Table Of Content
The manufacturing process of AISI 4140 Round bars starts by using the fine quality of the premium quality of raw substances that is collected from reliable mills. The alloy we are using is very well tested by the quality checker team and is approved for use in the development of bars. AISI 4140 is the 1% chromium and molybdenum is a general-purpose medium harden-ability and high tensile strength steel alloy. The alloy is generally provided to the buyers in tempered and in hardened conditions in the tensile ranges of about 850 to 1000 MPA. This alloy is now available with well-improved machinability that is greatly increasing speed or feed along with the extending tool with affecting badly the mechanical properties.
The use of refined technology and modern tools has helped us in the development of the fine quality of round bars as per the needs of tough applications. There at our manufacturing unit, the development of whole ranges of these round bars is done under the tight supervision of professional experts. They are using their skills for the development of high quality of bars as per the expectations of the clients.

very good features to offer and therefore it is thus used in
ranges of industrial applications. The properties found in it
are like-
• Non-corrosive body
• Pitting and oxidation resistance
• Stress corrosion cracking and crevice corrosion resistance
• High hardness
• Good dimensional accuracy
• Fine surface finishes
• Good mechanical strength
• High tensile strength
• Long service functional life
• Flexible to use
Testing of the bars-
The testing of
the AISI 4140 Round bars is done at our manufacturing unit
before the dispatching of it to the buyers. The testing is
done mainly for checking the quality of the bars. Quality
testing that we conduct is positive material identification
test, pitting resistance test, macro test, micro test,
hardness test, intergranular corrosion test, chemical test,
mechanical test, flare test and flattening test.
Test certifications and product documentations-
We are the responsible dealer and are thus offering some
important testing certifications and product documents to the
buyers. The reasons why we are providing it to the buyers are
just to make them sure about the product quality. The test
