Stainless Steel 17-4 PH Strip, Sheet & Plate is a versatile and high-performance precipitation-hardening stainless steel alloy. It combines excellent mechanical properties with moderate to good corrosion resistance. Labdhi Metals, a reputed manufacturer, stockist, and exporter, supplies high-quality 17-4 PH stainless steel products in various forms, including strips, sheets, and plates, catering to a wide range of industrial applications worldwide.
Labdhi Metals ensures precision manufacturing and compliance with global standards like ASTM A693 and AMS 5604. Their 17-4 PH sheets and plates are known for their superior flatness, surface finish, and tight thickness tolerances. The material can be heat treated to achieve high strength and hardness, making it ideal for aerospace, defense, marine, nuclear, and chemical processing industries.
17-4 PH stainless steel, also designated as UNS S17400, achieves its strength and hardness through a combination of martensitic transformation and precipitation of copper phases. It provides excellent mechanical strength, especially in the H900 to H1150 heat treatment conditions, while also offering resistance to stress corrosion cracking and oxidation.
The material’s corrosion resistance is comparable to that of 304 stainless steel in most environments, but with significantly higher strength. It is widely used in manufacturing parts such as structural components, turbine blades, fasteners, springs, shafts, and molds where both corrosion resistance and high mechanical performance are critical.
