March 29 @ 11:00 am - 12:30 pm

Do you know Rockwell from Vickers from Knoop from Brinell?

11:00 AM – 12:30 PM (pacific)

Hardness is an essential property of all engineering materials – especially metals.

Fasteners made of metal derive their mechanical properties from processing that is designed to change their condition.

Sometimes it’s by heat treatment, sometimes it’s by cold working.

But no matter how the fastener arrives in its final condition, the way we know it is there is through examining it for hardness.

Understanding hardness in fastener is the key to understanding strength and performance.

This webinar will help inform you on all aspects of hardness as it relates to fasteners.

We will cover:

  • How to interpret hardness requirements in inch and metric fastener specifications.
  • The relationship between hardness and strength in fastener materials.
  • How does chemical composition affect hardness and hardenability?
  • What is special about hardness in non-ferrous materials?
  • What is the difference between hardness and hardenability?
  • What are the specifications that cover hardness testing?
  • What is core hardness and case hardness near-surface and what do fastener specifications require.
  • How is case hardness measured?
  • Understanding the various hardness tests and scales as they apply to fasteners.
  • What types of hardness tests are required from fastener standards and which are optional?
  • How to read fastener test reports to determine if the hardness is reported correctly.
  • When is it OK to convert hardness from one scale to another – and when it is not.
  • How exactly does hardness testing work?
  • Demonstrations of various hardness test methods – Macro Hardness, Micro Hardness and Superficial Hardness
  • What are the various types of equipment used to measure hardness?
  • How is hardness test equipment calibrated and certified?
  • When to use Non-Traditional hardness test methods.
  • Can a fastener supplier conduct their own hardness testing or must a lab be used?
  • How to properly prepare a fastener hardness specimen for testing.
  • How to properly prepare a fastener lab order for hardness testing.
  • When hardness testers lie – what are the most common hardness testing problems?
  • Hardness and Hydrogen Embrittlement Susceptibility.
  • Other important uses for hardness testing in fasteners.

As you can see – there are few things to know about hardness when it comes to fasteners.

Knowing them can make the difference between a profitable transaction and a fastener disaster.

Join us for this webinar and get up to speed on hardness!

This webinar will be Presented by Rob LaPointe and Carmen Vertullo of AIM Testing Laboratory.

The material is of a technical nature, but is appropriate for all levels of experience in the fastener industry.
