1144 Cold Drawn Steel Bar Eaton Steel Bar Company

1144 Cold Drawn Steel Bar. Cold drawn 1144 steel bar is a medium carbon steel that contains high manganese and sulfur. In the cold drawn form, this grade exhibits high tensile properties. Because of the high strength, it can often be used without requiring any heat treatments. :1144 Steel Round Rod, Unpolished (Mill) Finish The 1144 carbon steel grade has medium carbon content for strength, hardness, and resistance to wear, and provides better machinability than 1045 carbon steel. This material can be heat treated for higher hardness. The rod has been cold drawn, a room-temperature process of pulling metal through a die to create the shape.

AISI 1044 Carbon Steel (UNS G10440) - AZoM

Jul 31, 2013 · Carbon steels are a category of steel containing 0.12 to 2% carbon. When the percentage of carbon content increases, hardness and strength of these steels increase with heat treatment, but lose a little amount of their ductility. AISI 1044 carbon steel is medium-carbon steel that can be heat treated, flame or induction hardened. AISI 1144 Steel Stressproof - SAE AISI 1010 1015 1020 1025 1144 steel is actually pretty cool, at least for steel. It is a higher-strength alloy than 1018 or A36 , but in addition has improved ductility as well. The chief feature of 1144 steel, however, is that it has very low distortion or warpage after machining due to a combination of its chemistry, method of AISI O1 Cold Work Tool Steel Data SheetAISI O1 general purpose oil-hardening tool steel is a versatile manganese-chromium-tungsten steel suitable for a wide variety of cold-work applica-tions. Its main characteristics include: Good machinability Good dimensional stability in hardening A good combination of high surface hardness and toughness after hardening and tempering.

All categories Buy Cold Roll Steel Round Bar 1144 Cold Drawn Stressproof Cold Roll Steel Round Bar/Rod 1144 StressProof® is normally used for industrial, machine, and tool applications. 1144 steel has excellent strength and hardness, and is specifically treated to relieve stresses in the metal created during the manufacturing process. This means that the bar is less prone to warping after it is machined or heat treated. 1144 stock is available in full size and custom cut lengths . Carbon Steel AISI 1144 & 1045 Specialty Steel Co.Carbon 1144 is a medium carbon, resulphurized steel with good free-machining qualities and mechanical properties. Its high sulfur content makes this particular grade have a good machinability rating of 83% as compared to 1212 steel; welding though is difficult. AISI 1144

The chief feature of 1144 steel, however, is that it has very low distortion or warpage after machining due to a combination of its chemistry, method of manufacture, and heat treatment. Finally, 1144 is relatively easy to machine, with a machinability rating of 83% of AISI 1212 steel. 1144 Hardness for Sear Surfaces Page 2 The High RoadJul 26, 2020 · AISI 1144 Steel, oil quenched 845°C (1550°F), 540°C (1000°F) temper, 13 mm (0.5 in.) round The suggestion is that it can be used without hardening. Johnm1 , Jul 19, 2020 Heat Treating Steel - Hardening and Tempering The steel is now at its maximum hardness but is very brittle. To reduce the brittleness the metal is tempered by heating it to some where between 350°F and 1350°F. This reduced the hardness a little and the brittelness a lot. Most steels need to be tempered at about 450°F for maximum usable hardness but every steel is slightly different.

Make Sure Your Specified Heat Treatment is Achievable B

quench results in a surface hardness for a 2 in. round would be at J4 and the core would at J8.5. The harden-ability curves show that the corre-sponding surface hardness would be 51-59 HRC with a core hardness of 46-57 HRC. The actual hardness of a given heat of steel would depend strictly on the specific hardenability of that heat.

Also called "stressproof", this alloy has excellent strength and hardness, and is specifically treated to relieve stresses in the metal created during the manufacturing process. This means that the bar is less prone to warping after it is machined or heat treated. Further, 1144 is easily machined. Typically used in nuts, bolts, arbors, gears, pinions, piston rods, sleeves, shafts, and screws.
