347 Stainless Steel
Introduction
Overview of 347 Stainless Steel
347 stainless steel is an austenitic low-alloyed steel that has a minimum strength of 100 ksi (690 MPa) and a maximum carbon content of 0.15%. Its tensile strength can be increased by cold working it.
347 stainless steel is similar to 302 and 303, but has a higher carbon content and greater strength and hardness at elevated temperatures. It is used for high temperature applications such as heat exchanger tubing and boiling water heaters.
