  • Stainless Steels Welding Guide Lincoln Electric

    STAINLESS STEELS Austenitic stainless steels include the 200 and 300 series of which type 304 is the most common. The primary alloying additions are chromium and nickel. Ferritic stainless steels are non hardenable Fe Cr alloys. Types 405, 409, 430, 422 and 446 are representative of this group. Martensitic stainless steels are similar in Read More

  • Effect of hydrogen on ductility of high strength 3NiCrMo

    An increase of the Mo content from 0.43% to 1.06% has been tried so as to increase the strength level of the 3NiCrMoV martensitic steels from 1300 MPa to 1500 MPa. Hydrogen embrittlement susceptibility of the two steels after quenching and 575 °C tempering has been evaluated by means of slow strain rate tests.Read More
