Metallurgy for Blacksmiths
with Paul Kovach
and Tom Farraro
Our meeting was educational and indoors out of the heat (and there was no rain today) at Stress Engineering Services Conference Center and featured two expert metallurgists discussing heat treatments and metal alloys with a select Bill Moran video and BBQ in between. We had a great question/answer session about metals!
Steel and Its Heat Treatment
Stress Engineering Services
Steel consists of iron and one or more other alloying elements. Iron, as is true for all metals, is crystalline when solidified. Iron is somewhat unique since it undergoes changes in its crystal structure when heated and cooled through specific temperature ranges. When alloyed, especially with carbon, these crystal structure changes are used to harden, strengthen, and toughen steel by various thermal cycles. These crystal structures, their changes, and general properties will be described. The bases for various heat treatments will be covered for fuller understanding of what is actually happening when iron or steel is heated, forged, slow cooled, quenched, and tempered.
Paul's presentation slides are available for download in two parts (1.4 Mb pdf each):
Effect of Alloying Elements on the Properties of Steels
Stress Engineering Services
All steel tools and knives are made from alloys which are a combination of iron, carbon and other elements. Each alloying element has a specific effect on the steel properties of strength, ductility, hardness, wear resistance, corrosion resistance etc. During this presentation we will discuss the specific effect of alloying elements typically used in tool and knife steels and how to select the best alloy depending on the end use of the tool.
Tom's presentation is available for download (1.4 Mb pdf) by clicking Tool Steel Alloys.
Tom recommends these web sites as a good source of the information he presented:
General Information Selection of Tool & Die Steels , and the book The Metals Black Book Vol 1 - Ferrous Metals (the one with the black book cover) from CASTI.

HABA's newest Board Memnber Mark Finstad brought several of his recent projects to show. We will have a future meeting on the design process of the candle stand featured in the photos below.
HABA Banner and Stand for ABANA Conference
Les Cook has been working on our banner stand for the ABANA Conference. He brought the stand and set it up outside. Frank Walters is working on the banner. Les sent this report:
The stand has an oil and agriculture theme, which would symbolize our Texas heritage. Richard Boswell donated the seed materials of 1” sucker rod. John Korb has donated ľ” and ?” sucker rod. Tim Bailey has donated time and talent in doing machine work and design advise. Lee Oates is donating his expertise in doing scrollwork and along with David Hoffman had good design input. Robert Killbuck has donated his welding skills. Brian (Well this is interesting) Bateman has contributed with a number of hours as a striker and with design input. Les Cook has headed the project and designed the stand.
Our intent is to have the banner and stand at the next HABA meeting on June 19. We would like all members that have touch marks etc. to bring them so we can put your mark on the stand to represent the membership. For those without marks we could put your initials on it.
Friday night the 18th update: Lee had completed the scrollwork with help from David “Bulldog” Hoffman and the top section was complete. All the parts were assembled in my driveway and Brian “WTI” Bateman dropped by to assist and take pix. To my “unbiased eye”, it looks great.
A GREAT BIG THANK YOU TO ALL THAT HAVE CONTRIBUTED TO THIS PROJECT!!

Paul Kovach has M.S. Metallurgy from M.I.T. in 1962 and B.E. Cum Laude, from Youngstown State in 1960. He is a Senior Metallurgical Consultant with Stress Engineering Services where he is an expert in failure analysis especially evaluation of fracture surfaces to determine modes of failure. This includes material behaviors under static, dynamic, creep, fatigue, and impact loading. He is also epert in oxidation and corrosion in flue gases, seawater, and a wide variety of produced and process fluids. He is an expert in weldability and welding procedure development, and materials selection and applications in industries such as petrochemical, power generation, oil and gas production, nuclear, pipeline, and transportation.
Tom Farraro is a Consultant with Stress Engineering Services and has a B.S. Metallurgical Engineering from University of Texas with 25+ years experience in the oil and gas industry specializing in management, evaluation, maintenance, and continuous improvement of mechanical integrity and reliability of pipelines and storage tanks in refineries, petrochemical plants, lube oil refineries, ethylene & polyethylene plants, oil and gas pipelines, LNG facilities, and oil & gas production facilities. Equipment types evaluated include pressure vessels, tanks, pumps, compressors, piping systems and pipelines, boilers, furnaces, marine loading facilities, docks, and production wells (wellheads and downhole equipment) both offshore and onshore. Areas of technical expertise include fitness for service evaluation, metallurgical and corrosion engineering, non-destructive testing, welding engineering, chemical treatment (process, water, and downhole) metallurgical/corrosion failure analysis, risk based inspection.
The 13800 Westfair East SES main building is on the corner of Westland West and Westfair East. There are several other Stress buildings along the curved street Westland West from Eldridge to Westfair East.
Enter by the side entrance and park on the east parking lot on Westland West.
