AM350 (АМ350)
AM350 Titanium Alloy for Industrial Machinery
AM350 is a precipitation-hardening stainless steel grade known for strong corrosion resistance, high tensile strength, and stable performance in demanding environments such as saltwater and chemical processing. It is weldable, formable, and retains strength across a wide temperature range, making it suitable for springs, fasteners, heat exchangers, and high-load components. In annealed, cold-worked, or heat-treated (aged) conditions, AM350 can reach very high strength levels (up to ~1700 MPa after aging, depending on processing). It is commonly selected for critical parts that require a balance of toughness, strength, and corrosion resistance at both sub-zero and elevated temperatures.Note: AM-350 is a stainless steel (not a titanium alloy). This page covers AM350 as a high-performance industrial grade and explains how Russian Metals supports supply and processing for such materials.
Why Choose AM350 for Industrial Machinery?
AM350 is used in industrial machinery because it offers an excellent combination of strength and corrosion resistance. It is often considered for components that face high stress, cyclic loading, moisture, or mild chemical exposure—where reliability and long service life are essential.
Although AM-350 is technically a stainless steel and not a titanium alloy, Russian Metals supports industries that use high-performance materials—such as AM-series stainless steels and titanium alloys—through supply, processing, and engineering support.

Advantages of Using AM350 in Industrial Machinery
AM350 is selected for industrial machinery because it supports long-term performance in challenging operating conditions, including:
- High Strength: Suitable for heavily loaded parts such as shafts, rotors, and fasteners.
- Corrosion Resistance: Performs well in humid, marine, and mild chemical exposure environments.
- Durability: Helps reduce maintenance frequency and improves service life of components.
Applications of AM350
- Marine: Used for corrosion-resistant components such as piping, valves, shafts, and fasteners in saltwater exposure.
- Heat Exchangers: Suitable for heat transfer equipment where strength and corrosion resistance are required.
- Power Generation: Used in turbine and compressor-adjacent components where temperature stability and strength matter.
- Automotive: Considered for high-performance assemblies where corrosion resistance and strength are important.
- Medical Devices: Used in certain equipment and instruments (application depends on certification/requirements).
- Food Processing: Applied in machinery and parts where hygiene and corrosion resistance support longer equipment life.
- Pharmaceutical Industry: Used for processing environments that require cleanability and resistance to mild chemicals.
- Industrial Machinery: Suitable for springs, fasteners, structural parts, and rotating equipment where strength is critical.
