This grade is used in the aerospace, oil and gas, and many other industries. This material is often used for shafts, crankshafts, gears, collars, and machinery parts because of its toughness, abrasion and impact resistance, and high fatigue strength. It possesses good machinability in the annealed condition.
What is 4140 steel?
4140 steel is a chromium, molybdenum, manganese low alloy steel plate that is known for its toughness, high fatigue strength, and high torsional strength.
What is 4140 condition t?
4140 is a 1% chromium - molybdenum medium hardenability general purpose high tensile steel - generally supplied hardened and tempered in the tensile range of 850 - 1000 Mpa (condition T). ... Pre hardened and tempered 4140 can be further surface hardened by flame or induction hardening and by nitriding.
What is T condition in steel?
Benefitting from added molybdenum, EN19T not only offers high tensile strength but also high shock and load tolerance characteristics. Supplied in the 'T' condition, the steel's tensile strength performance can be as high as 1000 N/mm².
What does 4140 mean?
molybdenum steel
What type of material is 4140?
alloy steel
Is 4140 hardened steel?
Atlas 4140 is a Chromium-Molybdenum through-hardening steel of medium hardenability. It is a general purpose high-tensile steel with medium strength level and good impact properties.
What tools does 4140 steel make?
A low alloy steel that contains chromium, molybdemum, and manganese, 4140 is typically used to create gears, spindles, fixtures, jigs and many other parts, including: Couplings. Connecting Rods.
How good is 4140 steel?
4140 steel plate has high fatigue strength, excellent toughness, and good corrosion resistance. ... This material is often used for shafts, crankshafts, gears, collars, and machinery parts because of its toughness, abrasion and impact resistance, and high fatigue strength.
Can a hacksaw cut 4140 steel?
Machining Qualities Before 4140 is hardened, it's soft and machine cuts easily. A hacksaw blade will cut it. ... After hardening, it machines fairly well in operations such as sawing, milling or grinding.Apr 24, 2017
Is 4140 considered tool steel?
One of the reasons why 4140 qualifies to be tool steel is the high content of chromium and carbon. The higher the chromium content the better. ... The presence of molybdenum also tends to increase the corrosion resistance of this steel. It also acts as a strengthening agent in this steel alloy.Jun 9, 2020
Is 4140 steel stainless steel?
4140 is a chromium and molybdenum alloy steel that has an excellent weight to strength ratio. ... Although it is chromium steel and often referred to as “chromoly steel” it does not contain as much chromium as stainless steel.
How can you tell if steel is 4140?
RE: Easy Test Needed To Tell 4140 From Carbon Steel The acid test mentioned is: A 1/1 solution of laboratory grade Hydrochloric Acid saturated with Sulfur Dioxide gas. Look for a purple spot. This is actually a test for Moly.Jun 23, 2003
