AISI 304 Pipe Fittings Manufacturers (1.4301, S30400)  | (1.4306, 1.4307, S30403), Buttweld Fittings, Forged Fittings, Flanges

Metline is one of the largest and most renowned manufacturing and stockholding company in India, supplying all types of SS 304 pipe fittings including buttweld fittings, flanges and forged fittings. Given our extensive expertise and knowledge in stainless steel industry we can offer stainless steel 304 pipe fittings, at the most competitive prices in the Industry. Grade 304/304L (UNS S30400/S30403, EN 1.4301/1.4307) is most widely used Austenitic stainless steel. Grade 304L is a low carbon 304, which is a common practice for 304L to be dual certified as 304 and 304L. The low carbon chemistry of 304L combined with an addition of nitrogen enables 304L to meet the mechanical properties of 304. Grade 304L often used to avoid possible sensitization corrosion in welded components.

UNS Designation & International Equivalent for SS 304 Pipe Fittings

Type 304 stainless steel is the most versatile, and one of the most widely used of the 300 Series stainless steels, with excellent forming and welding characteristics.

Heat Resistance of Stainless Steel 304/304L Pipe Fittings

Good oxidation resistance in intermittent service to 870°C and in continuous service to 925°C. Continuous use of 304 in the 425-860°C range is not recommended if subsequent aqueous corrosion resistance is important. Grade 304L is resistant to carbide precipitation and can be heated into this temperature range.

Heat Treatment of Stainless Steel 304/304L Pipe Fittings

Solution Treatment (Annealing) Heat to 1010-1120°C and cool rapidly. These grades cannot be hardened by thermal treatment.

Welding of SS 304/304L Pipe Fittings

Excellent weldability by all standard fusion methods, both with and without filler metals.
