With the exploration and innovation of company people, gradually formed four major advantageous products: steel plate, steel pipe, stainless steel, special steel.
4130 Alloy Steel Sheet offers good weldability without compromising steel abrasion and is commonly used in structural applications. We carry 4130 in the annealed temper, and the normalized temper. Annealed Steel is "softer" than normalized steel and offers higher workability while normalized steel offers a higher strength tolerance.
Alloy Steel Round Bar 4130 offers good strength and weldability without compromising steel abrasion or impact resistance. This material comes in the normalized condition and doesn't require further heat treatment. It is typically used in structural applications, gears, fasteners, and aircraft exteriors.
Welding 4130 Chrome-Moly. 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.
4130 Steel Sheet & Coil 4130 steel commonly referred to as chromoly is a chrome alloy steel with medium carbon content containing .80 1.10% chromium as the strengthening agent. 4130 coils and sheets is readily machinable has excellent weldability and offers excellent ductility.

What I would suggest is that to best understand the benefits of PWHT on thinwall 4130 is to do some destructive testing of your own. Take some 3" lengths of tube in a size you are interested in and weld up a bunch of T's using a variety of types of welding (gas, TIG, MIG) with a variety of normalizing techniques, then put them in a vice with a big bar on one leg and see how much strain it can buy 4130 weldability
AISI or SAE 4130 grade is a low-alloy steel containing chromium and molybdenum as strengthening agents. The steel has good strength and toughness, weldability and machinability. Type 4130 steel should be forged between 2250 and 1750 F (1230 and 950 C.).

First problem was asking a welding store a question like that. Anyway Per the real welding and engineering handbooks, normally 4130 filler is only used when the entire part will recieve an actual post weld heat treatement. I cant believe they didnt have ER70s-2 or -6 in stock.
Chrome-moly steel offers a good blend of strength, weight and ductility for many motorsports and aerospace applications. The following article discusses some of the recommended procedures and equipment for successfully TIG welding 4130 chrome-moly steel.
2. Weld a little slower than normal. This just makes sense. Think about it. If there is an ongoing argument about GAS welding being superior than TIG welding for Chromoly tubing, then it makes sense to go just a little slower when TIG welding. This will slow the cooling rate and negate any chance of the welded area cooling too fast. 3.
4130 Chrome Moly. Description: Mild Steel Welding Alloy. Formulated to reduce weld metal hot cracking with good ductility. Particularly suited to thin, highly stressed joints. Use S.A.E. 4130 procedure in heat treatment.
You have already received some good advice on welding the 4130 steel. You have already stated that you would not weld it without a WPS, but who is to say the WPS provided by someone is valid unless you see the supporting PQR. I have worked with 4130 on more than one occasion and in both cases the material was stress relieved after being welded.

4130 STEEL SHEETS MIL-S-6345A NORMALIZED Formerly MIL-S-18729C This chromium-molybdenum alloy is one of the most widely used aircraft steels because of its combination of weldability, ease of fabrication and mild hardenability.
Tubing Suppliers in California Tubes are hollow cylinders used for fluid transport, structural applications, or electrical sheathing. They are usually cylindrical in shape, but may have round, rectangular, or square cross-sections.
All 4130 round tubing is made in American/German mills Please select an outside diameter. Material certifications are available for 4130 products. There will be a $3.00 per certification charge.
DOM tubing is welded round steel tube from which the internal weld seam has been removed to create a smooth internal surface. DOM, or Drawn Over Mandrel, tubing generally exhibits precise dimensional accuracy, tight tolerances, and a very smooth, uniform inside and outside finish.
Alloy 4130 is a chrome-moly alloy. It is very popular for welding applications and is often used in the normalized condition without further heat treatment. It can be nitrided to enhance its wear quality. Its popularity is primarily due to its weldability, hardenability, and machinability. Alloy 4130 contains similar properties as Alloy 8630.

TWs cold drawn seamless chromoly 4130 tubing is a lighter weight, higher strength alternative to carbon steel. As the market leader in seamless 4130 tubing, TW Metals delivers a full range of rounds, squares, rectangles, and streamline products. Our tubing is manufactured to Mil-T-6736B, AMS-T-6736, ASTM A519, and AMS 6360 specifications.
However, machining becomes difficult when the hardness of the 4130 steel is increased. Welding; AISI 4130 steel is also good in weldability, and the 4130 alloy may be welded by any commercial method. The material may require a post-weld stress relief heat treatment in certain instances.
The 30 in 4130 represents a value of 0.30 percent carbon content. It is a general cut-off value for weldability. Alloys with more than 0.30 percent carbon are not as easily weldable. A person new to welding will likely say, "I can weld 4140 just as easy as 4130."
4130 Steel Sheet & Coil . 4130 steel commonly referred to as chromoly is a chrome alloy steel with medium carbon content containing .80 1.10% chromium as the strengthening agent. 4130 coils and sheets is readily machinable has excellent weldability and offers excellent ductility.
Hello Victor. Welding 4140HT is not recommended by the manufacturers of this steel and by many who have done it in the field. There are a few things to consider. When you weld on 4140HT you will be annealing the the material near the weld (HAZ), so your end product will not be what the base material is (different microstructure).
For your home built and experimental aircraft needs, the weldability of 4130 Chrome Moly Tubing from Wicks Aircraft is excellent and therefore it finds popular utilization in aircraft type construction where welding is a requirement.

Q: I want to weld on some 7075 aluminum, but I can't find a recommended filler metal for it. Can you tell me the correct filler metal to use? In a word, no. The reason you can't find a recommended filler metal for 7075 is that it is usually considered to be unweldable with arc welding. No one buy 4130 weldability
