Harsh Metalloys, a prominent manufacturer and supplier based in Mumbai, India, specializes in high-performance Stainless Steel 317 Pipes that are engineered for exceptional corrosion resistance and strength in challenging chemical environments. SS 317 is a molybdenum-bearing austenitic stainless steel, offering improved protection against pitting, crevice corrosion, and general corrosion when compared to standard 304/316 grades. These pipes come in seamless, welded, and fabricated forms, adhering to ASTM A312 and various international standards. Perfect for industries like chemical processing, pulp and paper, petrochemical, and marine, Stainless Steel 317 pipes deliver reliable performance even in harsh conditions involving acids, chlorides, and high temperatures.
Stainless Steel 317 Pipes are composed of roughly 18–20% Chromium, 11–15% Nickel, and 3–4% Molybdenum, which greatly enhances their resistance to chemical attacks. These pipes boast a tensile strength ranging from 515–750 MPa and a yield strength of about 205 MPa, along with impressive elongation and toughness. SS 317 retains its mechanical integrity in high-temperature applications, enduring temperatures up to 870°C (1600°F). It is non-magnetic in its annealed state and provides excellent workability, weldability, and formability, making it ideal for applications that involve pressure, corrosion, and significant thermal stress.

This provides exceptional strength, corrosion and reliability, which promises all the requirements of the industry.
When it comes to strength and resistance to corrosion, 317 square pipes really shine. They’re perfect for structural applications in places like chemical plants, marine settings, and high-temperature industrial systems.
If you’re looking for pipes that can handle acidic environments and high-temperature oxidation, 317 seamless pipes are your go-to. They’re particularly well-suited for chemical processing and the pulp and paper industry.
With their consistent wall thickness and impressive corrosion resistance, 317 ERW pipes are a great choice for medium-pressure systems in petrochemical, food processing, and water treatment applications.
For those tough corrosive and high-pressure environments, 317 LSAW pipes deliver reliable performance. They’re commonly found in oil and gas pipelines, structural supports, and for transporting industrial fluids.
Featuring high tensile strength and resistance to chemical attacks, 317 round pipes are ideal for exhaust systems, heat exchangers, and general industrial use.
When it comes to weldability and corrosion resistance, 317 welded pipes excel. They’re perfect for chemical processing plants, marine applications, and environments that experience high temperatures.
Stainless Steel 317 Pipes are extensively used in environments requiring superior corrosion resistance, such as in the chemical and petrochemical industries. These pipes are ideal for handling sulfur compounds, acidic solutions, and chloride-containing media. Common applications include heat exchangers, condensers, evaporators, marine systems, pulp and paper processing, and flue gas scrubbers. Their high molybdenum content provides better pitting resistance in chloride-rich environments than 316 pipes. SS 317 is also used in pharmaceutical equipment and food processing where hygiene and durability are essential. These pipes offer long-lasting performance, especially in systems exposed to harsh chemicals and high temperatures.
