Electron Beam Welding of 42SiCr High-Strength Steel
Welding of high-strength steels is a widely discussed application on a global scale.It is because of the thermally induced processes that take place in the microstructure of the materials being welded.These processes cause mechanical properties of the weld metal and the heat-affected zone to degrade,which may impair the quality of the fabricated structure.The present paper explores the effects of electron beam welding on mechanical properties of an AHS steel.Specimens of high-strength martensitic-austenitic 42SiCr steel have been used.Their ultimate strength was more than 2100 MPa and the A5mm elongation was higher than 15 %.These specimens were welded and then tested in tension.Their microstructure was examined as well.The analysis showed that the material retained high ultimate strength of more than 1780 MPa combined with an elongation level of 6 %.
