| NOTES (1) LF-2/A 105 – For each reduction of .01% below the specified carbon max, an increase of .06% manganese above the specified max will be permitted up to 1.35% max. (2) 304 / 304L & 316 / 316L – For some applications the substitution of type 304L for type 304, or 316L for type 316 may be undesirable because of design, fabrication or service requirements. | |||||||||||
