Nitronic 50 Stainless Steel Supplier

Ram Alloys is a leading supplier of Nitronic 50 stainless steel with stock in a variety of shapes including round bars, square bars, hex bars and mill flats. Nitronic 50 is an XM-19 stainless steel grade that offers superior strength and corrosion resistance compared to the other common austenitic stainless steel variations. At room temperature, grade XM-19 displays double the yield strength of grades 316/316L and 317/317L along with higher levels of oxidation resistance, especially in marine applications.

The standard composition of stainless steel grade XM-19 breaks down as follows:

  • Chromium: 20 to 23 percent
  • Nickel: 11 to 13 percent
  • Manganese: 4 to 6 percent
  • Molybdenum: 1.5 to 3 percent
  • The balance (55 to 63.5 percent) is comprised of iron

Performance Characteristics of Nitronic 50 Stainless Steel

Stainless steel grade XM-19 is widely used in a long list of industries, including oil and gas, petrochemical, pump, marine, chemical processing and transportation, nuclear, and pulp and paper. Its specific performance attributes include:

  • Outstanding tensile & yield strength
  • Elite resistance to corrosion, especially in marine environments
  • Strong mechanical performance properties, particularly at high-temperature elevations & in sub-freezing conditions

Unlike some other stainless steel grades, alloy XM-19 will not become magnetic with prolonged exposure to cold temperatures.

XM-19 High Strength (HS) has been specially processed to enhance specific attributes and performance characteristics. The HS process gives this metal higher strength, a technique that involves dual rolling, annealing and cold working (all of which combine to boost final product durability).                                                                                                                     

This grade is extremely versatile and high performing, given the numerous condition variations seen in these stainless steel alloys.
