The Biggest Mistakes Buyers Often Make While Selecting a High-Speed Steel Supplier

Selecting the best quality HSS, or high-speed steel supplier, is no less important than choosing the proper steel grade for any given application. Any wrong step in choosing your steel grade can lead to a number of issues. This might range from early tool failure, delays in production, inconsistency in hardness and eventually costly repair and replacement. However, there are different ways to avoid this problem if you remain vigilant while choosing your steel, as well as your material supplier. Here's a quick guide in this regard.

Don't Judge by the Price

Setting a budget is indeed important before choosing a supplier. And there are times when you might need to complete a project on a tight budget. However, choosing a partner solely on the basis of their packages might cost you dearly in the long run. Often, the low-cost varieties do not meet the necessary chemical composition. They might also lack cleanliness and fail to meet metallurgical parameters. Choosing inferior-grade steel can lead to uneven heat treatment, inconsistent carbon distribution, and also compromised wear resistance and early tool breakage. Such issues can give way to expensive replacement and increased downtime. Hence, the trick is not to judge a supplier on the basis of the rate he asks for per kilogram. You would rather determine a supplier on the basis of:

• Expected tool life
• Performance in machining
• Expenses in  heat treatment
• Efficacy in production

Ignoring the Certificates

A number of clients ignore the importance of material certification. However, a seasoned client always looks for the following:

• Mill Test Certificates or MTCs
• Reports of chemical composition from competent authorities
• Necessary documentations for material traceability

Apart from these, on the basis of your unique requirements, you can also ask for reports on:

• Material hardness
• Ultrasonic testing
• Latest metallurgical inspection

Apart from these, inspection certificates such as EN 10204 Type 3.1 can also be relevant, particularly when there is some provision in your purchase agreement.

These documents can help you verify the material properties. They also boost confidence in the quality of the materials and the consistency of your supplier.

Ignoring Stock Availability and time of delivery

Your production schedule is likely to suffer if there is any unavailability of the necessary materials. So before choosing a supplier, check their stock updates. At least, check their available stock of the most common tool steel varieties like:

• M35
• M2
• M42

Also, check whether they are available in desired sizes, dimensions and shapes, such as flat bars, round bars, and square bars.

Apart from these, while placing the order, you need to check for other essential parameters like:

• Despatch timelines
• Terms and conditions of despatch
• Logistics services
• Availability of cutting services
• Ability to handle emergency supplies when the need arises.

Going by the Salesmen

A responsible High Speed Steel supplier would identify your true requirements and suggest necessary materials. Since different types of High Speed Steel have different chemical compositions, not all of them can be equally effective for your needs. So if you meet a supplier who seems to be pushy about their materials and supplies, then you might need to reconsider before taking the deal forward.

Finally, a reliable service provider would be happy to answer all your queries and co-operate. Anyone not accommodating to your queries would be best avoided.
