SKD-11 Slitting Blade: A High-Performance Solution for Fiber Reinforced Unidirectional Tape

Slitting is a crucial process in the manufacturing of  CFRT contionous fiber reinforced unidirectional tapes.

The process involves cutting the tape into a desired width and length, which requires high precision and durability of the slitting blade.

slitting blade

SKD-11 is a high-performance tool steel that has been widely used for slitting blades due to its excellent properties such as high hardness, toughness, wear resistance, and corrosion resistance.

This article provides an in-depth look into the SKD-11 slitting blade and its suitability for slitting fiber reinforced unidirectional tapes.

Material Properties of SKD-11

SKD-11 is a cold work tool steel that is composed of high carbon and chromium content, along with other alloying elements such as molybdenum, vanadium, and tungsten.

It is known for its high hardness, toughness, and wear resistance, making it suitable for high-stress applications such as slitting blades.

SKD slitting blade

After quenching, the hardness of SKD-11 can reach above 62HRC, which provides excellent cutting performance and edge retention.

Furthermore, SKD-11 has good corrosion resistance and can withstand high temperatures, making it suitable for use in harsh environments.

Nitriding Treatment of SKD-11

Nitriding is a surface hardening process that improves the wear resistance and fatigue strength of the steel.

SKD-11 can undergo nitriding treatment to increase its surface hardness and extend its service life.

The nitriding treatment time and temperature determine the depth of the nitrided layer and the surface hardness of the part.

For SKD-11 slitting blades, the nitriding treatment time at 525°C can range from 20 to 60 hours, and the nitrided layer depth can range from 0.25mm to 0.35mm, with a surface hardness of 1250HV.

This treatment is ideal for applications where the slitting blade is subjected to high stress and wear, such as slitting fiberglass unidirectional tapes.

The increased surface hardness and wear resistance of the blade can improve the overall slitting efficiency and reduce downtime.

For less demanding applications, such as slitting softer materials, a shorter nitriding treatment time of 2 hours at 570°C can be used.

This treatment produces a nitrided layer depth of 10 to 20μm, with a surface hardness of 950HV.

Suitability of SKD-11 for Slitting Fiber Reinforced Unidirectional Tape

Fiber reinforced unidirectional tapes, especially fiberglass ud tape, can be challenging to slit due to their high strength and abrasive nature. SKD-11 slitting blades are a suitable solution for these materials due to their excellent hardness and wear resistance.

Ud Tape Slitting Machine

The increased surface hardness of the blade after nitriding treatment improves its ability to withstand the high stress and abrasion encountered during the slitting process.

This, in turn, leads to improved cut quality, reduced downtime, and extended blade life.


SKD-11 is a high-performance tool steel that is well-suited for slitting blades due to its excellent hardness, toughness, wear resistance, and corrosion resistance.

The nitriding treatment of SKD-11 further improves its surface hardness and wear resistance, making it an ideal choice for slitting fiber reinforced unidirectional tapes.

By choosing the SKD-11 slitting blade, we  can improve our slitting efficiency, improve lifespan ,reduce downtime, and achieve high-quality cuts on challenging materials.

What is SKD 11 material?

SKD 11 is a type of cold work tool steel, which is a high-carbon and high-chromium alloy steel.

It is commonly used in the manufacturing of tools and dies, such as punches, dies, and press tools, as well as in various other cutting and forming applications.

SKD 11 steel has excellent wear resistance, high toughness, and good machinability.

It can be hardened to a high level of hardness and maintains its dimensional stability during heat treatment.

These properties make it an ideal material for applications where high wear resistance and dimensional stability are required.

In addition to its use in tool and die manufacturing, SKD 11 is also used in various other industries, including automotive, electronics, and precision machinery.

What is the hardness of SKD 11?

The hardness of SKD 11 steel can vary depending on the heat treatment process it undergoes.

Generally, the hardness of SKD 11 ranges from 58-62 HRC (Rockwell C hardness scale) after quenching and tempering.

However, the actual hardness may differ based on the specific application and the desired properties required for the tool or component being manufactured.

What is the difference between SKD11 and high speed steel?

The main difference between SKD11 and high-speed steel (HSS) is their chemical composition and intended use.

SKD11 is a type of cold work tool steel, while high-speed steel is a type of tool steel specifically designed for high-speed cutting and drilling operations.

HSS typically contains tungsten, molybdenum, and cobalt, which provide excellent high-temperature strength and wear resistance.

In terms of chemical composition, SKD11 contains high levels of carbon, chromium, and molybdenum, which provide excellent wear resistance and toughness, making it ideal for use in cutting and forming tools, dies, and molds.

On the other hand, HSS contains more tungsten and less chromium and carbon than SKD11, which gives it higher heat resistance and the ability to maintain its hardness at high temperatures.

Overall, SKD11 is better suited for applications that require toughness, wear resistance, and dimensional stability, while HSS is better suited for applications that require high-speed cutting and drilling operations with high-temperature resistance.

What is UD fibreglass?

UD fiberglass is a type of fiberglass material that consists of continuous fibers arranged in a single direction, also known as unidirectional fiberglass.

These fibers are typically made of glass and are bonded together with a resin to form a composite material.

The unidirectional orientation of the fibers in UD fiberglass provides high strength and stiffness in the direction of the fibers.

This makes it ideal for use in applications that require high strength-to-weight ratio, such as aerospace, automotive, and sporting equipment.

UD fiberglass is commonly used in the manufacturing of structural components, such as beams, rods, and panels.

The properties of UD fiberglass can be customized by choosing the fiber type, resin system, and fiber orientation to meet specific performance requirements.

Overall, UD fiberglass offers a lightweight, high-strength alternative to traditional materials such as metal, wood, and plastic.

Is fiberglass a glass or plastic?

Fiberglass is a composite material that is made up of fine glass fibers and a resin or polymer matrix.

The glass fibers give the material its strength and stiffness, while the resin or polymer matrix holds the fibers in place and provides a protective layer.

So, in essence, fiberglass is neither strictly glass nor plastic.

Rather, it is a combination of the two materials.

The glass fibers in fiberglass provide it with the strength and rigidity of glass, while the resin or polymer matrix provides it with the flexibility and moldability of plastic.

The resulting material is lightweight, strong, and versatile, which makes it useful in a wide range of applications, such as construction, automotive, aerospace, and marine industries.
