ASTM A182 F347H Stainless Steel Flanges

ASTM A182 F347H Stainless Steel Flanges

SA 182 Grade F347H Weld Neck and Slip On Flanges manufacturer in Mumbai, India

A182 F347h is the higher carbon version of the alloy. It is emerged for enhanced creep resistance and for higher strength at temperatures above 1000°F. It is a high carbon austenitic chromium stainless steel which is useful in the applications that demands high temperature resistance. It has the high carbon composition form of alloy and demonstrates improved creep properties and high temperature.

F347h exhibits good general corrosion resistance. It is produce for use in the chromium carbide precipitation range of 800 – 1500°F where un-stabilized alloys such as ASTM A182 F304 are subject to intergranular attack.

The hardenability of ASTM A182 Gr F347h can be minimized by the use of constant positive feeds and slow speeds. It is useful for applications such as chemical processing, pharmaceutical production, food processing, petroleum refining, etc. Upsetting, forging, and other hot work processes of Material A182 F347h can be performed at 1149 to 1232°C. In order to obtain its maximum hardness it has to be water quenched and annealed.

SA 182 F347h can be readily blanked, stamped, spun and drawn as it is quite ductile and tough. It can be annealed at temperature ranging from 1010 to 1193°C and then quenched with water. It is unresponsive to heat treatment. The hardness and strength of it can be increased by cold working.
