AISI 4130 Seamless Pipe is tubing made to the pipe schedule.Alloy pipe in the power industry generally refers to A335 material, but in the
oil and gas market, 4130 Pipe is used. This product is made to the pipe schedule but uses A519-4130 as the controlling Seamless
specification. The material is then heat treated to L80, P110 or the customer’s specified properties. This material is easily welded and is generally used for above ground applications and utilizes the fittings,
flanges and other piping components with the same 4130 chemistry. This product is a good alternative to replace X65 through X80 piping items where the usage or repair is too small for mill production.
AISI 4130 is a low alloy steel containing molybdenum and chromium as strengthening agents. We stocks all AISI 4130 Pipes, 4130 Tubing, 4130 Flanges, 4130 Pipes Fittings, 4130 Elbow etc. The carbon content is nominally 0.30% and with this relatively low carbon content the alloy is excellent from the fusion weldability standpoint. The alloy can be hardened by heat treatment. Typical applications for 4130 low alloy steel include structural use such as aircraft engine mounts and welded tubing applications.
Alloy steels are designated by AISI four-digit numbers. They are more responsive to mechanical and heat treatments than carbon steels. They comprise different types of steels with compositions which exceed the limitations of B, C, Mn, Mo, Ni, Si, Cr, and Va in the carbon steels.

Typical applications for 4130 low alloy steel include. structural use such as aircraft engine mounts and welded tubing applications.
Machinability of AISI 4130
This alloy is readily machined by conventional methods. Machinability is best with the alloy in the normalized and tempered condition. Although the alloy may be machined in the fully heat treated condition, machinability becomes more difficult with increasing strength (hardness) of the alloy.
Forming of AISI 4130
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 of AISI 4130
4130 alloy is noted for its weldability by all of the commercial methods.
Heat Treatment of AISI 4130
Heating at 1600 F followed by an oil quench will harden the 4130 alloy. For best results a normalizing pre-hardening heat treatment may be used at 1650 to 1700 F followed by the 1600 F soak and oil quench.
Forging of AISI 4130
Forge at 2200 F maximum down to 1750 F.
Hot Working of AISI 4130
4130 in the Annealed condition has excellent ductility. Thus it is usually not necessary to do hot working to form parts. If hot working is needed it can be done in the range of 2000 F to 1500 F.
Cold working by conventional methods is readily accomplished on this alloy.
Annealing of AISI 4130
4130 (and most of the other low alloy steels) may be Annealed at 1550 F for a time long enough to allow thorough heating of the section size. It should then be cooled in the furnace at a rate of less than 50 F per hour down to 900 F, followed by air cooling from 900 F.
Aging of AISI 4130
Not applicable to this alloy.
Tempering of AISI 4130
Tempering is done to restore some of the ductility that may be lost after the hardening heat treatment and quench. Alloy 4130 is tempered at between 750 F and 1050 F, depending upon the strength level desired. The lower the tempering temperature the greater the strength.
Hardening is accomplished by heat treatment or by cold working -- see "Heat Treatment".
