What is SS 303 Flanges?
Stainless Steel 303 Flanges are highly versatile steel flanges crafted from an alloy primarily comprised of chromium, nickel, and manganese. This alloy imparts a corrosion-resistant structure, where chromium forms a passive layer on the surface, enhancing its inherent resistance to corrosion. Moreover, SS 303 Flanges exhibit outstanding machinability, making them suitable for a diverse range of applications demanding strength, heat resistance, and thermal stability.
These flanges offer an exceptionally robust and corrosion-resistant material that is cost-effective without requiring extensive heat treatment, while also boasting excellent machinability. Their strength, flexibility, and toughness make AISI 303 Stainless Steel Flanges ideal for various applications, including fastening components such as nuts and bolts, pressure control devices, and pumps. Additionally, their robust properties make them widely utilized in piping systems, capable of withstanding higher pressure, temperature fluctuations, and exposure to harsh chemicals.
Specialized melt processing further enhances the thermal stability of 1.4305 Stainless Steel 303 Flanges, making them an excellent choice for extreme working conditions like cryogenic environments or high-temperature chemical processes.
Lakshya International specializes in the production of Stainless Steel 303 Flanges, offering a diverse range of shapes and sizes tailored to meet specific specifications and customer needs. Our commitment extends to fulfilling the extensive global demand from customers spanning across 6 continents and approximately 96 countries.

What is stainless steel 303?
Stainless steel 303, also known as grade 303, is a highly machinable austenitic stainless steel. Its machinability is attributed to the presence of Sulphur in its composition.
What are the standards for stainless steel flanges?
Stainless steel flanges, denoted as SS flanges, are made from materials such as ASTM A182 Grade F304/L and F316/L. Common pressure ratings range from Class 150 to 2500.
Stainless Steel 303 Flanges Price?
The price for Stainless Steel 303 Lap Joint Flanges typically ranges from Rs. 100 to 40,000 per kilogram.
Why use 303 stainless steel?
Grade 303 is chosen for its exceptional machinability among austenitic stainless steel grades, attributed to the presence of Sulphur. However, it comes with a trade-off, as the Sulphur content reduces corrosion resistance and slightly lowers toughness.
