XM-19 1.3964 S20910 Nitronic 50 Hot Rolled Stainless Steel Round
Bar
XM-19, often known by its AK Steel brand name of Nitronic 50, is a
high strength nitrogen-bearing austenitic stainless steel.
It has superior corrosion resistance and strength compared to
316/316L, 1.4404/1.4404 stainless.
Grade
| EN/DIN | AISI/UNS | AK STEEL |
| 1.3964 | XM-19, S20910 | Nitronic 50 |
XM-19 stainless grade combines the following characteristics:
- Better pitting and crevice corrosion resistance than 316/316L and
317L depending on the environment
- Good yield strength (415 MPa minimum) in solution annealed
condition
- Special hot working processes allow yield strength of up to 800 MPa
dependent on section size
- Extremely high strength by cold drawing
- Impact toughness down to cryogenic temperatures. Advantage over
high strength duplex grades
- Use at up to 580°C. Advantage over duplex grades (300°C maximum)
- Non-magnetic even with high levels of cold work
- Difficult to machine due to high hardness
XM-19 stainless offers an excellent combination of high strength
and corrosion resistance.
Its main advantage over competitive materials like duplex grades is
its much wider band of useful temperatures
both at the high and low end of the spectrum. Increased solubility
of nitrogen for high strength is achieved with the
high manganese content.
Its non-magnetic properties are vital in specialist applications
like submarine hulls and minesweepers.
Applications include:
Offshore oil and gas connectors and couplings, chemical storage
vessels, marine drive shafts, pump shafts, valves,
yacht rigging, submarine hulls.
