304L (UNS S30403): 18Cr-8Ni low carbon (C ≤ 0.030%). Mechanical guide: min tensile ~485 MPa (70 ksi), min yield ~170 MPa (25 ksi) typical for A312 TP304L — confirm PO.
Specify 304L when the PO calls for as-welded corrosion resistance. Dual-cert 304/304L is common in stock — still verify carbon and strength against the datasheet. For chlorides use 316L.
304L vs 316L: same low-carbon logic; 316L adds Mo for pitting. 304L vs 304H: opposite carbon strategy — do not substitute for high-temperature creep service.
