STAINLESS STEEL STRIPAllegheny Ludlum strip stainless steels are flat-rolledproducts available in coils or cut lengths. Thicknessesrange from .0015" to .1874" and widths range from.1875" to 23.999".

Allegheny Ludlum stainless strip is available withinequipment limitations with any of these edges:

No. 1 - Round or square produced by machining.No. 3 - Produced by slitting.No. 5 - Produced by shaving after slitting.

Specify Allegheny Ludlumwhen you order stainlessand specialty steel strip.

Each strip product is made to your specification. Withproper prints, parts and description of environmentalcondition, the most suitable strip supplied to yourspecification can best be achieved.

Allegheny Ludlum offers fully integrated production ofa complete line of stainless steel strip in all standardgrades and finishes. These are ideal for applicationsrequiring corrosion resistance, strength, durability andease of cleaning.

Our Precision Rolled StripTM products are tailor-madefor specific end uses in the lighter strip thicknesses.These products are typically produced to very tightdimensional, surface, and metallurgical propertytolerances.

Grades 01, 06, A2, A6, A7, D2, S7, H13, M2, M3 and420 ESR are available from inventory.

01 (.9% C, .5% Cr, .5% W, .15% V, 1% Mn) - Generalpurpose, non-deforming oil hardening tool steel forapplications where maximum dimensional accuracy isrequired during hardening. Typical applicationsinclude blanking dies, gages, shims, machine ways,blades, cutters, and cams. (T31501)

06 (1.45% C, 1.25% Si, 1% Mn) - An oil hardeninggrade with a fine dispersion of graphitic carbon forimproved machinability and resistance to galling.Typical applications include gages, punches, formingdies, jigs, and machine parts such as spindles, cams,arbor wear plates, bushings and guides. (T31506)

A2 (1% C, 5% Cr, 1% Mo, .25% V) - An air hardeningcold work grade less expensive than high C - high Crtool steels, with excellent nondeforming properties.For use in dies, rolls, blanking punches, slittingcutters, trimmer dies and gages. (T30102)

A6 (.7% C, 1% Cr, 1.3% Mo, 2% Mn) - An air harden-ing cold work grade with superior nondeformingproperties. Particularly attractive for dies, punches,gages and other tools where close size tolerance isimportant. (T30106)

A7 (2.3% C, 5.25% Cr, 4.75% V, 1.1% Mo, 1.1% W) -An air hardening grade with outstanding abrasionresistance but lower toughness than D2. For use ontooling for maximum production runs. (T30107)

D2 (1.5% C, 12% Cr, 1% Mo, .8% V) - An air harden-ing grade with good nondeforming properties. Widelyused in applications requiring high abrasion resis-tance and high compressive strength, such asblanking, forming and stamping dies, forming andscanning rolls, slitters and gages. (T30402)

S7 (.5% C, 3.25% Cr, 1.4% Mo, .7% Mn) - An airhardening grade with excellent toughness andsuitable for shock resisting service for both hot andcold work tooling applications. Typical uses in blank-ing, forming and perforating dies, shear blades,chisels, plastic molds, punches, hot gripper andheader dies and hot swaging dies. (T41907)

H13 (.37% C, 5% Cr, 1.35% Mo, 1% V, 1% Si) - Anexcellent hot work grade with an outstanding combi-nation of shock resistance, red hardness, and abra-sion resisting properties. Typical applications includedie casting dies, hot forging dies, hot press dies, dieholder blocks, hot work punches and plastic moldingdies. (T20813)

M2 (.84% C, 4.15% Cr, 4.65% Mo, 5.65% W, 1.85%V) - A high speed steel with an excellent combinationof wear resistance, toughness and hot hardness.Suitable for general purpose cutting tool applications,such as boring tools, broaches, chasers, cutters drills,lathe tools, and forming dies. (T11302)

M3 (1.07% C, 4% Cr, 5.1% Mo, 5.5% W, 2.4% V) -Slightly higher wear resistance and lower toughnessthan M2. Typical applications similar to that of M2.(T11313)

420ESR (.35% C, 13% Cr) - This stainless steelgrade is an air or oil hardening mold steel havingsuperior internal cleanliness combined with goodcorrosion resistance. Capable of providing excellentpolished surface quality. (S42000)
