Adinox Overseas is a well-known worldwide manufacturer, stockist, and exporter of high-quality Stainless Steel 347H Pipes, which has been made to fulfill the rigorous demands of industries working at high-temperature and corrosive conditions. SS 347H is a stabilized austenitic stainless steel grade containing columbium (niobium), which possesses superior resistance against intergranular corrosion. The carbon addition in the 347H grade has added strength in high-temperature conditions and it is useful in heat-intensive applications including boilers, heat exchangers, superheaters, and chemical processing equipment.
Our SS 347H Pipes are known extensively for their reliability in enduring harsh conditions when subjected to cyclic heating and cooling. These pipes find extensive application where high mechanical stress and high-pressure steam systems exist. These kinds of pipes from Adinox Overseas form part of our offerings ranging from seamless, welded, ERW and fabricated forms and conforming according to international standards like ASTM A312, A213, and A269.
