The chemical commonly abbreviated H 2 S. This deadly poison also has a destructive effect on high strength low alloy steels when the hardness of these steels exceeds a hardness of 22 Rockwell C. Indenter : A hardened pointed or rounded contact object used to impress an indentation into the surface of steel or other metal parts in order to obtain a Hardness measurement of that part.
A document published by the National Association of Corrosion Engineers defining the specific limits of chemistry, hardness and microstructure of Materials used to make equipment to contain or control well production fluids that include hydrogen sulfide.
A designation of hardness of metallic materials measured by pressing a small rounded indenter against a clean prepared surface with a specific force. The machine making the indention also measures the depth of the indention and provides a numerical value for that depth. The Rockwell B scale expresses more accuracy in the hardness measurement of metallic materials softer than HRC To convert hardness numbers between measuring methods and scales, see Hardness Number Conversion Chart.
A designation of hardness, usually of steel or Corrosion Resistant Alloys , measured by pressing a specially shaped indenter against a clean prepared surface with a specific force. Some authorities may offer slightly different equivalent hardness numbers. Click here for full Oilfield Glossary. Click for Hardness Number Conversion Chart.
