ASTM A519 4130 tubing is a Chromoly alloy steel mechanical tubing, delivered in hot finished or cold finished. As a professional 4130 chromoly tubing manufacturer in China, we can offer 4130 seamless alloy tubing and 4130 chromoly tubing with high quality and competitive price.
4130 chromoly tubing has excellent strength-to-weight ratio and are considerably stronger and harder than standard 1026 tubing. 4130 tubing has a relatively low carbon content so it welds and machines almost as easily as 1018 carbon steel tubing. That’s why 4130 tubing is often selected– for it’s blend of ductility, strength, weight and fabrication advantages.
Cold drawn seamless 4130 chromoly tubing has a yield strength of 90k to 100k psi and tensile strength of 110k to 120k psi. It’s high yield strength and high ultimate tensile strength gives you the muscle you need for the toughest jobs.
A519 4130 chromoly tubing strength and resilience has led to their frequent use in high and rise building and bridge construction, as well as most vehicles, many home appliances, tools, pipes, non – illuminated signs and railroad tracks.
ASTM A519 4130/ASME SA 519 4130 mechanical tubing has a high work hardening rate, and efficient machining requires rigid and overpowered machines, sharp tools, preferably carbide – tipped, and heavy, constant feeds. Today, ASTM A519 Tubing with restricted chemistry can be used in the welded condition and is less susceptible to SCC under many conditions.
