Key steel, h9
No items found.

Bars of bright key steel play an essential role in many different mechanical and industrial applications, allowing for power transmission, as well as keeping parts in place. A4 stainless steel key bars made to DIN 6880 are particularly known for their high precision and sturdiness.

What is key steel?

Key steel is used to make keys - mechanical components which are in turn inserted into specially designated grooves in two mechanical components to lock them together, thus allowing for effective torque transmission and preventing relative movement between the parts.

DIN 6880 standard

The German industry standard DIN 6880 lays out the necessary dimensions, tolerances and materials for key steel. This standard ensures that key bars are compatible and interchangeable, making for efficient installation and operation in mechanical systems.

Technical specifications of h9 steel

h9 tolerance

h9 tolerance means a high degree of dimensional accuracy for bright key steel, ensuring a perfect fit in the grooves (keyways) on mechanical components. Such precision is vital for applications where reliability and security are required.

Properties of h9 steel

h9 steel is the ideal combination of hardness, wear resistance and durability, making it an excellent choice for key steel. It is designed to withstand shear and torsional forces, offering reliable performance even in harsh conditions.

Applications for h9 key steel

Power transmission

Keys made from h9 key steel are widely used in power transmission systems to fasten shafts to hubs, gears, and pulleys, so that torque can be transmitted effectively.

Industrial machinery

h9 key steel can be used to maintain alignment and fasten rotating components in industrial machines, making sure they work smoothly and safely.

Automotive & aeronautics

Our bars of h9 key steel can be used to make essential components (i.e. keys) for steering systems, engines and transmissions in both motor vehicles and the aeronautical industry, where reliability and safety are paramount.

Advantages of h9 key steel

Precision & compatibility

With their h9 tolerance, these steel bars offer exceptional dimensional accuracy, allowing for perfect compatibility with DIN 6880 standard mechanical components.

Stability & durability

h9 steel is extremely robust and durable, capable of withstanding high loads and harsh operating conditions for extra long-lasting joints.

Wear-resistance

These h9 steel bars for keys boast excellent wear resistance, minimising the need for frequent maintenance and replacements, and making them a cost-effective, reliable choice for a range of industrial applications.

How do I choose the right key steel?

Things to remember when choosing the right bar for your needs

When choosing a key steel, you should take into account:

  • Dimensions: The dimensions should match up with the keyways on the components.
  • Material: The type of stainless steel should be chosen based on load and operating conditions.
  • Standards: Make sure the bar complies with relevant industry standards, such as DIN 6880.

Remarks regarding h9 key steel

h9 key steel is an excellent choice for applications that require high precision and robustness. Their dimensional tolerance and excellent mechanical properties make them ideal for harsh industrial environments.

Installing keys made from h9 steel bars

Install steps

  • Preparation: Make sure the keyways are clean and free of debris.
  • Inserting the key: Insert the key into the keyway.
  • Assembly: Slide the hub or pulley onto the shaft, aligning the groove (keyway) with the key.

To install a key, make sure you have a:

  • Hammer: To insert the key into the keyway.
  • Punch: To properly align the key in the keyway.
  • Gauge: To check dimensional tolerances.

Application case studies


Key success stories

Various companies in the manufacturing, automotive, and aeronautical sectors can testify to the effectiveness of h9 key steel in their everyday operations.

Increasing productivity

Businesses have noted that using DIN 6800 key steel bars has significantly reduced their downtime and maintenance costs.


Conclusion

In short, h9 key steel, manufactured to DIN 6880, is essential in a wide range of industrial applications. Its precision, sturdiness and wear resistance makes it an ideal choice for power transmission and fastening rotating components.
