ATI alloy selected for North Sea offshoreproject

EOS unveils new laser sintering machineEOS has developed a new laser sintering machine for precious metals.

PRECIOUS M 080 from EOS can make parts out of 18 ct yellow gold for the jewel-lery and watch industry. The system was developed in partnership with Cookson Precious Metals ,CPM, a supplier for the precious metal industry. Based on a strategic partnership, both companies plan to introduce and further develop precious metal-based applications to the jewellery and watch industry. The product and services offerings will range from consulting, direct metal laser-sintering, or DMLS-based design processes, the production of precious metal parts and the development and production of special precious metal alloys for the additive manufacturing process. They also plan to develop a bespoke solution chain for high-volume jewel-lery production.

“With this technology, 3D bespoke jewellery and watch components can be created from CAD files,” said Stella Layton, CEO of Cookson

Precious Metals. “ This takes us on an exciting journey, permitting the creation of highly complex and intricate designs that weren’t think-able before. The particular beauty of additive manufac-turing is that it can be used to produce both one-off pieces as well as large-scale production, eliminating many process steps and tooling costs that we see today.”

“With CPM we found a perfect partner to introduce our innovative technology to the luxury goods industry, thus shifting paradigms in manufacturing,” said Dr Adrian Keppler, EVP strategy and business development at EOS. “We truly believe that our AM process offers huge potential for these indus-tries. Compared to conven-tional manufacturing tech-niques, it paves the way for a completely new approach towards design and manufac-turing.”

The technology enables time savings, thus lowering the general costs of entry into the business of making quality jewellery and watch parts in precious metal.

EOS’ machine can make parts for the jewellery industry.

(ATI) says that its ATI 2003 lean duplex stainless alloy has been selected for a range of of topside structural components for a major offshore project in the Norwegian North Sea.

ATI 2003 lean duplex stain-less was chosen over 316L stainless and coated carbon steel for topside secondary and outfitting structural com-ponents in order to improve corrosion resistance and reduce weight.

“ATI 2003 alloy creates value for our customers by

providing opportunities for significant cost savings and strength-to-weight advan-tages compared to materials currently employed,” said Rich Harshman, chairman, president, and CEO of ATI.

ATI 2003 lean duplex stain-less steel is a molybdenum-enhanced, proprietary duplex stainless alloy. It has a Pitting Resistance Equivalency number (PREn) of 30 and is a more corrosion-resistant, higher strength, and cost-effective material for new plat-forms in the harsh North Sea environment, according to ATI.

The ATI alloy is resistant to harsh, corrosive environments.

American National Carbide launches range of nano-coated carbide insertsNew ‘Synergy’ line features a substrate improved with a nano coating technology, American National Carbide

says.The new inserts feature

a substrate improved with a nano coating technol-ogy so that it can work at the elevated temperatures (common when machining superalloys).

Synergy also offers: a func-tional 100° roughing corner for enhanced productivity;

coolant flow channel for efficient temperature regula-tion; positive ground land to reduce cutting forces; multi-ple obstructions for optimal chip control; helical land angle to resist DOC notching; mechanical post-treatment to reduce friction; post-coating surface grind for maximum stability; and wide chip breaking range.

ANC offers three styles: general purpose, finishing, and roughing.
