  • Metallographic Etchants for Stainless Steels

    Metallographic Stainless Steel Etchants Etching stainless steels can be somewhat difficult due to the anti corrosive nature of stainless steel. Austenitic or 300 series stainless steels typically have higher chrome as well as a significant amount of nickel (e.g. 304 stainless steel 18% chrome, 8% nickel) which makes them harder to etch.

    The annealed structure in PH stainless steels requires either an aggressive etchant for a short time or a less aggressive etchant for a longer time. Here, Ralph’s reagent could be used for a few seconds, or Vilella’s, which is less aggressive, for a longer time. Vilella’s reagent is

  • Identification of Phases in Stainless Steels by Etching

    Jun 29, 2011 · Identification of Phases in Stainless Steels by Etching. June 29, 2011 by George Vander Voort. Specimens of type 316 austenitic stainless steel that were welded with type 312 weld rod, designed to produce about 12 15% delta ferrite in the weldment, were obtained for the study. The plate was welded from each side using a total of four passes.

  • A general etchant for revealing prior austenite grain

    Abstract. In development of effective etchants for revealing the prior austenite grain boundaries in steels of different composition, microstructure and properties are of significant importance in many areas, for example, in the development of new alloys, in structure property correlations, in steel quality evaluations, and in failure analysis.

  • Stainless Steel Grade 416 (UNS S41600)

    Oct 23, 2001 · 416 is the most machinable grade of stainless steel. It is a low cost grade and can be used unhardened, hardened and highly tempered states. Hardness is optimised at the expense of other properties and corrosion resistance is lower than for austenitic grades. Applications include valves, gears etc.

  • Etching Solution for Stainless Steel?

    Mar 28, 2012 · Etching stainless steel can be difficult but if you thoroughly clean it then get it warm ( about 30 deg C) you gan get a reliable result. I usually use vinyl resist but rapidmask works too. Gotta cut down pressure to 40psi on a pressure pot. Electro etch works well too. I get a deep etch using NaCl ,HCl and a welding inverter.
