Annealed and normalized mechanical properties and chemical properties of 4130 and 4140 grade steel included. The following is a comparison of 4130 grade steel and 4140 grade steel. This information may be useful for machining purposes and as a resource for purchasing 4130 and 4140 steel.
With the largest stocked inventory of aircraft quality steel, Benedict-Miller delivers the best chromoly 4130 (E4130) alloy steel sheet, plate, or round bar cut and finished to your specifications when you need it.
Formability is best in the annealed condition for which the ductility is very good, Bend radii of 1t on annealed sheet material may be made. Welding 4130 alloy is noted for its weldability by all of the commercial methods. Heat Treatment Heating at 1600 F followed by an oil quench will harden the 4130 alloy.
The 4130 alloy steel sheet has been annealed, has an unpolished (mill) surface, meets SAE Aerospace Material Specifications AMS 6350 standards, and has a standard tolerance. The 4130 alloy steel grade contains chromium and molybdenum for strength and hardenability, with lower carbon content than 4140 alloy steel to provide better weldability.
Why are they using annealed 4130? You can get steel DOM stronger than annealed 4130 tube. I would only use annealed for ease of fabrication before being heat treated and tempered to restore strength and toughness. Normalized 4130 is best to use for fabrication because it's workable, weldable, and still strong without post fab heat treatment.

AISI 4130 Steel | 25CrMo4 | 1.7218 | 708A25 | SCM430. AISI 4130 alloy steel is a medium carbon, low alloy steel in ASTM A29 standard. ASTM 4140 steel is also commonly referred to as a chromoly steel, or chrome moly steel, containing nominally 0.28-0.33% Carbon, 0.8-1.1% Chromium and 0.15-0.25% Molybdenum.
Alloy Steel 4130 (Chromoly) Steel Plate. Standard mill sizes for Alloy Steel 4130 Steel Plate range from 0.025 all the way up to 4. Other sizes may be available. Contact your local Metal Supermarkets store to confirm availability and pricing. Please note all items are subject to availability.
Annealed SAE-AISI 4130 is SAE-AISI 4130 steel in the annealed condition. It has the lowest strength compared to the other variants of SAE-AISI 4130 steel. The graph bars on the material properties cards below compare annealed SAE-AISI 4130 to: SAE-AISI wrought steels (top), all iron alloys (middle), and the entire database (bottom).

Welding 4140 to stainless. Since hastelloy W has become so expensive, 309 stainless filler was used to weld the 4130 to 303. welding free machining 303 stainless is not even recommended for some applications but this particular part was more like an alignment gauge and was never going to be loaded at all.
4130 Normalized vs. Annealed Sheet - Zach Guzman 4130, also known as Chrome Moly (aka Chromoly) (so named for 2 key elements of its composition, chromium, and molybdenum), is a general-purpose alloy steel that has been widely used by the aviation and motorsports industries for years.
AISI 4130 steel can be annealed at 843C (1550F) followed by air cooling at 482C (900F). Tempering of AISI 4130 steel can be performed at 399 to 566C (750 to 1050F), depending on the desired strength level. Hardening of AISI 4130 steel can be done with cold working or heat treatment. Some of the major applications of AISI 4130 alloy steel are in aircraft engine mounts and welded tubing.
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.).
Formability is best in the annealed condition for which the ductility is very good, Bend radii of 1t on annealed sheet material may be made. Welding. 4130 alloy is noted for its weldability by all of the commercial methods. Heat Treatment. Heating at 1600 F followed by an oil quench will harden the 4130 alloy.
4130 Product Guide Applications | Specifications | Mechanical and Chemical Data Overview. Offers good strength, and weldability without compromising steel abrasion and impact resistance. Easy to machine and hot work as well as cold work in the annealed state, it becomes significantly more challenging once the steel is hardened. 4130 steel can also be easily welded.
My curiosity got the best of me because I had remembered that you could temper at higher temperatures with reduced time to achieve similar hardness results because tempering is a thermal activation process (time and temperature dependent). I was able to locate a H-J tempering parameter plot for AISI Type 4130 Q&T.
4130 annealed acts pretty darn close to A36 or 1018, maybe back it down 10 or 15%. A bit gummy, but pretty easy to deal with, just pile it on, hard and fast. Milling 300sfm on the very low end, up to maybe 600sfm with solids, up to 1000 or so with indexables. 1400sfm isn't out of the question on a finish pass with an indexable.

Introduction. AISI 4130 steel (UNS G41300), also known as 4130 Chromoly steel, is a chrome-molybdenum series low alloy steel with high strength, toughness and hardenability, usually used in quenched and tempered condition.
Well there is a slight difference. 4130 is 30% carbon. If you heat treat it with 4140 which is 40% carbon, it will slightly carburize the 4140. It will not be that much of an issue at all but there is actually a difference.
