 304N Stainless steel Introduction

304N Stainless Steel , 304N Stainless plate, ASTM SS304N, Stainless 304N

Type 304N is an extra low-carbon variation of Type 304 with a 0.03% maximum carbon content that eliminates carbide precipitation due to welding. As a result, this alloy can be used in the “as-welded” condition, even in severe corrosive conditions. It often eliminates the necessity of annealing weldments except for applications specifying stress relief. It has slightly lower mechanical properties than Type 304.
304N Stainless steel Usage
Chemical industry equipment; industrial tanks; general application medical instrument; tableware kitchenware; architectural purpose; milk&food processing acidities,; hospital equipment; bath-tub; reflector; mirror; interior-exterior decoration for building; architectural purposes; escalators; kitchenware vehicles.
