Product Introduction

Alloy 347H (UNS S3409) is a high carbon, niobium-containing Cr-Ni austenitic stainless steel and is a high carbon (0.04 – 0.10) version of Alloy 347. 347H Stainless Steel Plate was developed for enhanced creep resistance and higher strength at temperatures above 1000°F (537°C). Excellent high temperature oxidation resistance in intermittent service up to 1600°F and continuous service up to 1700°F. Commonly used in chemical processing, petrochemical and aerospace industries.

347H Stainless Steel Plate Fabrication and Heat Treatment

Hot Working: Forging, upsetting, and other hot working processes can be performed at temperatures between 1149 and 1232°C (2100 and 2250°F). AISI 347H must be water quenched and annealed to obtain maximum hardness.

Cold Working: 347H stainless steel is very tough and ductile and can be easily stamped, blanked, spun, and drawn.

Annealing: Alloy 347H stainless steel can be annealed at temperatures between 1010 and 1193°C (1850 and 2000°F) and then quenched with water.
