What makes 4130 steel square tubing ideal for structural and aerospace applications?
4130 chrome-molybdenum alloy steel offers an exceptional combination of high strength, excellent weldability, and superior toughness due to its 0.95% chromium and 0.20% molybdenum content. This makes it ideal for aircraft structures, race car frames, bicycle frames, and high-stress structural applications. The square tubing form provides optimal strength-to-weight ratio and uniform load distribution.
What forms of 4130 steel components do you supply?
We supply comprehensive 4130 steel product forms including seamless square and round tubing, bars, reforging stock, sheet, strip, plate, forgings, and rings. All products are available in various heat treatment conditions including normalized, hardened and tempered, or stress relieved to meet specific AMS, MIL, and industry specifications.
What specifications do your 4130 steel products meet?
Our 4130 steel products meet multiple specifications including AMS 6360, AMS 6361, AMS 6362, AMS 6346, AMS 6348, AMS 6350, AMS 6370, MIL-S-6758, MIL-S-18729, MIL-T-6736, DMS 2284, and WS-416. Each specification is tailored for specific applications and forms, ensuring optimal performance in critical environments with various tensile strength requirements from 95 ksi to 150 ksi.
What is the difference between normalized and hardened & tempered 4130 steel?
Normalized 4130 steel is heat-treated to refine grain structure and improve machinability, offering good strength and toughness for general applications. Hardened and tempered 4130 provides significantly higher tensile strength (125-150 ksi) through controlled heating and cooling processes, making it ideal for high-stress aerospace and structural applications requiring maximum strength.
Do you offer custom sizing for 4130 steel square tubing?
Yes, we provide quick response to custom cut and odd size requests with value-added services including precision cutting, machining, and custom heat treatment for 4130 steel materials. Our team can accommodate specific dimensional and tensile strength requirements for your aerospace, structural, or industrial applications.
What industries commonly use your 4130 steel products?
Our 4130 steel products serve aerospace, automotive racing, bicycle manufacturing, oil & gas drilling, structural engineering, and general manufacturing industries. The material's excellent strength-to-weight ratio, weldability, and toughness make it ideal for aircraft landing gear, fuselage structures, race car chassis, drill collars, and high-performance structural applications.
What certifications do your 4130 steel products carry?
All our 4130 steel products come with full material certifications and traceability. Our facility is ISO 9001 and AS 9100 certified, ensuring compliance with aerospace, military, and industrial quality standards. We provide complete documentation including test reports, certificates of conformance, and heat treatment certifications for all aircraft quality materials.
