Weldability 1045 & 4140 - American Welding Society

Hi guys, Can anyone comment on weldability of carbon steel AISI 1045 & low alloy steel AISI 4140. Welding staff around me state that weldability of 4140 is better then 1045. Thus, in material selection during design they always go for 4140. They say, the grain size of 1045 is bigger than grain size of 4140 and that is what causing lower

41xx steel - Wikipedia

41xx steel is a family of SAE steel grades, as specified by the Society of Automotive Engineers (SAE). Alloying elements include chromium and molybdenum, and as a result these materials are often informally referred to as chromoly steel (common variant stylings include chrome-moly, cro-moly, CrMo, CRMO, CR-MOLY, and similar).

what is 4140 steel? | BladeForums

However he told me that based on the 41 part of the 4140 name of this steel. that he 'thinks" this steel is a "mild carbon" steel Now this I understand to mean is not the same as 'mild steel"? he says that 4140 does get hard,,,so this tends to make me think that it is not just normal "mild steel" as that stuff is said to not be able to harden
