Static Crack Resistance of 20 and 30KhMA Steels in a Nace Solution

  • Published:
Materials Science Aims and scope

We study the crack resistance of 20 and 30KhМА steels in a NACE hydrogen-sulfide solution under static and repeated static stresses and found their threshold stress intensity factors. A conclusion is made that these steels almost satisfy the criteria of their applicability in hydrogen-sulfide media accepted in the engineering practice.
