Kalpataru Piping Solutions supplies premium 904L stainless steel pipes, known for their high alloy composition and low carbon content. This non-magnetic, austenitic stainless steel 904L pipe contains copper, making it highly resistant to strong acids like sulfuric acid. The low carbon content allows for easier production under ASTM A312 specifications, making it ideal for high-temperature applications.

With the addition of molybdenum, 904L pipes offer enhanced resistance to crevice corrosion, making them perfect for general corrosion applications and moderate to high-temperature conditions. Mechanical tests such as tension and flattening are performed on SS 904L pipes to ensure strength and durability. These pipes are heat-treated according to ASTM A312 standards for optimal performance.

904L stainless steel pipes offer a yield strength of 220 MPa, tensile strength of 490 MPa, and hardness of 70-90 , produced according to ASTM B673 specifications.

SS 904L pipe dimensions vary according to ASTM, ASME, and API standards. Seamless pipes range from ½ inch to 16 inches in nominal bore, ERW pipes range from ½ inch to 24 inches, and electric fusion welded pipes range from 6 to 100 inches. Overall, pipe sizes span from 1/8 inch to 30 inches. ASTM B677 UNS N08904 ERW pipes are available in various schedules, from SCH 20 to XXS, and come in seamless, welded, ERW, and LSAW forms.

904L stainless steel welded pipes are particularly well-suited for welding and are available with different end types such as plain, beveled, or threaded. As one of the leading 904L pipe suppliers and stainless steel 904L pipe manufacturers in India, Kalpataru Piping Solutions ensures high-quality products for various industrial needs.

The 904L stainless steel price varies depending on several factors, including market demand and material thickness. This high-quality alloy is generally more expensive than standard stainless steels due to its excellent corrosion resistance and durability.
