This advantage is realized principally where high strength is required in heavy sections. Combining values from the two systems may result in non-conformance with the standard.
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. This standard is not included in any packages. By Stock By Keyword.
Encore Metals –
These bars have no controlled thermal treatment after hot rolling. Red Metals – Bronze, Copper and Brass.
Forged Bar and Plate. Proceed to Checkout Continue Shopping. 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.
Carbon Bar, Plate, Tubing and Structural. Please a443 verify your email before subscribing to alerts. Historical Version s – view previous versions of standard. They respond readily to heat treatment and are comparatively easy to machine in the heat treated condition.
Link to Active This link will always route to the current Active version of the standard. Because of richer alloy content, possesses much deeper hardenability than the series.
Being a resulphurized steel, it machines easily. Portland, OR Phone: In addition, unusually high hardenability insures maximum toughness and ductility at the desired strength level. Alloy Bar and Plate. Your Alert Profile lists the documents that will be monitored. The fatigue-tensile ratio makes atsm grade ideal for highly stressed parts. Their chromium content provides good hardness penetration, and the molybdenum imparts uniformity of hardness and high strength.
It is a widely used medium carbon alloy steel which is relatively inexpensive considering the hardenability it offers. Work Item s – proposed revisions of this standard. Subscription pricing is determined by: It has remarkable non-distorting properties for an alloy steel. The bars are available in the conditions specified in 4. The values stated in each system may not be a4334 equivalents; therefore, each system shall be used independently of the other.
Consequently machinability is inconsistent, as are mechanical properties. It is a relatively high hardenability alloy so that in the heat treated condition it has good overall strength and toughness.

Standards Subsctiption may be the perfect solution. Standards Subscriptions from ANSI provides a money-saving, multi-user solution for accessing standards. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard.
They are asgm carburized, and the well-balanced alloy content permits hardening to produce a strong, tough core and high case hardness. Already Subscribed to this document. As the voice of the U. This abstract is a brief summary of the referenced standard. If the document is revised or amended, you will be notified by email.
They have excellent machinability and respond well to polishing operations. 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.
This refines the as rolled grain structure and gives mechanical properties between the quenched and tempered and the annealed conditions. Combining values from the two systems may result in non-conformance with the standard.
Stainless Steel 316 L ASTM A434/ S43400 Sheets, Thickness: 1-2 mm
This condition should be considered for hot forging applications where further heat treating will be required for finished parts. It is supplied in the heat treated condition to a Brinell hardness of You can download and open this file to your own computer but DRM prevents opening this file on another computer, including a networked server.
The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other.
This material is also available as leaded asym. Hot Rolled Alloy Steels. Click on a category to drill down. This specification covers hot-wrought and cold-finished quenched and tempered alloy steel bars.
ASTM A Standard Specification for Steel Bars, Alloy, Hot Wroug
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. 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.
Please first log in with a verified email before subscribing to alerts. The nickel imparts good toughness and ductility, and the chromium and molybdenum contribute increased hardness penetration and wear. Thus, for high strength in heavy sections, or for highly stressed parts operating under zstm most severe conditions, or where the greatest margin of safety is desired, this is the steel to use.
