Zoom on the 4130 tubes


4130, a 30CrMo4 Chrome Molybdenum steel, is the most popular grade in the United States for the manufacture of alloy steel tubes used in aeronautics and motor racing, particularly for chassis and roll bars. 
Osborn Metals produces these tubes to order according to the AMS T 6736 standard, in the Annealed (A), Stretched Relaxed (N), and Quenched Tempered (HT) states, with three strength levels : HT-125, HT-150, HT -180. 
To respond quickly to requests, a price list has been created for all possible delivery conditions, and a stock of blank tubes has been built up to cover all customer needs.
