SS 304 / 304L / 304H Pipe
Stainless Steel Grade 304 is the most versatile and widely used stainless steel in the world. Ashwin Steel supplies an extensive inventory of 304, 304L (Low Carbon), and 304H (High Carbon) pipes. Known for its excellent corrosion resistance, formability, and weldability, the 304 series is the standard choice for countless commercial and industrial piping systems.
Our 304 pipes easily withstand atmospheric corrosion and a wide range of organic and inorganic chemicals. The 304L variant eliminates carbide precipitation during welding, making it ideal for heavy-gauge welded components, while 304H provides superior strength at elevated temperatures.
