What makes 4130 material ideal for buttweld applications?
4130 chrome-molybdenum alloy steel offers exceptional weldability combined with high strength and toughness. Its composition (0.95Cr 0.20Mo with 0.28-0.33C) provides excellent structural integrity for buttweld applications in aerospace tubing, structural components, and high-stress assemblies. The chromium-molybdenum content enhances hardenability and maintains strength at elevated temperatures, making it perfect for critical welded structures.
What forms of 4130 material do you supply?
We supply comprehensive 4130 product forms including bars, sheets, strips, plates, seamless tubing, forgings, and rings. All products are available in various heat treatments including hardened & tempered, normalized, and stress relieved conditions to meet AMS, MIL, and DMS specifications for aerospace and structural applications.
What specifications do your 4130 materials meet?
Our 4130 materials meet multiple AMS specifications (AMS 6346, AMS 6348, AMS 6350, AMS 6360, AMS 6361, AMS 6362, AMS 6370, AMS-S-6758), MIL specifications (MIL-S-6758, MIL-S-18729, MIL-T-6736), and DMS 2284. Each specification is tailored for specific applications and forms with defined tensile strengths ranging from 125 Ksi to 150 Ksi.
What heat treatment options are available for 4130 material?
We offer 4130 material in multiple heat treatment conditions: hardened & tempered for maximum strength (125-150 Ksi tensile), normalized for improved machinability and uniformity, stress relieved for dimensional stability, and various heat treated conditions optimized for specific applications. Each heat treatment is carefully controlled to meet specification requirements.
