What is ETD 150 material?
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.
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.
Is ETD 150 weldable?
ETD 150 is difficult to weld, but can be accomplished by common welding methods as long as the subject section is preheated prior and stress-relieved afterwards.
What is AMS6378?
AMS6378: Steel Bars, 1.0Cr – 0.20Mo – 0.045Se (0.39 – 0.48C) (4142H Modified), Die-Drawn, 130 ksi (896 MPa) Yield Strength, Free Machining – SAE International. Standards.
What is ETD steel?
Elevated Temperature Drawing Steel | Carbon 4100 Alloy Steel E.T.D. 150® stands for Elevated Temperature Drawing process. This eliminates heat treating and secondary operations such as straightening, finish grinding, cleaning and inspections. It can be roll threaded, knurled, and plated.
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 StressProof steel?
To ASTM A311 Class B. 115,000 psi (Min.) 100,000 psi (Min.) 8% Min….FACT: MECHANICAL PROPERTY TESTING.

CAN 1144 steel be heat treated?
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.
Can 8620 be flame hardened?
8620 can be hardened to 1500° F followed by water quench. Carburize at 1650° – 1700° F in an appropriate carburizing medium and oil quench to harden. Tempering of heat treated and water quenched parts (not carburized) is done at 400° – 1300° F, with greater hardness the lower the tempering temperature.
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 does ETD 150 alloy round rods stand for?
EDT 150 Alloy Round Rods ETD 150 stands for Elevated Temperature Drawing process. This eliminates heat treating and secondary operations such as straightening, finish grinding, cleaning and inspections. It is a high strength material that can be roll threaded, knurled, and plated.
What makes an ETD 150 alloy steel bar cold finished?
It is produced by the Elevated Temperature Drawing process patented by the La Salle Steel Co. This process results in a bar that is stress-free and a minimum of 32 Rockwell C hardness, eleminating the need for further heat treating methods. When higher hardness is desired, a level of 57-60 Rockwell C is attainable by quenching and tempering.
Can a castle metals ETD 150 be made commercially?
Customers calling us for ETD 150 a lot of times are struggling with finding commercially available products to meet their specifications. Castle Metals hears these issues often and has resources for thermal and mechanical treatment to deliver customer specific properties.
What does E-T-D stand for in metals?
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.
