Hot Rolled Alloy Steels

They are readily carburized, a43 the well-balanced alloy content permits hardening to produce a strong, tough core and high case hardness. Because of richer alloy content, possesses much deeper hardenability than the series.

The bars are available in the conditions specified in 4. It has remarkable non-distorting properties for an alloy steel.

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 a relatively high hardenability alloy so that in the heat treated condition it has good overall strength and toughness.

Parts made with a4344 annealed condition generally require heat treating prior to being placed in service. This abstract is a brief summary of the referenced standard. These grades are especially suitable for forging because they have self-scaling characteristics.

ALLOY STEEL ROUNDS – ASTM BOLTING MATERIAL ASTM A193, ASTM A434

Qstm 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. 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.

It maintains its strength, ductility, and toughness at relatively high temperatures. This material is also available as leaded steel.

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. In addition, unusually high hardenability insures maximum toughness and ductility at the desired strength level.

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. As the voice of the U.

This advantage is realized principally where high strength is required in heavy sections. You can download and open this file to your own computer but DRM prevents opening this file on another computer, including a networked server. Work Item s – proposed revisions of this standard. It is readily machined, easily forged and exhibits good response to heat treating by furnace, flame and induction hardening.

The nickel imparts good toughness and ductility, and the chromium and molybdenum contribute increased hardness penetration and wear. 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. 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.
