Unlike raw cold-rolled strip, hardened strip delivers consistent mechanical properties across the entire coil: uniform hardness, controlled flatness, and predictable spring-back behavior.
This makes it the material of choice for manufacturers of band saw blades, industrial knives, die cutting rules, doctor blades, springs, and Damascus steel billets. Whether you need a carbon steel strip with high hardness for cutting edges or a spring steel strip with fatigue resistance for flexing applications, the right grade and heat treatment profile is critical.
We supply multiple grades of hardened steel strip, each optimized for specific applications. Select a grade below for detailed specifications.
The global standard for wood band saw blades. Chromium carbides deliver superior wear resistance. Hardness range HRC 47–52. Also used for food cutting bands and general-purpose hardened strip.
Nickel-alloyed spring steel for bimetal band saw blade backing. Exceptional fatigue resistance under cyclic bending. Hardness range HRC 44–52. The standard backing material for metal-cutting bi-metal blades.
Cr-Mo alloy steel with excellent toughness and wide hardenability. Hardness range HRC 28–55. Used for industrial knives, heavy-duty band saw blades, and structural spring applications.
High-nickel steel prized for Damascus pattern welding and premium blade forging. Hardness range HRC 46–62. Nickel content creates the bright contrast layers in Damascus billets.
Japanese carbon tool steel with C 0.85%. Achieves HRC 56–62 after quenching — the highest hardness among carbon grades. Ideal for hardwood band saw blades and scraper blades.
Low-alloy tool steel with excellent impact toughness. Used for large industrial band saw blades and heavy-section cutting tools. Contact us for specifications and availability.
Medium carbon steel with good machinability and moderate hardenability. Suitable for general engineering springs, stamped parts, and components requiring balanced hardness and ductility.
Our heat treated steel strip serves manufacturers across multiple industries. Each application demands specific hardness, flatness, and edge quality.
Wood, metal, and food band saw blades require hardened strip with consistent tooth-tip hardness and fatigue-resistant body. Grades: 75Cr1, SK85, 75Ni8 (bimetal backing).
Slitting knives, shear blades, and packaging cutters need high-hardness strip with excellent edge retention. Grades: 42CrMo4, SK85.
Precision steel rules for corrugated board, label, and gasket die cutting. Tight thickness tolerance and consistent hardness are critical. Grades: 75Cr1, SK85.
Thin hardened strip for ink metering in flexo, gravure, and coating applications. Requires mirror-finish surface and uniform hardness across full width.
Flat springs, constant-force springs, and return springs rely on spring steel strip with controlled yield strength and fatigue life. Grades: 75Ni8, 42CrMo4.
Pattern-welded Damascus billets use alternating layers of 15N20 (bright nickel layer) and high-carbon steel. Our precision strip ensures consistent layer thickness for uniform patterns.
Factory direct with in-house heat treatment lines. All grades from a single source, precision controlled.
