Valmont Tubing produces electric resistance welded (ERW) mechanical steel tubing to meet the SAE 4130 steel grade requirements. Known for its excellent strength to weight ratio, 4130 steel achieves high strength levels without increasing the carbon content and wall thicknesses by the addition of alloying elements Chromium and Molybdenum to its properties. Our ability to produce 4130 electric resistance welded tubing provides our customers with precision tolerances, superior weld quality along with cost & weight savings over other steel grade types and other types of tubing.
The expected content percentages of chemical properties in 4130 steel are listed below:
||0.28 - 0.33
||0.40 - 0.60
||0.15 - 0.35
||0.80 - 1.10
||0.15 - 0.25
The expected mechanical properties for 4130 steel include:
||65,000 - 80,000 psi
||80,000 - 90,000 psi
||10 - 20%
|Rockwell Hardness B
- 4130 steel is sometimes be referred to as chromoly due to the existence of chromium and molybdenum alloying elements.
- End uses of SAE 4130 tubing includes structural, automotive, oil drilling and abrasion resistant applications. Depending upon the application, post weld heat treatment may be required.
