  • Best Practices for TIG Welding of 4130 Chrome Moly Tubing

    The 4130 grade of chrome moly is a high strength low alloy (HSLA) steel that contains molybdenum (0.15 0.25 percent by weight) and chromium (0.8 1.1 percent by weight) as strengthening agents. However, it has relatively low carbon content (nominally 0.30 percent), so it welds, machines and bends almost as easily as 1018 DOM mild steel Read More

  • Weldability 1045 & 4140

    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 Read More
