ASME SA 249 TP 316 Welded Stainless Steel Tubing

ASTM A249 316 ERW Tube exporter in India

Marine grade SA 249 Tp 316, when compared to conventionally used chrome-nickel steels, exhibit superior corrosion resistance properties, especially during exposure to corrosive compounds. A reason why Stainless Steel 316 Erw is considered superior to chrome-nickel steel grades is due to the addition of chromium to its alloy. Although similar to its austenitic counterpart alloy 304, the 316 Stainless Steel Welded Tubing has much better resistance to seawater and brine solution. Hence, the Welded 316 Stainless Steel Tubing is synonymous with marine engineering applications.

Moreover, apart from sulfuric acid containing solutions, the ASTM A249 316 Erw Tubing is resistant to halide compounds such as chlorides, bromides, iodides. The ASTM A249 Tp 316 Welded Boiler Tubes is also resistant to fatty acids, at elevated temperature settings. Further, the Sa-249 Tp316 does not lose its mechanical properties when used across a wide range of temperatures. As the alloy is non-toxic, the A249 Tp 316 Welded Tube is often used in those industries where the applications have zero tolerance for contamination. For instance, industries like textiles, pharmaceuticals as well as the food and beverage industry prefer using the ASME SA 249 Tp316 because of its non-contaminating properties.
