Materials

Reliability without wear and tear
When it comes to tools, such as wrenches and pipe pliers, for example, which need to withstand high loads, properties such as high tensile strength, the corresponding ductility of the material with higher elasticity and the lowest possible susceptibility to cracking are of particular importance. These requirements are particularly well met by Premium chrome/vanadium steel, an alloyed tool steel with manganese, chrome, silicon and carbon. Tools made from this steel have a long service life and are an excellent choice for many years of use.

Alloyed tool steel 31CrV3, in accordance with EU directive 2000/53/EC

• 0.60% manganese for higher tensile strength and ductility
• 0.60% chrome for lower susceptibility to cracking and higher tensile strength
• 0.30% silicium for higher elasticity
• 0.35% carbon for appropriate tool hardness

Wrenches and pipe wrenches made of chrome/vanadium steel with added alloyed elements for even better properties have a particular ergonomic shape, are safe to use and are now also characterised by even higher resistance to wear.

Excellence that can withstand high torque
A lower susceptibility to cracking is particularly important for tools such as socket wrenches. Tool steel with a higher chrome and manganese content guarantees a higher tensile strength. An appropriate carbon content simultaneously ensures the corresponding hardness of the tool. Premium Flex chrome vanadium steel, an alloyed tool steel with manganese, chrome and carbon, allows for the redesign of tools that can withstand high torques.

Alloyed tool steel 25CrMo4, in accordance with EU directive 2000/53/EC

• 0.75% manganese for higher tensile strength and ductility
• 1,00% chrome for lower susceptibility to cracking and higher tensile strength
• 0.35% carbon for appropriate tool hardness

Tools made from high-quality chrome vanadium steel with a higher content of selected alloyed elements can now be even better adapted to specific uses, due to their suitability for high torques and their corresponding strength.

Durability
Hand tools such as screwdrivers, the reliability, safety and long service life of which depend on the elasticity and at the same time the hardness of their shafts, are manufactured from specially alloyed tool steel, which makes it possible to achieve higher strength due to their higher content of selected elements. The molybdenum content of the tool steel Premium Hard chrome/vanadium steel results in their higher durability, tensile strength and ductility, while the increased silicon content ensures their higher elasticity and lower susceptibility to cracking. The appropriate hardness and resistance to wear are achieved with a corresponding carbon content.

Specially alloyed tool steel 73MoV52, according to EU directive 2000/53/EC

• 0.60% manganese for higher tensile strength and ductility
• 1,15% silicium for higher elasticity and lower susceptibility to cracking
• 0.70% carbon for appropriate hardness and resistance to wear

Cold-forged steel with high quality characteristics ensures that profiles now have an even longer-lasting strength, with shafts of extraordinary hardness.

For optimal grip and cutting strength
Steel with a medium carbon content is particularly suitable for pliers due to its incorporation of selected alloyed elements. Together with the hardness achieved through inductive tempering, this material property allows for extraordinary clamping strength. Pliers made of various improved steels have a suitable hardness and higher tensile strength, due to their higher carbon content. Manganese also contributes towards improvement, as it increases the ductility of the material. Silicon was used to improve the elasticity of the material, while chrome reduces its susceptibility to cracking.

Alloyed tool steel C45E, in accordance with EU Directive 2000/53/EC and the EN 10083-1 standards

• 0,45% carbon for higher tensile strength and ductility
• 0,70% manganese for higher tensile strength and ductility
• 0.30% silicium for higher elasticity
• 0,30% chrome for lower susceptibility to cracking and higher tensile strength

Pliers with optimal, inductively hardened jaws are characterised by excellent clamping properties, an outstanding grip and flexible joints.

Alloyed tool steel C60E, in accordance with EU Directive 2000/53/EC and the EN 10083-2 standards

• 0,60% carbon for higher tensile strength and ductility
• 0,70% manganese for higher tensile strength and ductility
• 0.30% silicium for higher elasticity

The design and manufacturing quality of high-quality steel pliers with special properties ensure efficient pinching off of hard wire.

Efficiency and durability under considerable crushing and deformation stress
Construction and trade steels have special properties that guarantee their appropriate hardness, ductility and elasticity, as is required for tools such as setters, hammers and screw clamps, which are exposed to great force during hammering and clamping. Steels with a medium carbon content that are used to make tools have a higher carbon content, resulting in better durability. A suitable manganese content increases the tensile strength and ductility of the material, which is particularly important under high load conditions. The chrome content reduces the susceptibility to cracking, while the silicon content increases the elasticity of tool materials subjected to strong forces.

Medium carbon steel C45R, according to EU directive 2000/53/EC and the EN 10083-2 standards

• 0,45% carbon for higher tensile strength and better tempering
• 0,70% manganese for higher tensile strength and ductility
• 0,35% chrome for higher tensile strength and lower susceptibility to cracking
• 0,20% silicium for higher elasticity

Hammer
Steel with higher tensile strength reduces the possibility of new cracks forming on impact faces.

Puller body
A steel tool with a high carbon content that can withstand high pull-off forces. High-quality material and well-designed manufacturing ensure strength and durability.

Effortless cutting
In addition to carbon, manganese, silicon and chrome, this special carbon steel also contains vanadium, which considerably improves the pinching characteristics of the tool by increasing its carbide hardness. Pincers made from this steel prove their excellent efficiency, even when used on the hardest of wires. The high carbon content results in both a higher tensile strength of the material and in increased durability. Improvements made subsequent to the inductive forging process lead to extraordinarily high jaw hardness.
