Enhanced Properties for Bright 17-7 PH Stainless Steel

  Source:  Today’s Medical Developments

Already extensively used in aerospace, semiaustenitic stainless steel 17-7 PH is finding new applications in the medical industry. The material is most often used in sheet and strip form, with springs, clips, and bellows being widely produced. The high alloy content of 17-7 provides excellent corrosion resistance, an attractive attribute to the medical industry.

Orthodontic Industry Purchases Blue M Convection Oven from TPS

Thermal Product Solutions (TPS), a global manufacturer of thermal-processing equipment, announced the shipment of a Blue M Ultra-Temp Standard Convection Oven to the Orthodontics industry. The convection oven will be used for a metal injection molding debind process at temperatures of 390°F and 1050°F.

The Blue M oven work chamber is 48” W x 24” D x 36” H and has a maximum temperature rating of 1300°F. The customer’s parts will be placed on ceramic trays then run through the debind cycle that usually lasts 14 to 16-hour cycle. The process off gasses some non-hazardous fumes that condense into a form of wax. The parts are loaded into the oven via a lift truck.

The oven has a powered exhaust with VFD for pulling out non-hazardous fumes coming from the products during the de-binding process. The VFD will enable the customer to adjust the exhaust motor speed to reduce or increase the exhaust flow rate.

Unique features of these Blue M ovens include:

  • Powered exhaust
  • Reinforced chamber floor to hold up to 500-lbs distributed load
  • 6-inch high angle iron floor stand to raise the oven and allow customer to insert their lift truck under the oven to load their product into the oven work space

“For suppliers, the other way to get involved is obviously through getting audited for accreditation. If you’re interested in an audit, the process is fairly straightforward. Once in contact with MedAccred, a supplier details their products and figures out what categories they should be applying for.”

Effect of Heat Treatment on the Tensile Strength of ‘Elgiloy’ Orthodontic Wire

BOTW-50w  Source:  Dental Materials –

Elgiloy is the trade name of a cobalt–chromium–nickel superalloy that is offered for orthodontic use as wire. Despite some years of use, there is very little information in the dental literature on its mechanical properties, and especially on the effect of the hardening heat treatment (HT), that may be used after forming, on the tensile strength (TS) in relation to the four ‘tempers’ that are available.

New Brazing Audit Criteria Released by MedAccred

In response to industry demand, the MedAccred program has recently released new audit criteria for brazing. AC8102/1 MedAccred Audit Criteria for Heat Treating – Brazing will be used during MedAccred audits conducted at companies performing brazing in an atmosphere or vacuum furnace or  in a dip salt bath.

The new audit criteria were developed by the MedAccred Heat Treating Task Group which is comprised of technical experts from Johnson & Johnson, Stryker, GE Healthcare, Medtronic, Applied Thermal Technologies, Bodycote, Harterei Gerster, Hansen Balk, Lake City Heat Treating, Paulo Products and Solar Atmospheres. To date the Task Group is one of the most successful within the MedAccred program. It has released six audit criteria in total and has several companies who have already achieved accreditation; these include Solar Atmospheres, Hansen Balk and Bodycote.

The industry chairperson of the Heat Treating Task Group is Bruce Dall, Senior Staff Quality Engineer – Metal Injection Molding of Stryker. He is very proud of the achievements of the program to date:  “I would like to thank my fellow members of the Heat Treating Task Group for their hard work and the commitment they have shown in the development of these new audit criteria for brazing. In most other environments we are competing organizations but when we come together as a MedAccred Task Group, we are able to put aside our rivalries in the interest of quality and working towards consistently safer products for our patients. The fact that we are now seeing suppliers stepping forward to pro-actively gain a Heat Treating accreditation MedAccred is a strong indication of how important this program will be to the future of the industry and I am proud to be at the forefront of this effort.”

Companies interested in gaining accreditation for Heat Treating are encouraged to contact Justin McCabe, MedAccred Co-Lead (jmccabe@p-r-i.org) for more information. Companies achieving accreditation will be listed on MedAccred’s Qualified Manufacturers List (located at www.eAuditNet.com).

“According to the U.S. Energy Information Administration, manufacturing accounts for one-fifth of the annual energy consumption in the United States – approximately 21 quintillion joules (20 quadrillion BTU) or equivalent to 3.6 billion barrels of crude oil. To reduce this staggering amount and improve sustainability, manufacturers need to accurately measure and evaluate consumption of energy and materials, as well as environmental impacts, at each step in the life cycles of their products.”
