Already Subscribed to this document. It is a relatively high hardenability alloy so that in the heat treated condition it has good overall strength and toughness.
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. Their chromium content provides good hardness penetration, and the molybdenum imparts uniformity of hardness and high strength. Add to Alert PDF. This specification covers hot-wrought and cold-finished quenched and tempered alloy steel bars. Red Metals – Bronze, Copper and Brass.
It maintains its strength, ductility, and toughness at relatively high temperatures. Because of richer alloy content, possesses much deeper hardenability than the series.
Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. Forged Bar and Plate. You may delete a document from your Alert Profile at any time. This condition should be considered for hot forging applications where further heat treating will be required for finished aztm. This material is also available as leaded steel.

Carbon Bar, Plate, Tubing and Structural. It has remarkable non-distorting properties for an alloy steel. Alloy Bar and Plate. In addition, unusually high hardenability insures maximum toughness and a34 at the desired strength level.

Need more than one copy? The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. This advantage is realized principally where high strength is required in heavy sections. Your Alert Profile lists astj documents that will be monitored. Combining values from the two systems may result in non-conformance with the standard. Link to Active This link will always route to the current Active version of the standard.
This refines the as rolled grain structure and gives mechanical properties between the quenched and tempered and the annealed conditions.
Historical Version s – view previous versions of standard. They are readily carburized, and the well-balanced alloy content permits hardening to produce a strong, tough core and high case hardness. The fatigue-tensile ratio makes this grade ideal for highly stressed parts. Work Item s – proposed revisions of this standard. It is supplied in the heat treated condition to a Brinell hardness of The values stated in each system may not be exact a44 therefore, each system shall be used independently of the other.
This grade is quenched and tempered at the mill to a strong, tough yet machinable condition and usually requires no further heat treatment a4434 finish machining unless surface hardened by flame or induction. Subscription pricing is determined by: ASTM does not give any warranty express or implied or make any representation aastm the contents of this abstract are accurate, complete or up to date. These grades are especially suitable for forging because they have self-scaling characteristics.
It is readily machined, easily forged and exhibits good response to heat treating by furnace, flame and induction hardening. Proceed to Checkout Continue Shopping. By A4344 By Keyword.

It is a widely used medium carbon alloy steel which is relatively inexpensive considering the hardenability it offers. This abstract is a brief summary of the referenced standard.
