High Performance Alloys, Inc. NITRONIC® HPA N60-PLATE-2.5

通用系列: Steel - Wrought - Stainless - Austenitic提供方: High Performance Alloys, Inc.
High strength fully Austenitic alloy that resists galling and wear. Significantly lower cost to extend part life and lower maintenance. The yield strength is twice that of 304 and 316 stainless steels, in the annealed condition. Tensile strengths can be produced in excess of 200 ksi. Chloride pitting is superior to that of type 316, and the oxidation resistance is similar to type 321 at elevated temperatures, and excellent cryogenic impact strength. Valves stems, seats, and trim; fastening systems, screening, pins, bushings, roller bearings, pump shafts and rings. Food handling, medical, automotive, aerospace and nuclear.

Austenitic Stainless

Nitronic 60 is truly an all purpose metal. This fully austenitic alloy was originally designed as a wear alloy, and subsequently has good high temperature properties for temperatures around 1800 °F. The oxidation resistance of Nitronic 60 is similar to Type 309 S.S., and far superior to Type 304S.S.

The additions of Silicon and Manganese have given this alloy a matrix to inhibit wear, galling, and fretting even in the annealed condition. Higher strengths are attainable through cold working the material and are still fully austenitic after severe cold-working. This working does not enhance the anti-galling properties as is normal for carbon steels and some stainless steels. The benefit to the cold or hot work put into the material is added strength and hardness, and the wear resistance does not decrease noticeably. Chromium and Nickel additions give it comparable corrosion to 304 and 316 stainless steels, while having approximately twice the yield strength. The high mechanical strength in annealed parts permits use of reduced cross sections for weight, and cost reductions through the use of thinner stock.

Several data sheets are available on the wear compatibility of this alloy with dissimilar couples, as well as self-mated coupled results.

If you're galling problem occurs at less than 1500 °F, then you should think about switching to this alloy. Nitronic 60 has a better cost advantage than any other alloy available. Other materials require an additional amount of heat treating to raise their hardness, where Nitronic 60 is excellent in the annealed condition.

Characteristics
Corrosion Properties
Thecorrosion resistance of Armco Nitronic 60 Stainless Steel falls between that of types 304 and 316. However, experience shows that in a wear system, a galling or seizure failure occurs first, followed by dimensional loss due to wear, and finally corrosion. Galling and wear must be the first concerns of the design engineer. Although the general corrosion resistance of Nitronic 60 is not quite as good as Type 316, it does offer better chloride pitting resistance, stress corrosion cracking resistance and crevice corrosion resistance than Type 316 in laboratory conditions. Corrosion tests are not normally performed with Nitronic 60 High Strength.

Corrosion Resistance
Nitronic 60's uniform corrosion resistance is better than 304 stainless in most environments. The yield strength of Nitronic 60 is nearly twice that of 304 and 316 stainless steels. Chloride pitting resistance is superior to that of type 316 stainless; Nitronic 60 provides excellent high temperature oxidation resistance and low temperature impact.
Applications using Nitronic 60 are valve stems, seats, and trim, fastening systems, screening, pins, bushings and roller bearings, pump shafts and rings. Other uses include wear plates, rails guides, and bridge pins.

Applications
  • Automotive valves - can withstand gas temperatures of up to 1500 °F for a minimum of 50000 miles.
  • Fastener galling - capable of frequent assembly and disassembly, allowing more use of the fastener before the threads are torn up, also helps to eliminate corroded or frozen fasteners.
  • Pins - Used in roller prosthetics & chains to ensure a better fit of parts (closer tolerance, non-lubricated) and longer lasting.
  • Marine shafts - better corrosion than types 304 and 316, with double the yield strength.
  • Pin and hanger expansion joints for bridges - better corrosion, galling-resistance, low temperature toughness, & high charpy values at sub-zero temps compared to the A36 and A588 carbon steels commonly used.
