Hot Rolled Alloy Steels

Atsm Alert Profile lists the documents that will be monitored. Tension tests a344 be performed wherein the steel specimens shall conform to the required values of yield s434, tensile strength, and elongation. Parts made with the annealed condition generally require heat treating prior to being placed in service. Please first verify your email before subscribing to alerts.

Hot Rolled Alloy Steels. Forged Bar and Plate. Heating above the critical temperature and cooling in still air produces the normalized structure. In addition, unusually high hardenability insures maximum toughness and ductility at the desired strength level. Because of richer alloy content, possesses much deeper hardenability than the series.

Thus, for high strength in heavy sections, or for highly stressed parts operating under the most severe conditions, or where the greatest margin of safety is desired, this is the steel to use. This material is also available as leaded steel. Red Metals – Bronze, Copper and Brass.

These grades are especially suitable for forging because they have self-scaling characteristics. Link to Active This a4434 will always route to the current Active version of the standard.

Need more than one copy? This abstract is a brief summary of the referenced standard. The nickel imparts good toughness and ductility, and the chromium and molybdenum contribute increased hardness penetration and wear. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard.

It is supplied in the heat treated condition to a Brinell hardness of 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. Standards Subscriptions from ANSI provides a money-saving, multi-user solution for accessing standards. Already Subscribed to this document.

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 standard is not included in any packages. Portland, OR Phone: 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.

ASTM A Standard Specification for Steel Bars, Alloy, Hot Wroug

It is readily machined, easily forged and exhibits good response to heat treating by furnace, flame and induction hardening. Being a resulphurized steel, it machines easily. We have no amendments or corrections for this standard. These bars have no controlled thermal treatment after hot rolling.

They are readily carburized, and the well-balanced alloy content permits hardening to produce a strong, tough core a4344 high case hardness.

This specification covers hot-wrought and cold-finished quenched and tempered alloy steel bars. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Their chromium content provides good hardness penetration, and the molybdenum imparts a4434 of hardness and high strength.

Carbon A344, Plate, Tubing and Structural. This condition should be considered for hot forging applications where further heat treating will be required for finished parts. Standards Subsctiption may be the perfect solution. Work Item s – proposed revisions of this standard.

ASTM A (A29) Grade Composition and Mechanical Properties

Subscription pricing is determined by: 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. They have excellent machinability and respond well to polishing operations. Please first log x434 with a verified email before subscribing to alerts.

The values stated in each system may not be asym equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard. Alloy Bar and Plate. Tool Steel Bar and Plate.

Astn advantage is realized principally where high strength is required in heavy sections. You may delete a document from your Alert Profile at any time. Historical Version s – view previous versions of standard.
