MTS Forge delivers precision-normalized alloy steel flat bars engineered for demanding industrial applications. Our in-house normalizing heat treatment produces refined, uniform grain structures — ensuring consistent mechanical properties, superior tensile strength, and enhanced machinability. Serving aerospace, defense, power generation, and beyond from our Coatesville, PA facility, we bring 40 years of metallurgical expertise to every bar we produce.
From normalizing heat treatment to rough machining and sawing, we offer comprehensive capabilities for alloy steel flat bar production.
In-house normalizing services heat forged components above their upper critical temperature, then allow controlled air cooling to produce a refined, uniform microstructure with consistent tensile strength, toughness, and machinability throughout the part.
Custom-forged flat bar products crafted to exact customer specifications across a wide range of alloy steel grades, delivering high-quality, dimensionally accurate components for aerospace, defense, power generation, and industrial applications.
In-house rough machining removes excess material from as-forged flat bars to achieve near-net shape, eliminating forging flash and dimensional excess while reducing lead times and the need for separate machining vendors.
Precision sawing services for alloy steel flat bar stock up to 16 inches in outer diameter, enabling accurate cut-to-length capability that supports downstream processing and reduces material waste.
Electric eye contour burning services for alloy steel materials up to 8 inches thick, providing accurate profile cutting for flat bar blanks and custom shapes required in specialized industrial applications.
Special forgings in alloy and stainless steel grades manufactured to stringent quality standards including Mil I 45208, NCA 3800, and Mil Q9858, supporting nuclear, defense, and high-specification industrial procurement requirements.
We begin by confirming the appropriate alloy steel grade for your application — whether 4140, 4340, or another specification — reviewing chemistry certifications and ensuring full traceability from mill source to finished flat bar, consistent with our Quality Assurance Program requirements.
For 40 years, MTS Forge has combined metallurgical expertise with in-house capabilities to deliver normalized alloy steel flat bars that meet the most demanding specifications.
Founded by metallurgists with deep forging knowledge, we understand alloy steel behavior at every stage of the normalizing process.
Our Coatesville, PA facility performs normalizing heat treatment in-house, giving you faster turnaround and complete process control without third-party delays.
Our Quality Assurance Program — covering Mil I 45208, NCA 3800, and Mil Q9858 — ensures complete traceability and compliance for aerospace, defense, and nuclear procurement requirements.
Every normalized alloy steel flat bar is produced at our Pennsylvania facility, supporting domestic supply chain requirements for defense and government-regulated industries.

Co-Founder
Stephen Carr co-founded Manufacturing & Technical Services, Inc. (MTS Forge) in 1986 alongside Edward Waddell, driven by a shared vision to deliver high-quality forged solutions to America's most demanding industries. With a strong metallurgical background and extensive hands-on knowledge of forging practices, Stephen has been instrumental in shaping MTS Forge's technical capabilities and quality culture. Under his leadership, the company developed robust Quality Assurance Programs compliant with Mil I 45208 and NCA 3800, enabling MTS Forge to serve commercial nuclear, defense, aerospace, and power generation clients. His commitment to precision, traceability, and craftsmanship continues to define the standard for every carbon steel forged flange that leaves the Coatesville, PA facility.
Co-Founder
Edward Waddell co-founded MTS Forge in 1986, bringing a strong metallurgical background and a wealth of forging knowledge that has guided the company's growth over nearly four decades. Edward played a foundational role in establishing the principles of quality and service that remain central to MTS Forge's identity today. His technical expertise spans a wide range of forging processes and materials, enabling MTS Forge to serve industries from commercial nuclear and defense to power generation and chemical processing. Edward's vision helped build a facility in Coatesville, PA capable of delivering carbon steel forged flanges, special forgings, and custom components with the precision and traceability that critical industry sectors demand.
Normalized 4140 refers to AISI 4140 alloy steel — a chromium-molybdenum grade — that has been subjected to the normalizing heat treatment process. The steel is heated above its upper critical temperature (typically around 1600–1700°F) and then cooled in still air at room temperature. This process refines the grain structure created during hot working or forging, producing a uniform, fine-grained microstructure with consistent tensile strength, improved toughness, and better machinability compared to the as-forged or as-rolled condition. Normalized 4140 flat bars are widely used in aerospace, defense, and power generation components.
