is the cloud-based software for NACE MR0175 requirements is the cloud-based software that can help you select materials selection for sour service in accordance with NACE MR0175. NACE MR0175 is an international standard that provides the requirements for metallic materials exposed to H2S in oil and gas production environments. NACE MR0175 is identical to ISO 15156. ANSI / NACE MR0175 / ISO 15156 lists the requirements for carbon steels, low alloys and corrosion resistant alloy exposed to H2S in oil and gas exploration and production environments. is the only cloud-based software that fully incorporates the requirements of NACE MR0175. can be used to evaluate if materials comply to NACE MR0175. The software has a user-friendly interface to enter parameters such as:

  • Temperature
  • Pressure
  • H2S content (%mol or ppm)
  • CO2 content (%mol or ppm)
  • Chloride ionic content
  • Alkalinity uses the input to calculate the following parameters required for materials selection in accordance with NACE MR0175:

  • Partial Pressure of H2S
  • Partial Pressure of CO2
  • pH (acidity)
  • NACE MR0175 severity region
  • Suitability of CRAs including more than 300 alloys

alloyselect is a corrosion software that helps you evaluate the corrosion rates of carbon steel, select corrosion resistant alloys for sour service applications and to verify that materials are compliant with international standards like NACE MR0175, API 6A, API 5CT and many more. is a corrosion software with a difference:

  • No software installation, alloyselect is a corrosion software that is cloud-based, run over chrome, firefox or safari.
  • Compatible with Windows, Max and Linux, alloyselect is a corrosion software that does not need installation.
  • Accessible from mobile and tablet, alloyselect can be accessed from any device with an internet connection.
  • There are no updates to install. There are no installation packages for alloyselect, just subscribe and use.
  • Low cost compared to other corrosion software, alloyselect is a corrosion software with most competitive price.
  • No long term commitments, subscription from just 1 day, immediate access, no emails to send for special codes.


with alloyselect you can use data from reservoir and operation to check if carbon steel is suitable for your asset. alloyselect uses an Artificial Intelligence algorithm to determine sour service severity, corrosion rates and allowance, pH and other threats to the integrity of your asset.


alloyselect uses AI algorithms to identify suitable materials from a library of more than 300 different carbon and low alloy steels, cast irons and corrosion resistant alloys. alloyselect library of codes and standards is continuously updated to comply with regulatory requirements.


alloyselect helps you verify a selected material complies with one or more industry standards. AI algorithms analyse chemical, mechanical and processing data from Material Certificates to verify compliance with code and standards such as NACE MR0175, API 5CT and API6A
