PT-7MSV Titanium: Industrial-Grade Titanium Alloy for Demanding Applications
PT-7MSV Titanium a high-performance titanium alloy developed for the most demanding industrial applications, including heat exchangers, nuclear power systems, and marine equipment. At Russian Steels, we offer PT-7MSV titanium in various forms such as plates, sheets, bars, and forgings, designed to meet the rigorous requirements of industries that need exceptional strength, durability, and corrosion resistance.It exhibits moderate strength (≈ 480–680 MPa), high elongation (15–30%), and low density (4.49 g/cm³). PT-7M is easily deformable both at room and elevated temperatures, and annealing in the α-region maintains its mechanical balance. The alloy resists corrosion in marine, chemical, and high-temperature aqueous environments due to the stable TiO₂ oxide film it forms.
What is PT-7MSV Titanium?
PT-7MSV Titanium (also known as Grade 7 titanium) is a wrought titanium alloy primarily composed of titanium with zirconium and small amounts of tin. It is designed for applications where superior corrosion resistance and mechanical strength are essential. Commonly used in chemical processing, aerospace, and nuclear industries, PT-7MSV titanium offers exceptional performance under extreme conditions.
Typical applications include chemical apparatus, marine structures, and components in nuclear or heat-exchange systems. However, it is not suitable for high-strength load-bearing parts and must be protected from hydrogen embrittlement. Overall, PT-7M combines light weight, formability, and corrosion resistance, prioritizing durability over maximum strength.
