ASME SA-194 Grade 2HM Heat Treatments


  • This grade shall be uniformly reheated to the proper austenitizing temperature, liquid quenched and then tempered at a temperature not less than 620°C (1150°F) as a final stress relief. After completion of all production heat treatments, heat the specimen nuts to the 540°C (1000°F) for 24 h, then slow cooled.
