What is FATIGUE proof steel?
FATIGUE-PROOF is a medium-carbon free-machining steel with higher mechanical properties than its companion product, STRESSPROOF. These properties are produced by a process of drawing steel at elevated temperatures, developed and patented by LaSalle Steel Co.
What is Stressproof steel?
STRESSPROOF is a specialty steel produced by Naigara Lasalle in which a bar is drawn through a die under heavy draft and then stress relieved in a precisely controlled furnace.
How hard is ETD 150?
e.t.d 150 has a150,000 psi (min) tensile strength and a Rockwell C (Rc)Hardness of 32 (min). This eliminates the need for heat treating and secondary operations such as cleaning, straightening and finish grinding.
What is ETD steel?
Alloy ETD 150® is a variation of AISI Alloy 4142 with machining additives and is a registered trademark of Niagara LaSalle Corporation. E.T.D. stands for Elevated Temperature Drawing process. It is drawn at an elevated temperature with a heavy draft to achieve good hardness and strength with a minimum Rockwell ¿C¿ 32.
What is ETD 150 steel used for?
ETD 150® Alloy Steel Round When higher hardness is desired, a level of 57-60 Rockwell C is attainable by quenching and tempering. Along with their high strength, these bars have excellent machining characteristics. Uses include: axles, shafts, gears, pinions, fasteners.
What type of steel is 1144?
medium carbon steel
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.
What kind of steel is 1117?
Grade 1117 steel bar is a low carbon, high manganese, medium sulfur, steel grade that has excellent machinability and is often used for applications needing close tolerances and a smooth surface finish.
Is 1144 a high carbon steel?
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.
What is C1117 steel?
C1117 is a low-carbon, high manganese steel with high mechanical properties and high machinability. 1117 is best suited for machined parts that must subsequently be case carburized. In addition to good surface hardness, the carburized part retains a ductile core.
