SS 347/347H Sheets & Plates



These sheets and plates are manufactured by using premium quality of alloy and as per the set manufacturing norms and product quality standards. This SS sheet plate is designed and offered to the clients in different standards, wall thickness, widths, etc to easily satisfy different demand of various applications in industries. With regard to the industry standards, we are providing these sheets and plates in custom-made specifications and standards. Our product is conforming to product quality standards like AISI, ASTM, API, ASME, etc. Stainless steel alloy 347 or UNS S34700 is the columbium stabilized austenitic stainless steel material. It is having very good resistance ability against general corrosion and to some extent very good resistance ability into the strongly oxidizing atmospheres. It is having commendable resistance ability against intergranular corrosion once got exposed to the temperature into the chromium carbide precipitation ranging 427-816 deg C. The alloy is having very good resistance to oxidation and creep strength to temperature 816 deg C. It is also offering commendable low-temperature hardness. Stainless steel 347H or UNS S34709 is the greater carbon version of SS 347 alloy, in the proportion of 0.04% to 0.10%. It is developed for enhancing the creep resistance and for the greater strength at the temperature range of 1000+ deg F. Stainless Steel 347 / 347H Sheet Plate is widely appreciated due to many good properties. Some properties are high tensile-yielding strength, ability to hold high temperature and high pressure, anti-corrosive body, general corrosion resistance, pitting and oxidation resistance, high hardiness, rugged construction, sturdiness, etc. These UNS S34700 and UNS S34709 sheets and plates are used in many industrial applications. It is including petrochemicals, pharmaceuticals, specialty chemicals, chemical industry, pharmaceutical industry, offshore oil drilling industry, pulp & paper industry, automobiles, constructions, buildings, food and gas processing, etc. These plates and sheets are very well quality checked to make sure that no poor quality of the product is delivered to the clients. The tests are intergranular corrosion tests, macro tests, mechanical strength tests, chemical tests, etc.
