STS Metals Strengthens Aerospace and Defense Capabilities with Valley Forge Acquisition

STS Metals

STS Metals, a leading specialty metals provider, has recently announced the strategic acquisition of Valley Forge, a prominent forged product manufacturer. This move is set to enhance STS Metals titanium forging capacity and solidify its position as a pivotal supplier in the aerospace and defense industries.

Expanding Capabilities and Portfolio

Valley Forge, located conveniently less than a mile from STS Metal's Sierra Alloys unit in Irwindale, California, is renowned for its expertise in producing forged round, flat, and ring products crafted from titanium and specialty alloy steels. With a robust infrastructure that includes a 1,000 short ton (st) open-die press and a rolling mill, Valley Forge offers a comprehensive suite of services such as heat treating, cutting, and machining.

The acquisition not only expands STS Metals product range but also integrates a sixth company into its burgeoning portfolio. This enhancement in operational capabilities is expected to bolster the company's offerings, particularly in flat products, as noted by Joe Kerkhove, Chief Commercial Officer at STS Metals. The addition of a third open-die press, alongside the existing 350st and 500st presses at Sierra Alloys, is aimed at broadening the dimensions and scale of production.

Strategic Market Positioning

This strategic expansion enables STS Metals to delve deeper into the defense sector and strengthen its ties within commercial aerospace supply chains. Valley Forge’s existing customer base, which includes original equipment manufacturers (OEMs), machine shops, and distributors, provides STS Metals with increased market exposure and business opportunities.

Looking forward, STS Metals is not planning to enter the rolled ring market; however, the acquisition will support its rolled plate operations through Valley Forge’s rolling mill capabilities. The company is also actively seeking further acquisitions to continue its growth trajectory, particularly targeting manufacturers that align with its aerospace metal product offerings.

Pratt & Whitney Titanium Certification Strengthens Sierra Sheet & Plate’s Aerospace Position

Pratt & Whitney MRO

Pratt & Whitney titanium certification has expanded STS Metals’ qualified supply base after the engine-maker approved Sierra Sheet & Plate’s flat-rolled titanium products for end-use applications. The certification allows purchase orders to go directly to Sierra Sheet & Plate, helping suppliers reduce lead times and procurement complexity.

The approval gives Sierra Sheet & Plate a clearer route into Pratt & Whitney’s aerospace supply chain. It also places the company alongside STS Metals’ Sierra Alloys and TSI Titanium as qualified titanium sources for the engine manufacturer.

Pratt & Whitney titanium certification matters because aerospace titanium qualification is difficult, costly and strategically important. Certified suppliers can support engine and airframe programs where material traceability, mechanical performance, heat treatment and surface quality must meet strict requirements.

Sierra Sheet & Plate Expands Qualified Titanium Supply

Sierra Sheet & Plate produces hot-rolled titanium plate and sheet in several titanium alloys, including 6Al-4V and 6Al-2Sn-4Zr-2Mo. These alloys are widely used in aerospace because they offer high strength, corrosion resistance and strong performance at demanding operating conditions.

The company also provides heat-treating, cutting and surface-finishing services. This gives buyers access to more complete processing capability, not only raw flat-rolled titanium material.

The MCL-LCS certification should improve procurement efficiency for Pratt & Whitney suppliers. Direct ordering can reduce unnecessary sourcing steps and help shorten delivery timelines in a market where aerospace material availability remains a recurring concern.

Aerospace Titanium Qualification Remains a Supply Chain Advantage

Pratt & Whitney titanium certification gives Sierra Sheet & Plate stronger credibility in the aerospace materials market. Engine supply chains require qualified sources that can meet repeatable quality standards and support long-term production schedules.

The certification also reinforces STS Metals’ broader titanium platform. With Sierra Alloys, TSI Titanium and Sierra Sheet & Plate now positioned as qualified titanium sources, the group can support multiple forms and processing routes within the aerospace titanium chain.

For titanium suppliers, qualification remains one of the strongest competitive barriers. As engine production and aftermarket demand continue to pressure aerospace supply chains, approved titanium plate, sheet and alloy sources will remain strategically valuable.

The Metalnomist Commentary

Pratt & Whitney’s approval shows that aerospace titanium supply is not only about capacity, but qualification. Sierra Sheet & Plate’s certification strengthens STS Metals’ position in a market where lead time, traceability and approved-source status directly influence competitiveness.

TITANIUM USA 2025: Global Titanium Hub Convenes in Boston

TITANIUM USA 2025

TITANIUM USA 2025 brought the titanium industry to Boston for three days of high-level exchange. Hosted by the International Titanium Association, TITANIUM USA 2025 gathered producers, processors, distributors, and end-users. Attendees used TITANIUM USA 2025 to network, share technology, and advance titanium supply chains.

Program showcases technology and networking

The conference delivered general sessions, workshops, and receptions across two days. Exhibitors and delegates held hundreds of business meetings on site. As a result, companies aligned on projects spanning aerospace, defense, and medical applications.

ITA anchors global collaboration and education

The ITA has connected buyers and technical experts since 1984. It promotes research, metallurgy, design, and engineering across the titanium value chain. Therefore, the association continues to build skills from shop floor to C-suite through publications and seminars.

Leading titanium companies underscored market depth in Boston. Timet, ATI, Carpenter Technology, and Perryman participated alongside technology firms. Meanwhile, STS Metals and IperionX highlighted innovations for high-performance components.

Titanium’s properties drive persistent cross-sector demand. High strength-to-weight ratios and corrosion resistance suit extreme environments. Consequently, titanium remains strategic for aircraft engines, implants, and industrial systems.

The Metalnomist Commentary

Boston’s gathering reinforced titanium’s role in mission-critical supply chains. Expect tighter partnerships between producers and OEMs as qualification needs rise. Education and process innovation will remain decisive differentiators in 2026 planning cycles.
