This condition should be considered for hot forging applications where further heat treating will be required for finished parts. Please first verify your email before subscribing to alerts.
Alloy Bar and Plate. Being a resulphurized steel, it machines easily.
Hot Rolled Alloy Steels On Fay Industries, Inc. (Steel * Saw Cutting)
You may delete a document from your Alert Profile at any time. This abstract is a brief summary of the referenced standard. This standard is also available to be included in Standards Subscriptions. Work Item s – proposed revisions of this standard. Carbon Bar, Plate, Tubing and Structural. This has been the traditional condition for stocking hot rolled flats and squares.
Tension tests shall be performed wherein the steel specimens shall conform to the required values of yield strength, tensile strength, and elongation. Standards Subsctiption may be the perfect solution. The bars are available in the conditions specified in 4. The fatigue-tensile ratio makes this grade ideal for highly stressed parts.
Combining values from the two systems may result in non-conformance with the standard. This standard is not included in any packages. Combining values from the two systems may result in non-conformance with the standard. By Stock By Keyword. Tool Steel Bar and Plate.
4142 Heat Treated
The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. They have excellent machinability and respond well to polishing operations. It is supplied in the heat treated condition to a Brinell hardness of If the document is revised or amended, you will be notified by email.

Hot Rolled Alloy Steels. Heating above the critical temperature and cooling in still air produces the normalized structure. Parts made with the annealed condition generally require heat treating prior to being placed in service.
It is informational only and not an official part of the standard; the full text of the asm itself must be referred to for its use and application. These bars have no controlled thermal treatment after hot rolling. Standards Subscriptions from ANSI provides a money-saving, multi-user aatm for accessing standards.
ASTM A (A29) Grade Composition and Mechanical Properties
It is a widely used medium carbon alloy steel which is relatively inexpensive considering the hardenability it offers. Need more than one copy? Click on a category to drill down.
The values stated in asstm system may not be exact equivalents; therefore, each system shall be used independently of the other. In addition, unusually high hardenability insures maximum toughness and ductility at the desired strength level. Subscription pricing is determined by: You can download and open this file to your own computer but DRM prevents opening this file on another computer, including a networked server.
This grade is quenched and tempered at the mill to a strong, tough yet machinable condition and usually requires no further heat treatment after finish machining unless surface hardened by flame or induction. As the voice of the U. These grades are especially suitable for forging because they have self-scaling characteristics. The steel materials shall be melt processed by using open-heart, basic oxygen, or electric furnace and shall conform to the austenitic grain size requirement.
Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. Portland, OR Phone: We have no amendments or corrections for this standard. Their chromium content provides good hardness penetration, and the molybdenum imparts uniformity of hardness and high strength.

Already Subscribed to this document. Red Metals – Bronze, Copper and Brass. Your Alert Profile lists the documents that will be monitored.
Because of richer alloy content, possesses much deeper hardenability than the series. This material is also available as leaded steel. This refines the as rolled grain structure and gives mechanical properties between the quenched and tempered and the annealed conditions. Consequently machinability is inconsistent, as are mechanical properties.
Because of the fine combination of properties that may be developed, as well as the ease with which it may be processed, this material is ideal for a wide variety of applications.
