4130 (AMS6346)

Our 4130 chromium-molybdenum steel bars offer moderate tensile strength.

---

4130 alloy is a chromium-molybdenum steel bar product that finds extensive use in aerospace. The product offers various attractive performance characteristics, including ease of fabrication, good weldability and mild hardenability. The alloy has sufficient strength for a broad range of commercial applications in the normalised delivery condition.

Harder & Stronger

4130 is considered harder and stronger than most standard carbon steels and offers an excellent strength-to-weight ratio. High oxidation resistance is another impressive feature, and the alloy also responds well to nitriding, which results in good abrasion and wear resistance. Although overall weldability is good, pre and post-weld heat treatment is required to avoid cold cracking. Applications include aerospace and automotive components and use in general engineering.

Processing

We offer comprehensive billeting services using a range of processing equipment. Bars are cut to tight tolerances to match our client's needs, and in many cases, this added value service negates the need for any additional cutting, which saves you money.

Stock Availability

We have available 4130 steel bars in a wide range of sizes and condition (including normalised, hardened, quenched and tempered conditions).
