Type 316 was developed for use in sulfite pulp mills because it resists sulfuric acid compounds. Its use has been broadened, however, to handling many chemicals in the process industries. Type 317 contains 34% molybdenum (higher levels are also available in this series) and more chromium than Type 316 for even better resistance to pitting

surface creates a layer of dry paper in contact with the roll. Dry paper is a poor conductor of heat; indeed, it is a good insulator. This in effect insulates the moist part of the web from the hot dryer surface. Mass Transfer Once liquid water has been vapourized, it is necessary to transport the vapour through the web and out of the paper ...
CS products are temper rolled as a normal step in the mill processing. DRAWING STEEL (DS) For more severe forming applications, Drawing Steel Type B (DS Type B) should be ordered. DS Type B has a controlled carbon content of less than %C and is produced in such a manner that parts formed from DS Type B Steel should not exhibit stretcher strain.
