Is 4130 the same as chromoly?
Chromoly steel is actually alloy steel grade 4130. The alloying elements found in AISI 4130 help to increase the strength to a level higher than that of AISI 1030, which can be increased even more using a proper hardening procedure.
What is 4130 chromoly used for?
Grade Summary: A chromium molybdenum alloy steel. Alloy 4130 is a widely used Aircraft Steel due to its weldability, ease of fabrication and mild harden ability. Alloy 4130 is also vacuum degassed to meet the magnetic particle inspection standards of AMS 2301.
How much does 4130 cost?

How do I know if my BMX frame is chromoly?
A chromoly bike may have a sticker on the seat tube from the tube manufacturer be it Reynolds, Tange or Columbus. Tube shape may also vary on higher end frames (my chromoly HT has a triangle top tube and oval down tube). A Hi-Ten frame will mirror the fashion of when the bike was made.
Is 4130 hard to machine?
Machinability – AISI 4130 steel can be easily machined using conventional methods. However, machining becomes difficult when the hardness of the steel is increased. Forming of AISI 4130 steel can be performed in the annealed condition. Welding of AISI 4130 steel can be performed by all commercial methods.
Is chromoly stronger than Dom?
From the research I have done, chromoly is generally 20-25% lighter than DOM. The reason for this is only because chromoly is stronger so you can use a thinner wall tubing and have the same strength.
Can you mig weld 4130 chromoly?
4130 chrome-moly can be welded with the TIG or MIG process. Preheat is generally not needed for thinner sections (0.120-in), but for tubing larger than 0.120 a 300F-400F preheat is needed to obtain acceptable results.
Is chromoly good for BMX?
Almost any aftermarket part that you upgrade your BMX bike with will be made out of chromoly. This is because chromoly is the ultimate type of metal used in BMX, it will withstand harder riding and has a lower chance of breaking.
Where can I get round chromoly 4130 tubing?
Most of our metal tubing and other products are available through next-day delivery or same-day will-call at one of our California or Arizona locations. Round steel tube 4130 provides good weldability without compromising steel abrasion and impact resistance.
What makes up 4130 alloy steel tubing?
4130 Alloy Steel Tubing is Cold Drawn and Seamless. 4130 alloying elements include Chromium and Molybdenum, and for this reason, it is commonly referred to as Chromoly or Chrome Moly.
What kind of steel is round chromoly tubing made of?
Read more info about 4130 chromoly round tube. Chromoly 4130 is a low alloy steel containing chromium, molybdenum, iron, carbon, and other alloying elements.
How much does it cost to certify a 4130 tube?
Please select an outside diameter. Material certifications are available for 4130 products. There will be a $3.00 per certification charge.
