superior in many respects to 316/316L and 317/317L.

Annealing conditions at 1950°F (1066°C) provide sufficient corrosion resistance for many applications while providing high [TJC STEEL]strength.When using materials in welded or highly corrosive medium, the annealing condition of 2050°F (1121°C) shall be selected.Materials under high strength cold working conditions are usually used for bolting and shafting connections, but there are some minor compromises in corrosion resistance compared to annealing conditions in some environments.

UNS S20910 / XM-19 stainless steel (annealed) is more resistant to crevice corrosion (e.g., crevice corrosion) than type 316/316L.As [TJC STEEL]with most austenitic stainless steels (such as 304 and 316), XM-19 steel may undergo stress corrosion cracking in an environment containing thermochloride ions.

 

XM - 19 Features:

Xm-19 stainless steel has a perfect combination of corrosion resistance and strength not found in any other commercial material.The corrosion resistance of this austenitic stainless steel is superior to alloys 316, 316L, 317, 317L, and the yield strength at room temperature is approximately twice that of these [TJC STEEL]alloys.In addition, the XM-19 differs from most austenitic stainless steels in its excellent mechanical properties at both high and sub-zero temperatures.

XM-19 also does not become magnetic at low temperatures.

The yield strength of the HIGH strength[TJC STEEL] (HS) XM-19 is approximately 3 times that of 316 stainless steel.

 

XM-19 Application Areas:

Widely used in the Marine, nuclear, chemical and oil and gas industries.
