Stainless Steel 304/304L/304H Flanges

What is Stainless Steel 304/304L/304H Flanges

Stainless steel is considered as the strongest and most recommended material for the manufacturing of commercial as well as household alloys. Stainless steel has unique properties and characteristics that differs it from other alloys. Stainless steel 304 flanges are highly efficient and effective. These flanges are commonly used for industrial and plumbing purposes.

Flanges are generally used for creating permanent or temporary joints between two pipes in order to transfer material or fluids from one place to another. These flanges are used for long term purposes hence the quality and durability is the most prioritized considered feature. Grade 304L is the most demanded grade in all types of industries. Stainless steel 304H flanges are highly ductile and strong. These flanges are made of excellent quality raw material and alloys.

DIN 1.4301 Orifice Flange, ASTM A182 SS 304 Weldneck Flange, UNS S30400 Forge Flange, UNS S30400 Groove Flange, ASME SA182 SS 304 Socketweld Flange, DIN 1.4301 Lap Joint Flange, SS 304 Longweld Neck Flange.

Grade 304L flanges are made of excellent combinations. The chemical composition of this grade includes manganese, nickel, and chromium. The composition also includes some amount of silicon, carbon and phosphorus. These flanges are enriched with extraordinary properties. Grade 304H flanges are capable of tolerating high heat and bad weather conditions.

Stainless steel 304L flanges are enriched with high tensile and yield strength. We at Sumit impex make sure that our product is thoroughly tested and certified. We do multiple tests on all of our products to be sure about the quality of the product.
