4140 Alloy Steel Data Sheet - Simply Tool Steel

4140 is an alloy steel that is supplied in either the annealed or prehardened condition. The prehardened condition is heat treated to a medium hardness (HRC 28/32) and is designated as 4140 HT. 4140 annealed is supplied in the soft condition and can be hardened to RC 54. 4140 annealed is designated as 4140 Ann or simply 4140. 4140 HT is supplied in many forms such as hot rolled or turned, ground and 4140 HIGH TENSILE STEEL - Engineering Steels4140 HIGH TENSILE STEEL. 4140 HIGH TENSILE STEEL. 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).4140 is now available with improved. machinability, which greatly increases feeds and/or speeds, while also extending tool life without adversley affecting.

4140 Heat Treated Steel Plate Precision Grinding, Inc.

4140 Annealing & Stress Relieving. With proper furnace heating techniques, AISI 4140 maintains its properties through exposure to the relatively high heating temperatures during annealing or stress relieving. With an on-site 8 x 8 x 14 car-bottom furnace, Precision Grinding anneals parts cut from 4140 every week. We operate the oven every day of the week, M-F, and heat records are stored for every 4140 High Tensile Steel Interlloy Engineering Steels 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).4140 is now available with improved machinability, which greatly increases feeds and/or speeds, while also extending tool life without adversley affecting mechanical properties. 4140 Pre Hard - BICO Steel Service CentersThe machinability of 4140PH is increased by a controlled sulfur addition which gives:500% increase in milling tool life (at constant cutting speed) 300% increase in drilling speed. 30% increase in milling speed.

SAE 4140 steel is a low-alloy steel containing chromium and molybdenum as strengthening agents. These give great corrosion resistance and strength up to around 600°. These characteristics include high strength and good machinability that can easily be heat treated for increased hardness. 4140 Steel Composition 4140 and 4340 alloy steel - Metal and Metallurgy If the heat treat is done correctly for these alloys there will be no retained austenite. In thin sections 4140 would be my go-to grade. Easy to heat treat and a wide range of properties depending on tempering temp. But when you get to thick sections (a few inches) or parts with lots of variation in cross section then the Ni addition shows its

4140-4142 Annealed or Heat Treated? - Material

Sep 25, 2006 · Pre-Hardened 4140-4142 is going to be a bit of a bear to cut with normal cutting tools, (even carbide). But it can be ground with ease, and should be straighter. Teh annealed material will be relatively soft and can be cut easily. You will need to be carefull during heat treat to assure straightness. Alloy Steel Tool Steel 4140 Steel 4142 HT SteelLSS 4140 and 4142HT are versatile, alloy steels that are used in a variety of tooling and other industrial applications. LSS 4140 is the classic AISI 4140 alloy steel that is sold in the annealed condition at a hardness less than or equal to 217 HBW. LSS 4142HT is a similar steel which is sold prehardened to 28 to 32 HRC (269 to 302 HBW). Heat Treating 4140 steel FAQ :anvilfire How-to.1) 4140 is an OK die steel but is not recommended for radical shaped dies such as narrow fullering, crown and so on. 2) Fully hardened 4140 ranges from 54 to 59 HRC. But it should be tempered for any heavy use. 3) Tempering recommendations from the ASM heat treaters guide for 4140-4142 is a minimum of 400°F. This leaves near full hardness.
