In addition to undergoing several mechanical tests such as flattening, flange, hardness, reverse bend, tension, and hydrostatic or nondestructive electric, the ASTM A249 304 Welded Tubing the grain size of this particular alloy grade can be determined by these tests. Apart from resisting atmospheric corrosion, the SA 249 Tp 304 Equivalent material has good resistance to moderately oxidizing and reducing environments as well. One of the benefits of using the Welded 304 Stainless Steel Tubing is that in comparison to the other stainless steel alloy, the tubes produced from SA 249 Tp 304 are cheaper, thereby proving to be an economical choice for several applications. Trade named UNS S30400, the Sa-249 Welded Tubing is one of our more popular products. Get in touch with us for the price of ASTM A249 Type 304 High frequency induction welded steel tubing Ex Mumbai.
