What is the difference between 4140 and 4145?
As compared to 4140, the 4145 mod grade has higher levels of Chromium and Molybdenum, which will provide much deeper hardening into the steel after austentizing, quenching and tempering. This alloy should not be confused with AISI 4145, as the chemical limits for the modified version are much higher.
What is 4145H?
DESCRIPTION. AISI 4145H is a chromium molybdenum quality alloy steel specification. As a high tensile steel grade AISI 4145H is primarily supplied in the hardened and tempered condition to 30-36HRc range to AISI 4145H modified.

What are the principal alloy elements of an AISI 4340 steel?
AISI 4340 alloy steel is a heat treatable and low alloy steel containing chromium, nickel and molybdenum.
What percentage of carbon is in 4140 steel?
Chemical Composition AISI 4140 is versatile because of its simple chemistry and has the following composition: 0.40 % carbon and 0.85 % manganese which offers toughness and can be heat treated and hardened 0.1 % chromium adds to overall toughness but is not enough to be made into stainless steel.
What is SCM435?
JIS SCM435 Chromium Molybdenum Steel. Categories: Metal; Ferrous Metal; Alloy Steel; AISI 4000 Series Steel; Low Alloy Steel. Material Notes: Forging temp.: 1205°C (2200°F) max.
What is AISI 4340 steel called?
AISI 4340 (E4340) alloy steel is a medium carbon, low alloy steel known for its toughness and strength. Machining is done typically in the annealed condition. 4340 steel properties offer good ductility in the annealed condition, allowing it to be bent or formed.
What is meaning of of AISI 4140?
AISI 4140 is a low alloy steel. Low alloy steels rely on elements other than just iron and carbon to enhance their mechanical properties. In AISI 4140, additions of chromium, molybdenum, and manganese are used to increase the strength and hardenability of the steel.
Is AISI 4140 stainless steel?
AISI 4140 is versatile because of its simple chemistry and has the following composition: 0.40 % carbon and 0.85 % manganese which offers toughness and can be heat treated and hardened 0.1 % chromium adds to overall toughness but is not enough to be made into stainless steel.
What is SAE J403?
J403 is the SAE standard which governs the chemical composition of SAE Carbon Steels, including the grades 1008 and 1010.
What is SCM440?
SCM440 is medium carbon chromium molybdenum alloy steel, which is an alloy steel containing chromium and molybdenum. It has the advantages of stable composition, low harmful elements, high steel purity, small decarburization layer and few surface defects.
Is AISI 4340 Corrosion resistant?
AISI 4340 Steel is highly resistant to atmospheric corrosion because of its combined alloy elements of chromium, molybdenum,nickel and manganese which can not only improve the strength and hardenability of steel, but also improve corrosion resistance.
