Kiah Metallurgical Indian Exporters is a renowned manufacturer, supplier and exporters of SS 304 / 304L / 304H Flanges, which is the most common stainless steel. Stainless Steel 304 Pipe Flanges  contain both chromium (between 18 – 20 %) and nickel (between 8 – 10.5 %) metals as the main non-iron constituents. Stainless Steel 304L Pipe Flanges are defined as a Chromium-Nickel austenitic alloy and are the standard “18 / 8” stainless steel that you will probably see in your pans and other kitchen  tools. Stainless Steel 304H Pipe Flanges is the most versatile and most widely used stainless steel, available in a wider range of products, forms and finishes than any other. 304 Stainless Steel Flanges is a variation of the basic 18-8 grade, Type 302, with a higher chromium and lower carbon content. 304L Stainless Steel Flanges can be used in an “as welded” condition, while Alloy 302 must be annealed.

Stainless Steel 304/304L/304H Flanges

304H Stainless Steel Flanges has a carbon maximum is 0.030 and is the most versatile and widely used alloy in the stainless steel family. SS 304 Flanges is the most widely used commercial grade of stainless steel supplied into numerous industry sectors. SS 304L Flanges can be welded without the resulting issue of carbon precipitation. However, precipitation of chromium carbide as heat is applied during the welding process in SS 304H Flanges which depletes the chromium element of the steel thus reducing its anti – corrosive / oxidation effectiveness.
