4140 steel is an alloyed structural steel known for its high strength, good hardenability, toughness and wear resistance. The chemical composition of this steel mainly includes chromium , manganese , molybdenum and iron and other elements. Its carbon content is usually 0.33% to 0.48%, while the tensile strength can reach 795 mpa and the hardness is about 241HB. Because of its excellent comprehensive mechanical properties, 4140 steel is widely used in many fields, including steam turbine fasteners , fishing tools , machinery manufacturing , automobile manufacturing and aerospace . In addition, 4140 steel also has good wear resistance and durability, making it an ideal material choice for these industries.

AISI 1040 vs 4140 pipe
AISI 1040 and 4040 are both medium carbon iron alloys with 98% iron, and others to offer high strength. Hence. AISI 4140 pipe and tube and AISI 1040 have many similar properties to help construct heat-resistant parts at moderate temperatures. But there are also a few differences between the 4140 alloy steel pipe and the 1040 steel pipe. The following are the differences among others.
- The chromium in 4140 makes it more corrosion-resistant than 1040, which does not have it
- 1040 has a higher Brinell hardness of 201 than 4140, which has 197 MPa
- 4140 has a high tensile strength of 655 than 1040, which has 620
In the Middle East and Africa, pick a trustworthy stockist of 4140 chromoly tubing. check if the AISI 4140 steel pipe is toughened.
Is 4140 Chromoly tubing hardened steel?
Yes. 4140 Chromoly tubing is a hardened steel because of its chromium and molybdenum content to have high hardness and strength. Hence it is best for use in many applications in extreme environments. Also, with oil hardening, it is possible to increase the hardness levels of 4140 tubes.
Because of their hardness, 4140 alloy steel tubes are the best alternative to carbon steel for applications that need strength and fatigue resistance. Also, 4140 alloy has a high tensile and yield strength of 655 and 415 MPa, respectively. The Brinell and Rockwell hardness measurements are also high at 197 and 92, respectively, making them hardened steel.
Find an importer of 4140 alloy steel pipe and tube in Dubai who offers it in a variety of widths and thicknesses. Ask for a price. view the hardness of SAE 4140 seamless tubes
Is 4140 alloy steel seamless pipe harder than stainless steel?
Yes. AISI seamless 4140 pipe is more rigid than stainless steel. It is because of the molybdenum content in 4140, which is not present in stainless steel. But though chromium content in 4140 has good corrosion resistance, it is not like that of stainless steel.
Pipes and tubes made of 4140 alloys have uniform hardness and strength because of molybdenum. Also, with high tensile and yield strength, 4140 is more hardened than stainless steel to be useful in many applications across various sectors. It includes aircraft to automobiles that need high strength, less cost and many other excellent properties.
Locate the most experienced traders of AISI 4140 seamless pipe in the GCC countries, who offer range of standards and sizes. check the rust properties of the AISI 4140 tool steel pipe.
Does 4140 alloy steel pipe rust?
Yes, but AISI 4140 steel pipe rust only under continuous exposure to specific conditions. Also, compared to pipes made of many other types of steel, UNS G41400 welded pipe rusts rarely. It is because of the high iron content of 98% that it can rust if corroded in different conditions. But with molybdenum and chromium, it resists corrosion to a great extent.
AISI has good rust protection because of being made from Chromoly, which has high corrosion resistance. Because of its high torsional, tension and yield strength, it is hard for external forces to damage its surface to avoid corrosion.
Get in touch with reputable distributors to purchase UNS g41400 welded pipe for 10% to 40% less. Also, find out what AISI stands for.
What does AISI stand for?
AISI or American Iron and Steel Institute, started as the steel producers association in 1835 and became SAE, or Society of Automotive Engineers in 1996. It is a prestigious institute to maintain the numbering system for metals and alloys. It helps for easy identification of many steel alloys to make high-quality pipes, tubes, and others.
AISI 4140 tool steel pipe and other pipes and tubes are easily identifiable using the AISI numbering system. The first letter, 4, represents molybdenum, 1 represents chromium and 40 differentiates the steel from others. Hence AISI and its numbers confirm 4140 to be a low steel alloy with high molybdenum and chromium to have excellent properties.
