“…In double tempering process, the samples tempered at 620 o C for 10h have the lowest hardness. The results agree with literature [11,12]. Furthermore, the hardness limit for UNS S41425 steel is 265 HB according to NACE 0175/ISO 15156.…”

“…In this study, the limit was achieved in double tempering process. It can be concluded that double tempering causes considerable effect softening of martensite [12].…”

“…As detailed in Section 2 and Section 3 , the works published clearly show that the change of the strength/hardness of the FZ and HAZ varies between the composition systems and the welding process employed. This is a significant difference from other engineering materials such as carbon or stainless steels, for which, the FZs normally have a hardness increase [ 47 , 48 ]. For nonferrous metals such as magnesium, the hardness for the FZ normally becomes higher but the hardness of the HAZ may drop [ 49 ].…”

“…As the cooling rate decreases in the weld region just after welding, hard and brittle phases like martensite can have less opportunity to form. Authors indicated that if the amount of martensite increases in the weld region, hardness increases but also failures and cracks occur at the same time in their research [15]. 304L stainless steel plates were not heat treated before welding so that these alloys cannot be hardened by transformation of austenite to martensite phases as a result of their low carbon contents [1][2][3][4].…”
