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.

Heat Resistance of Stainless Steel 304/304L Pipes

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 Pipes

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

Welding of SS 304/304L Pipes

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