Kennametal has introduced its latest ceramic turning grade, KYHK15B, designed to deliver increased productivity and lower cost per edge in hard-turning operations. The new grade provides greater depth of cut capabilities than PcBN inserts when machining hardened steel, high-temperature alloys, and cast iron, as well as maximum tool life and wear resistance for the most…
What type of plastic is ideal for high-performance fasteners?
Written by Barbara Gerard, CEO Craftech Industries, Inc. Metal has long been the material of choice for mechanical fasteners. However, it’s no longer the go-to option for all design engineers. Depending on the application, the use of plastic is gaining popularity and offers several material advantages including strength, longevity, and cost-effectiveness. Plastic fasteners are now…
Material choices: When are plastic parts ideal?
Written by Barbara Gerard, • CEO Craftech Industries, Inc. Although most of the world’s fasteners are produced from metal, that choice is gradually changing for some engineers and designers. Depending on the application, a switch to plastic offers several material advantages. Plastic fasteners are typically lightweight and flexible, yet also strong, reliable, and cost-effective.…
How to reduce galling in stainless steel fastener applications
Screws threaded into blind tapped holes are commonly affected by galling and components made of stainless steel are especially susceptible. Stainless steel fasteners are widely used in corrosive environments for their superb corrosion-resistance but often suffer from galling and thread wear issues. Galling is a type of mechanical wear caused by a combination of friction…
A coating for galvanic corrosion prevention
Nylok, a provider of resin, adhesive, and lubricant coatings for threaded fastener applications, offers NYSHIELD — a coating that prevents galvanic corrosion between steel fasteners and extremely lightweight materials. NYSHIELD has minimal tension loss (even up to 150° C), exceptional chemical resistance, and adheres well to most substrates. Simply apply NYSHIELD uniformly to the steel…
What is stress relaxation in polymer fasteners?
By Julie Miller Polymers exhibit both viscous and elastic characteristics, or viscoelasticity — a powerful feature that offers distinct advantages. However, before choosing polymer fasteners, designers must weigh the effects of stress relaxation in polymers, which may cause joint failures over time. Stress relaxation is a gradual decrease in stress in response to constant strain.…
