Heat Treating Enables Handgun Conversions

Adam Devine, CEO, co-founder, and head of R&D, Ranger Point Precision

A Texas-based manufacturer of custom-built, match-grade rifles and performance parts for rifles and pistols recently announced that superior vacuum heat treatment capabilities result in the expansion of its line of parts for Steyr Arms Inc. A-1 pistols.

Ranger Point Precision, based near Houston, Texas, reported that their advanced heat treating process and salt bath black nitride allows for the conversion of any 40 S&W pistols to a .357 Sig, delivering match-grade accuracy, increased durability, reduced chamber friction, and extended barrel life. The expanded line includes both standard and threaded options along with thread protectors and mini-comps for .357 Sig / 9mm calibers.

“We start with premium Douglas barrel blanks with precise rifling, then use minimum spec chamber reamers, and the most advanced methods for heat treating and salt bath black nitride to produce the best Steyr pistol barrel available on the market,” said Adam Devine, CEO, co-founder, and head of R&D, Ranger Point Precision.

Steyr .357 pistol barrels are vacuum heat treated to 42 HRC and salt bath black nitride coated, giving them a surface hardness above 80 HRC.

Gas Supplier, Process Controls Group Launch Heat Treatment Collaboration

A global provider of industrial furnace controls and process automation solutions announced a new collaboration with a leading industrial gas company that combines the core competencies of each company into a comprehensive offering for heat treatment customers. Praxair Inc is based in Danbury, Connecticut, and produces and distributes atmospheric, process, and specialty gases and high-performance surface coatings. Customers will have access to Praxair’s gases, application technologies, and supply systems, along with United Process Control Inc’s portfolio of specialized industrial flow measurement and atmosphere control products. This continues the long-standing relationship between Praxair and Atmosphere Engineering Company, now a member of UPC, based in West Chester, Ohio.

The combined capabilities of the two companies will bring more end-to-end technologies for a broad spectrum of batch and continuous heat-treating processes such as carburizing, carbonitriding, neutral hardening, annealing, gas quenching, and heat-treatment applications under vacuum processing.

“The automotive and aerospace industries continue to expand requirements for heat treating,” said Steve Mueller, Praxair’s Associate Director of Business Development for Metals and Materials Processing. “We have a team approach in place, combining Praxair’s process know-how and expertise in industrial gases with United Process Controls’ specialized products. Together we meet customers’ requirements for high-quality heat treating with reproducible standards in their furnace operations.”

“This strategic agreement with Praxair reflects our commitment to offer the heat-treating industry a complementary and evolving portfolio of innovative technologies that help drive process efficiency and reliability. We look forward to working closely with Praxair in the coming years, as we strive to further increase our presence in North America,” said Paul Oleszkiewicz, President, UPC.

Rebar Micro Mill Planned in Florida

John Ferriola, Nucor chairman, CEO & president

The largest U.S. steel producer and “mini-mill” steelmaker recently announced plans to build a rebar micro mill near Frostproof, Florida, in a bid to capitalize on the growing demand for construction steel. The facility will produce steel rebar from scrap metal.

Charlotte-based Nucor Corporation will invest $240 million in the steel plant in Florida. The company began construction on its second rebar micro mill project in Sedalia, Missouri, in November 2017.

“Nucor has always focused on growing our business to better serve our customers. We are building this rebar micro mill in a great and growing market where demand is strong and there is currently an abundant supply of scrap, a good portion of which is handled by our scrap business,” said John Ferriola, chairman, CEO & president of Nucor Corporation. “Consistent with our planned strategy of being a low-cost producer, this micro mill will give us a cost advantage over our competitors who are shipping rebar into the region from long distances.”

The rebar micro mill, which will produce steel rebar from scrap metal, is expected to have an estimated annual capacity of 350,000 tons.

Dave Sumoski, executive vice president of Merchant and Rebar Products

“We would like to thank the many state and local officials, leaders, and partners who have assisted us with the project,” said Dave Sumoski, executive vice president of Merchant and Rebar Products. “Identifying the right location is an essential part of our rebar micro mill strategy, and this part of central Florida met all the criteria we evaluate. We look forward to becoming a member of the community.”

Endothermic Gas Generator Added to Brazilian Fastener Heat Treatment System

A major fastener manufacturer in South America recently received delivery of an endothermic gas generator intended for heat treatment operations at the company’s Brazilian plant.

Jomarca, a Brazilian producer of fasteners for the furniture, tooling, construction, and do-it-yourself markets, purchased the Atmosphere Engineering™ EndoFlex™ generator from United Process Controls (UPC) in reaction to doubled carburizing operations and increased production capacity. Carburizing operations now include ten large continuous rotary retort furnaces that process over 2200 US tons (2,000,000 kg) of fasteners a month.

The high-capacity generator was integrated into the plant’s existing gas distribution system in the first quarter of 2018 and is supplying endothermic gas to all carburizing furnaces. The EndoFlex operates at a lower cost and mixes to more accurate ratios, aimed at maintaining a constant furnace atmosphere and a consistent gas quality at all times. The enhanced control capabilities of the EndoFlex allow for continuous control and monitoring of CH4, dew point, differential pressure, gas temperature, and retort burnout, as well as data logging, which is critical for troubleshooting and meeting regulatory requirements.
