ASTM A270 Tubing

ASME SA 270 Stainless Steel Pipe and ASTM A270 Sanitary Tube

The ASTM A270 grade encompasses standard welded, seamless, and heavily cold-welded austenitic and ferritic grades designed for sanitary applications. Our ASTM A270 Tubing is crafted with varying chemical compositions to enhance resistance to corrosive and oxidative agents in challenging environments. The ASTM A270 Sanitary Tube is available in sizes up to 12 inches with a maximum outer diameter of 300mm, exhibiting robust strength that withstands stress-induced conditions. The versatile A270 Sanitary Stainless Steel Tubing can be both hot and cold-rolled to achieve desired characteristics. Our institution is dedicated to supplying top-quality products, facilitated by collaborations with various logistical and supply chains, ensuring swift product delivery.

 The ASTM A270 Stainless Steel Seamless Tubes stand out as some of the most robust tubes in this category. Produced through an extrusion process involving the passage of hot steel billets through metal, these tubes lack seams on the surface, enhancing their load-bearing capacity.

The ASME SA 270 Stainless Steel Pipe is engineered for high-temperature and pressure applications, offering resilience under diverse conditions. The A270 Stainless Steel Tubing is weldable using automated procedures, eliminating the need for filler material. Prior investigation is recommended to ensure suitability for use in challenging conditions. To acquire our products or learn more about our offerings, feel free to visit any of our outlets or contact us for additional information.
