Nitronic® 50
(UNS S20910)

Nitronic® 50 offers an attractive combination of mechanical performance and outstanding corrosion resistance.

Nitronic® 50 is an austenitic stainless steel alloy with outstanding corrosion resistance and superior mechanical performance at both sub-zero and elevated temperatures.

Suitability:

The product is ideal for applications where exposure to high or low temperatures is essential. For example, in the motorsport sector, Nitronic® 50 is a suitable product for racing engine valves.

Excellent Performance:

While the alloy, historically, has been utilised in the oil, gas and petrochemical sectors, motorsport is a recent beneficiary. We stock Nitronic® 50, which serves as yet another example of how Smiths High Performance provides products to give engineers flexible design options. The material grade offers superior corrosion resistance compared to 316 and 317 stainless steel; the alloy is also nitrogen strengthened to provide almost double the yield strength. The end product does not become magnetic when cold-formed, which is unusual for an austenitic alloy. Other favourable performance characteristics include excellent resistance to intergranular attack and SSC (sulphide stress cracking).

Welding:

The alloy is weldable using conventional welding methods, but welding processes can result in a loss of overall strength. While the material offers an attractive combination of strength and corrosion resistance, this is no adverse effect on machinability. The fabrication techniques and machinery used are the same.

Supply Condition:

Nitronic® 50 is typically supplied in the annealed condition for most applications as it offers a superior strength and corrosion resistance combination. A higher-strength option is also available.
