ASTM A240 SS310S Stainless Steel Plate and Sheet or Coil with Highly Quality
ASTM A240 SS310S Plate and Sheet or Coil
Overview
Stainless steel 310S plates are flat plates made of iron, chromium and nickel alloys with low carbon content. This gives the 310S high corrosion resistance and oxidation resistance at high temperatures, making it suitable for high temperature environments such as furnace parts, heat treatment equipment and exhaust systems. Available in a variety of sizes and thicknesses, 310S boards can be cut, molded and welded to suit specific applications. Stainless steel 310S panels are ideal for a variety of residential and industrial applications. They offer many advantages in terms of strength, durability and corrosion resistance.

310S Stainless Steel Sheet Finish/ Plate Finish
- No. 2D - A smooth, non-reflective cold-rolled annealed and pickled or descaled finish.
- No. 2B - A smooth, moderately reflective cold-rolled annealed and pickled or descaled finish typically produced by imparting a final light cold-rolled pass using [large diameter] polished rolls.
- Bright Annealed [BA] Finish- A smooth, bright, reflective finish typically produced by cold rolling followed by annealing in a protective atmosphere so as to prevent oxidation and scaling during annealing.
- No. 3 Finish is characterized by short, coarse, parallel polishing lines, which extend uniformly along the length of the coil.
- No.4 Finish is characterized by short, parallel polishing lines, which extend uniformly along the length of the coil. It is obtained by mechanically polishing a No. 3 finish with gradually finer abrasives.
- No.7 Finish has a high degree of reflectivity and a mirror-like appearance. A No. 4 finish that has been polished to 320-grit is buffed for up to 10 minutes but existing grit lines are not removed. The remnants of fine polishing lines can generally seen by an observer standing several feet from a panel.
- No.8 Finish It is produced in the same manner as the No. 7 finish except that the buffing is continued for an additional five to ten minutes. In comparison to a No. 7 finish, the grit lines are much less visible, but they can be seen if the finish is examined closely. The resulting finish is mirror-like but not a perfect mirror.
