It points out the advantages of segregating heats of tubing and mapping the tube-heat locations.
WebNote: 1.4307 and 1.4404 are low carbon stainless steels with reduced risk of sensitization and improved weld corrosion resistance when section thicknesses greater than about 3 mm are welded. When producers have state-of-the-art production methods, commercially produced stainless steels are often low carbon and 'dual certified' to both designations.
