Fundamentals of Heat Treating and Plating Fasteners and Other Small Components About the Seminar: Benefits of Attending This two-day seminar was developed for engineers and technical Gain an understanding of what is occurring when a fastener is heat treated personnel to gain a high level, broad understanding of why and Become familiar with the common heat treating processes how fasteners and other similar items are heat treated and plated for fasteners or coated. The demands on today’s fasteners are ever increasing Understand when to specify specific processes or equipment and these two process steps play a critical role in how well the Recognize potential failures modes fastener will perform its intended function. Gain an understanding of the benefits of different platings and coating This seminar will begin by exploring the fundamental metallurgical Understand when to specify certain plating or coating pro- transformations and principals that yield the mechanical changes cesses desired by the fastener designer or engineer. Each process will Gain insight into plating and coating performance and rela- be examined in greater detail to understand how the process tive cost to achieve these goals achieves these underlying principals and what practical effects it Explore current issues in regulation and environmental protection has on the fastener. Control points will be investigated to gain an understanding of, not only how the process remains in control, but also how it can go wrong and the consequences when it does. Concepts Covered

Day two will explore platings and coatings. There are a multitude Metallurgical transitions of good options today and this seminar shall look at those favored Hardenability by large fastener consuming industries. In addition to gaining an Quench and Temper understanding of the plating or coating system, this seminar shall explore the application processes, significant control points, how Austempering they impact fastener performance and common pitfalls and errors. Case Hardening

Unlike most of the processes utilized in manufacturing fasteners Annealing which have changed little in recent years, this seminar shall explore how the plating and coating processes and options are evolving Induction Hardening rapidly to address ever increasing demands for performance and Furnace Types friendliness to the environment.

Tempering Who Should Attend: Heat Treating Control Points Fasteners are used extensively in every industry. Since the Heat Treating Potential Failure Modes mechanical performance and physical characteristics are, in Electroplating fact, critical in many instances, this seminar is very beneficial to Barrier Coatings professionals that are working on design, development, application Crystalline and Oxide Finishes engineering, fastener procurement, and quality assurance. If you are involved in the fastener supply chain or are an end user and Mechanical Plating seek to gain a better understanding of the fundamentals of heat Dip Spin Finishes treating and plating of fasteners, this course is designed especially Plating Potential Failure Modes for you.
