Niagara Specialty Metals has built its reputation in the portion of the steel industry where performance alloys become workable material. Its focus has been the conversion and processing of specialty steels into sheet and plate with consistent thickness, flatness, and condition, so customers can machine, heat treat, and manufacture with predictable results from one lot to the next.

Niagara was founded in 1982 in Akron, New York, by J. Barry Hemphill and Louis Valery. The region’s industrial base, transportation access, and skilled trades workforce supported a business model centered on specialty rolling and processing rather than high-volume commodity production. Niagara entered the market to serve customers who needed tool steels and stainless steels in gauges, widths, and quantities that large mills and standard distribution channels were not structured to deliver quickly. Its early niche centered on custom sizing, short-run flexibility, and reliable turnaround.

As Niagara matured through the 1980s and 1990s, its work broadened into a wider range of specialty alloys. The operational discipline required to process tool steels supported expansion into other demanding grades used across specialized manufacturing, including aerospace- and electronics-adjacent materials. Over time, Niagara also expanded beyond rolling alone. Customers frequently require post-rolling processing that brings the sheets and plates into a condition ready for manufacturing, and those requirements become more stringent as alloy content rises and tolerances tighten. Niagara developed additional capabilities around its rolling operations so customers received material that behaved consistently on the shop floor.

The knife market’s modern shift toward powder metallurgy also increased demand for PM tool steels and PM stainless steels in forms that makers could work with. In that context, steels such as CPM 3V, CPM 4V, CPM M4, CPM 10V, and CPM 15V became common reference points, while stainless PM steels such as CPM S30V, CPM S35VN, CPM S45VN, CPM S110V, and CPM S125V represented different approaches to balancing corrosion resistance and wear resistance. Across both categories, a consistent supply of usable sheet and plate became part of what determined which steels were adopted widely.

That supply chain was disrupted on December 12, 2024, when Crucible Industries filed for Chapter 11 bankruptcy protection. Crucible had been manufacturing CPM powder steels for decades, and the filing created uncertainty around continuity for widely used grades. In 2025, Erasteel acquired most of Crucible’s patents and key assets tied to its powder metallurgy steel business, creating a pathway for ongoing production. Continuity still required material to move into sheet and plate through established processing and distribution channels, and Niagara’s role in that period involved distributing Crucible steels for Erasteel and supporting availability into the market.

This transition also brought changes to familiar steel names. Niagara purchased CPM CruWear and CPM S90V and carried them forward under new designations. CPM CruWear became NSMWear, and CPM S90V became NSM 90PM. The performance profiles of these steels were already established for knife makers, but the original CPM naming could not continue under previous agreements Crucible had in place with other companies, so the steels moved forward under Niagara’s NSM designations.

Taken together, Niagara’s history reads as a steady expansion of capability rather than a series of reinventions. Since 1982, the company has remained focused on the same practical problem: supplying high-performance steels in usable sheet and plate on time, with the consistency manufacturers require. That role has placed Niagara at the center of industries that depend on tool steels and specialty alloys, and it has also made the company increasingly visible to knife makers as modern blade steel supply has shifted toward higher-alloy and powder metallurgy grades. In the wake of Crucible’s bankruptcy and the transition of key PM steels into new ownership and naming structures, Niagara’s position as a processor and distributor has become one of the stabilizing links that keep established and new materials available to the market.
