Precipitation Hardening Stainless Steel Market Report 2026

The precipitation hardening stainless steel market size has grown strongly in recent years. It will grow from $10.95 billion in 2025 to $12 billion in 2026 at a compound annual growth rate (CAGR) of 9.6%. The growth in the historic period can be attributed to growth in aerospace manufacturing, increasing defense spending, adoption of stainless steel in oil and gas equipment, demand for corrosion-resistant medical components, advancements in heat treatment technologies.

The precipitation hardening stainless steel market size is expected to see strong growth in the next few years. It will grow to $17.08 billion in 2030 at a compound annual growth rate (CAGR) of 9.2%. The growth in the forecast period can be attributed to expansion of electric and hybrid vehicle platforms, rising demand for lightweight high-strength materials, growth in next-generation aerospace programs, increasing use in advanced medical devices, focus on performance materials for extreme environments. Major trends in the forecast period include rising demand for high-strength corrosion-resistant alloys, growing adoption in aerospace structural components, increasing use in high-performance automotive parts, expansion of precision heat treatment processes, rising preference for long-life materials in harsh environments.

The increasing rates of aircraft production are anticipated to drive the growth of the precipitation-hardening stainless steel market. The surge in aircraft manufacturing is fueled by rising air travel demand and efforts to modernize fleets, as airlines seek to accommodate more passengers and replace outdated, less efficient planes. Precipitation-hardened stainless steel is preferred for aircraft components due to its high strength, corrosion resistance, and lightweight properties, making it suitable for critical parts such as landing gear and engine components. For instance, in June 2023, Boeing, a U.S.-based aircraft industry leader, projected robust demand in the global aviation sector, with a need for 42,595 new commercial jets valued at $8 trillion by 2042. The global fleet is expected to nearly double to 48,600 jets, growing at a rate of 3.5% annually. Over 75% of these new deliveries will consist of new single-aisle airplanes, surpassing the 2022 outlook and totaling more than 32,000 units. Hence, the rising aircraft production rates will stimulate the growth of the precipitation-hardening stainless steel market.

Leading companies in the precipitation hardening stainless steel market are concentrating on developing innovative solutions, such as stainless steel powder, to enhance material properties, boost manufacturing efficiency, and address the rising demand for strong, corrosion-resistant components. Stainless steel powder is a finely divided form of stainless steel made up of microscopic particles that typically range from a few micrometers to under 100 micrometers in size. For example, in June 2023, Uniformity Inc., a U.S.-based materials technology firm, introduced UniJet SS17-4PH Stainless Steel Powder, an advanced material created for additive manufacturing applications. This powder consists of 17-4PH stainless steel, a widely utilized precipitation-hardening alloy, and offers excellent particle flow, uniform microstructure, and high tensile strength after printing and heat treatment. Its uses include aerospace components, medical devices, and high-performance industrial parts, delivering advantages such as reduced post-processing, improved part density, and enhanced corrosion resistance compared with traditional PHSS manufacturing methods.

In February 2024, North American Stainless (NAS), a U.S.-based stainless steel production facility under the Acerinox Group, acquired Haynes International, Inc. for $970 million. This acquisition is intended to bolster growth in high-performance alloys, especially in industries such as aerospace and chemical processing, where Haynes has a strong market presence. Haynes International Inc. is a U.S.-based manufacturer specializing in high-performance alloys, including precipitation-hardened stainless steel.
