SS 347 fittings manufacturer, ASTM A403 WP347H elbow/ tee/ reducer

Are you looking for SS 347 fittings in specific size? Check out our inventory of ASTM A403 WP347 Elbow and Tee

Creative Piping Solution Pvt Ltd introduces Stainless Steel 347/347H Pipe Fittings, adhering to ASTM A403 and ANSI B16.9 standards. Comprising iron, chromium (17-19%), nickel (9-13%), and columbium for enhanced corrosion resistance, these fittings, with UNS S34700 (347) and UNS S34709 (347H), and DIN WNR. 1.4550 and 1.4961 respectively, undergo rigorous in-house testing, including Hydrostatic and Positive Material Identification.

Distinguishing features lie in design nuances: Stainless Steel 347, fortified with columbium, excels in resisting intergranular corrosion. In contrast, Stainless Steel 347H, with a higher carbon content (0.04%-0.10%), caters specifically to elevated-temperature applications, providing improved high-temperature strength. These differences highlight adaptability to specific operational requirements, showcasing versatility in various industrial settings.

In critical applications across chemical and petrochemical industries, their resilience within a recommended temperature range from cryogenic to 900°C underscores their technical prowess in craftsmanship and durability.
