Why to pay extra if you have choice to get exact sizes and wall thickness in UNS S30400 Sanitary SS Tube

For sanitary applications that require a cost-efficient alloy, stainless steel grade 304 is one of the best sought after. Usually cold worked, the ASTM A270 TP304 Sanitary Stainless Steel Tubes find major utility as structural components. Typically, industries like the food and beverage, medical, pharmaceutical, as well as the biological industry make use of the ASTM A270 TP304 Sanitary Stainless Tubing. Since these materials are required to be hygienic and non-reactive, metals are to be chosen accordingly.

Although grade 316 is a very popular choice, the use of UNS S30400 Stainless Steel Sanitary Tubes is noted across several factories for two reasons. First, the cost of using this material is low. Second, the availability of the astm a270 tp304 alloy across the globe makes it easy to procure the tubes. Generally, the materials that are used to produce these tubes need to be sterile at all times. Hence, the ASTM A270 304 Sanitary SS Tube is often sterilized with the use of heat and alkaline cleaning agents, none of which react to the material. The sterilization of these A270 TP304 Sanitary Tubes may be carried from several times a week to several times a day, depending on the industry.

To maintain sterility in the equipment, often these ASTM A270 TP304 Tubing components have their surface treated with finishes or with mechanical processes to make their surface smoother. A smooth surface in both the interior and the exterior of the ASME SA270 TP304 Tube aids in a better transitioning of the product. Furthermore, a smoother surface guarantees a cleaner surface as no residue is left on the walls of the ASTM A270 TP304 Tube.
