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. Pre hardened and tempered 4140 can be further surface hardened by flame or induction hardening and by nitriding. 4140 High Tensile Steel Interlloy Engineering Steels 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 mechanical properties.

Alloy Flat Bar - RyersonAlloy flat bar is available as cold-finished or hot rolled and has excellent hardening capabilities. It responds well to heat treatment and is easy to machine in the annealed condition. Popular applications of 4140 alloy flat bar include blades, brake dies, fixtures and tool holders.
Alloy Steel Round Bar 4140 Cold Finished. 4140 is an oil hardening steel. When heat treated, 4140 exhibits excellent hardenability, abrasion resistance, and fatigue strength. Good machining properties in the annealed condition and somewhat less in the hardened state. When hardened to its most workable hardness of Rockwell 28/32, it exhibits an Datasheet for Steel Grades Carbon Steel ASTM 4140ASTM 4140 Range of products Product type Products Dimension Processes Deliver Status Plates / Sheets Plates / Sheets 0.08-200mm(T)*W*L Forging, hot rolling and cold rolling Annealed, Solution and Aging, Q+T, ACID-WASHED, Shot Blasting Steel Bar Round Bar, Flat Bar, Square Bar 8-1200mm*L Forging, hot rolling and cold rolling, Cast Black, Rough Grade 4140/4142 Steel McMaster-CarrChoose from over 550 grade 4140/4142 steel products in a wide range of sizes.

SAE AISI 4340 Steel (UNS G43400) AISI 4340 steel (UNS G43400) is an ultra-high strength medium carbon low alloy steel, which combines deep hardenability, high ductility, toughness and strength, and has high fatigue resistance and creep resistance. It is not particularly affected by tempering and embrittlement, and exhibits good strength Speedy Metals Information for 4140 Annealed Cold Roll Steel
- ApplicationsMachineability and WeldabilityHeat Treating4140 can be used for as wide variety of applications where greater toughness and wear resistance is needed over lower carbon grades. Typical applications include strippers, holder blocks, mold bases, ejectors, back up and support tooling, fixtures, jigs, molds, cams, drill collars, bolts, stubs, couplings, reamer bodies, axles, shafting, piston rods, rams, hydraulic machinery shafts, gears, sprockets, gear racks, valves, chain links, spindles, tool bodies, tool holders, tie rods, boring bars, guides, tracks, waysSAE/AISI 4140 Round Bar Suppliers, Stockist, Wholesaler SAE / AISI 4140 steel is a low alloy steel containing chromium, molybdenum, and manganese. 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.
