Stanley alloys are the popular manufacturers and suppliers of Stainless Steel 347 flange. We import and export superior quality products for our valuable clients. Grade 347 approaches great resistance to corrosive environments and crevice corrosion. This Stainless Steel 347 flange is made from national and international standard quality. We offer the same product according to the customer's required specifications, such as wall thickness, sizes, surface finishes, and forms.

The production of flanges has become effective with the sincere dedication and efforts from our team and professional experts by ensuring products of high quality of alloy and also provides high resistance to acid attacks, usually by sulfuric, phosphoric and nitric acids. We use modern technology and the latest tools that enhance the production of flanges.

Alloy 347 Flanges maintains stainless steel and plates and provides many benefits such as outstanding resistance to intergranular corrosion by temperature exposure in chromium carbide rapidity ranges up to 816℃. Alloys 347 Sheets are composed of Chromium, Nickel, Carbon, Manganese, Phosphorus, Sulfur, Silicon and Iron. Three hundred forty-seven plates of steel also have the addition of columbium and tantalum.

Hence, 347 is also referred to as Columbium Steel. Stainless Steel 347 flange also offers many good properties applicable for multiple purposes depending upon suitability. The most excellent properties are high tensile strength, good dimensional accuracy, superior surface finishes, rugged construction, anti-corrosive flexibility, long service life and reasonable maintenance cost, and, most importantly, high toughness. Therefore, grade 347 is also referred to as Columbium Steel.
