With a combination of such highly desirable properties as good strength and wear resistance, excellent toughness coupled with good ductility, and the ability to resist stress at elevated temperatures, it is understandable why these are widely used and highly successful alloy steels.

Tool Steel Bar and Plate. Because of richer alloy content, possesses much deeper hardenability than the series.

The bars are available in the conditions specified in 4. It is a widely used medium carbon alloy steel which is relatively inexpensive considering the hardenability it offers. Carbon Bar, Plate, Tubing and Structural. It is supplied in the heat treated condition to a Brinell hardness of This standard is not included in any packages.


If the document is revised or amended, you a44 be notified by email. This abstract is a brief summary of the referenced standard.


Standards Subsctiption may be the perfect solution. Add to Alert PDF. 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. It is a relatively high hardenability alloy so that in the heat treated condition it has good overall strength and toughness.

The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other.

Standards Subscriptions from ANSI provides a money-saving, multi-user solution for accessing standards. Wstm a resulphurized steel, it machines easily. ASTM does not give any warranty express or implied or make any representation that the contents of this abstract are accurate, complete or up to date.

4142 Heat Treated

Your Alert Profile lists the documents that will be monitored. Combining values from the two systems may result in non-conformance with the standard.

This advantage a4434 realized principally where high strength is required in heavy sections. This material is also available as leaded steel. Click on a category to drill down.

This refines the as rolled grain structure and gives mechanical properties between the ashm and tempered and the annealed conditions. The nickel imparts good toughness and ductility, and the chromium and molybdenum contribute increased hardness penetration and wear. You may delete a document from your Alert Profile at any time.


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.

It is informational only and not an official part of the standard; the full text of the standard itself must be referred to for its use and application.

Link to Active This link will always route to the current Active version of the standard. In addition, unusually high hardenability insures maximum toughness and ductility at the desired strength level.

Please first log in with a verified email before subscribing to alerts. These bars have no controlled thermal treatment after hot rolling. They respond readily to heat treatment and are comparatively easy to machine in the heat treated condition. The steel materials shall be melt x434 by using open-heart, basic oxygen, or electric furnace and shall conform to the austenitic grain size requirement.
