In harsh, corrosive and abrasive environments common to oilfield drilling and exploration, OEM products such as seamless steel tubes, valves and pusher or pipeline connectors are used.
For such extreme operating conditions, case-hardening of carbon steel, ferritic stainless steel, austenitic stainless steel or Inconel is often a design requirement. To that end, nitriding and nitrocarburizing, have been the surface treatment of choice for decades.
