4140 Alloy Steel. Alloy steel consists of carbon steel plus elements that increase strength, hardness, and wear resistance. Alloy steel ball stock is commonly used as ball bearings in industrial motion applications. Alloy steel blanks, flats, bars, plates and sheet stock supply solid sheets or bars to be machined into metal parts and products. 4140 High Tensile Steel - Engineering Steels + Alloys4140 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.
Universal Steel stocks 4140 from ¼ thick up to 12 thick, in multiple finished conditions including as-rolled, annealed and pre-hard. 4140 material is low alloy steel, with the presence of chromium, molybdenum, and manganese, which is specifically tailored for applications where strength, hardness, and impact resistance are critical. 4140 Steel Plate Precision Grinding, Inc.Purchased as rolled, Pre-Hardened (PH) or in the annealed condition, 4140 steel plate possesses a full range of hardening and wear resistance properties. Due to its good hardness penetration and uniformity, flame hardening, induction hardening, or oil hardening can increase the wear resistance of 4140 steel.

It is widely used across numerous industries and is an excellent material choice due to its toughness, high fatigue strength, and abrasion and impact resistance. Not many grades can match the versatility and usefulness of 4140. Hot-Rolled Steel vs. Cold-Rolled SteelMar 27, 2020 · The pros and cons of hot-rolled steel come down to strength versus price. Hot-rolled steel is weaker than cold-rolled, but its also cheaper since it doesnt go through the second production process. However, this doesn't automatically mean cold is
Jul 24, 2019 · I 've never turned it on a lathe, but have milled quite a bit of 4140 plate on verticals and horizontal mills.I take .25 to .3 depth of cut at 850 to 900 rpm at 30 to35 ipm with a 2.0 dia iscar.I usually mill/drill at about 65 per cent feed and speed of mild steel.As mentioned earlier, the chips come off easy and it bores like a dream. PRODUCT GUIDES - Central Steel & Wire Co.Product Guide - Steel Plate (contd) Form 1254 3/16/05 (Reprinted 5/27/15) Page 3 of 4 OVERVIEW Cold Reduced Plate Higher in quality (surface, flatness and shape). Maintains flatness after shearing, burning, or laser cutting and lower in cost. Flatness Defect Causes Uneven cooling Non-uniform thickness SAE AISI 4140 Steel Properties, Material Heat Treatment 4140 alloy steel is typically normalized at 870 °C (1600), and should be cooled at a specified temperature in still air. Spheroidizing Annealing For spheroidizing annealing of 4140 alloy steel, it needs heat treated to 749 °C (0 °F), followed by slowly cooling to 666 °C (1230 °F) at a rate of 6 °C (10 °F)/hour, or rapid cooling to 675 °C for isothermal annealing.
Speedy Metals items. 4140 as-rolled plate is a chromium-molybdenun alloy steel that can be oil hardened to relatively high hardenability. The chromium content provides good hardness penetration, and the molybdenum imparts uniformity of hardness and high strength. Steel Sheet & Plate High Quality US Milled SteelHot rolled steel sheet is available as standard hot rolled or as hot rolled P & O. Common hot rolled steel specifications include HR A36, HR A1011, and HR A1018; Hot Rolled Steel Sheet & Plate Advantages Hot rolling utilizes large ingots and large reduction rolling, which not only improves production efficiency, but also creates conditions for Tensile / Yield Strength of Steel Chart - AMESSteel Alloy 1040 - Hot rolled:290 (42) (min) 520 (76) (min) 18 (min) Steel Alloy 1040 - Cold drawn:490 (71) (min) 590 (85) (min) 12 (min) Steel Alloy 1040 - Annealed (@785 °C) 355 (51.3) 520 (75.3) 30.2:Steel Alloy 1040 - Normalized (@900 °C) 375 (54.3) 590 (85) 28.0:Steel Alloy 4140 -
