Machining Nitronic Grades

Posted by Jeff Kirchner on Nov 16, 2017 2:57:00 PM


Based on 1" Dia Annealed (RB 95) 5 hour form tool life using high-speed tools. Carbide tools are suggested, for rates better than 50% of Type 304. These rates are for carbide tools, Type C-2 for roughing, drilling and reaming. Type C-3 for finishing.

Corrosion Resistance

Armco NITRONIC 50 Stainless Steel provides outstanding corrosion resistance - superior to Types 316, 316L, 317 and 317L in many media. For many applications the 1950 F (1066 C) annealed condition provides adequate corrosion resistance and a higher strength level. In very corrosive media or where material is to be used in the as-welded condition, the 2050 F (1121 C) annealed condition should be specified. High-Strength (HS) NITRONIC 50 bars are useful for applications such as shafting and bolting, but do not quite exhibit the corrosion resistance of the annealed conditions in all environments.

Manufacturing highlight: Mechanical property enhancement through the use of grain refinement

Posted by Jeff Kirchner on Feb 10, 2017 2:05:00 PM

Grain refinement

There are many applications that can benefit from grain refinement. Grain refinement is a result of specific manufacturing techniques which allow for a finer grain. In almost every case, a finer grain material will outperform a coarser grain item of the same material. The basis of finer grains being stronger is that while there are more dislocations in the material, it is more difficult to make all these dislocations line up. Finer grains also typically have less precipitates in the boundaries. Precipitates are oxides, carbon, and interstitial elements that are not in solution of the grain. Precipitates are normally not as strong as the material itself - tending to make a precipitated material more brittle.

Super Austenitic Stainless Steels

Posted by Jeff Kirchner on Dec 17, 2012 2:50:00 PM

A stainless is defined as 12% minimum Chromium, which can encompass many stainless grades. There are sub categories of this Austenitic type stainless though. Depending on the composition, some materials are more Austenitic than others; primarily due to their Nickel (Ni), Manganese (Mn), Carbon (C) and Nitrogen (N) contents. To consider this further, you need to understand the corollary to Austenite; Ferrite and Martensite are what many people are looking for when they require magnetism, or magnetic permeability. When you mix Austenite and Ferrite it is a Duplex (contains both, nearly equal amounts). A low Ferrite number generally indicates a lower magnetic permeability. Stainless that is high in Ni, Mn, C, or N or a combination thereof can be an indicator that it will have a lower Ferrite content. Some stainless steels with generous amount of these attain a negative ferrite calculation, using Schaefflers diagram you can predict these on a graph or us a Ferrite Number (FN) formula to arrive at the estimate.
