4130 Chromoly Tubing
Start here for the material itself: what 4130 chromium-molybdenum alloy steel tubing is, how the different trade names relate to the same grade, and what has to be stated on an order.
Product Forms and Shapes
How 4130 tubing is manufactured and in which cross-sections it is realistically available, from cold drawn seamless round tube to the shapes that are not standard in this alloy.
Sizes and Wall Thickness
Outside diameter, wall thickness, weight and dimension references for 4130 tubing, including individual pages for the most requested ODs and walls.
Grades and Equivalents
The same alloy appears under different names in American, European, British and Japanese documents. These pages explain each designation and how far the grades can be treated as equivalent.
Standards and Certification
The specifications that govern 4130 tubing and the documents that prove compliance: ASTM A519, mill test certificates, EN 10204 and inspection options.
Heat Treatment Conditions
The delivery condition changes the strength, ductility and machinability of 4130. Compare annealed, normalized, stress relieved and quenched and tempered tubing.
Applications and Industries
Where 4130 tubing is used and what each industry expects from the material, from roll cages and race chassis to aircraft frames, bicycles, hydraulics and machinery.
Application Suitability Checks
Honest assessments of requests where 4130 mechanical tubing is often asked for but is usually not the right material, with the standards and alloys normally used instead.
