Harsh Metalloys, located in Mumbai, India, stands out as a top manufacturer and supplier of Stainless Steel 443 Pipes, celebrated for their remarkable resistance to corrosion and ability to endure high temperatures. This Grade 443 is a ferritic stainless steel alloy crafted to thrive in oxidizing environments and handle moderate corrosive conditions, making it a perfect choice for piping applications across various industries. Our SS 443 pipes come in both seamless and welded options, fully compliant with international standards like ASTM A312 and ASME SA312. With outstanding mechanical properties and excellent scaling resistance, these pipes play vital roles in power plants, petrochemical facilities, and industrial processing sectors.
When it comes to composition and mechanical properties, Stainless Steel 443 Pipes generally consist of 17–19% Chromium, low Carbon, and small amounts of Titanium to boost stability and corrosion resistance. Their ferritic structure provides impressive resistance to oxidation and stress corrosion cracking. SS 443 pipes boast tensile strengths around 515 MPa and yield strengths close to 205 MPa. They also maintain good dimensional stability at high temperatures and resist scaling in oxidizing environments. These pipes strike a perfect balance between strength, corrosion resistance, and formability, making them ideal for both structural and fluid transport applications in moderate to high-temperature settings.
