Key Features of Alloy Steel AISI 4130 (Chromoly)
Excellent Weldability
AISI 4130 contains lower carbon (0.28-0.33%) than 4140, offering significantly better weldability. It is widely used in welded structures like aircraft frames and roll cages without requiring extensive pre/post heat treatment.
High Strength-to-Weight Ratio
Provides high tensile strength and ductility, making it ideal for applications where weight saving is critical but strength cannot be compromised.
Through-Hardening Ability
Contains Chromium and Molybdenum which provide good deep hardenability. It responds well to nitriding for improved surface hardness and wear resistance.
Good Machinability
In the annealed or normalized condition, AISI 4130 offers good machinability. It is easily machined using conventional methods, making it versatile for fabricating complex parts.

AISI 4130 Bars FAQ
AISI 4130 has a lower carbon content (0.28-0.33%) compared to AISI 4140 (0.38-0.43%). This makes 4130 significantly easier to weld and fabricate, while still offering good strength. It is often preferred for structural applications like aircraft frames and roll cages.
Yes, AISI 4130 has excellent weldability compared to other alloy steels. It can be welded using all commercial methods, and unlike 4140, it often does not require pre-heating or post-weld heat treatment for thinner sections.
We supply AISI 4130 bars in Hot Rolled, Cold Drawn, Annealed, Normalized, and Quenched & Tempered (Q&T) conditions, depending on the required mechanical properties and machining needs.
