qstm Their chromium content provides good hardness penetration, and the molybdenum imparts uniformity of hardness and high strength. These grades are especially suitable for forging because they have self-scaling characteristics.

They respond readily to heat treatment and are comparatively easy to machine in the heat treated condition. With a combination of such highly desirable properties as good strength and wear resistance, excellent toughness coupled with good ductility, and the astmm to resist stress at elevated temperatures, it is understandable why these are widely used and highly successful alloy steels.
This material is also available as leaded steel.
It is a relatively high hardenability alloy so that in the heat treated condition it has good overall strength and toughness.
Being a resulphurized steel, it machines easily. It is supplied in the heat treated condition to a Brinell hardness of Because of richer alloy content, possesses much deeper hardenability than the series. This advantage is realized principally where high strength is required in heavy sections. In addition, unusually high hardenability insures maximum toughness and ductility at the desired strength level.
ASTM A434/ S43400 Stainless Steel Sheets
The fatigue-tensile ratio makes this grade ideal for highly stressed parts. It maintains its strength, ductility, and toughness at relatively high temperatures.
It has remarkable non-distorting properties for an alloy steel. Thus, for high strength in heavy sections, or for highly stressed parts operating under the axtm severe conditions, or where the greatest margin of safety is desired, this is the axtm to use. The nickel imparts good toughness and ductility, and the chromium and molybdenum contribute increased hardness penetration and wear.
They are readily carburized, and the well-balanced alloy content permits hardening to produce a strong, tough core and high case hardness.
They have excellent machinability and respond well to polishing operations. 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.
