Stainless Steel Sheet Plate

Stainless steel sheet plates are flat-rolled steel products made from stainless steel. They are known for their high resistance to corrosion, strength, and aesthetic appeal. These plates are available in various grades, finishes, and sizes to suit different applications. The surface finish can range from a dull matte to a highly reflective mirror finish, depending on the specific requirements.

Finish (According to ASTM 480):

  • 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.

Always start grinding with a pullback motion instead of a push to reduce the chance of gouging this expensive material. Flap discs are another popular choice for working with stainless steel, because they grind and finish the workpiece in a single step.

The thinner the sheet, the easier it is to bend. Thin sheets can be bent by hand, while thicker sheets will require a bending tool.

Stainless steel plates have some obvious features when bending:

⒈Stainless steel is inferior to ordinary low carbon steel due to its thermal conductivity, and its elongation is low, resulting in a large deformation force;

⒉Stainless steel sheets have a strong tendency to rebound when bent compared to carbon steel;

⒊Due to the low elongation of the stainless steel plate, the bending angle R of the workpiece during bending is greater than that of carbon steel, otherwise, there may be cracks;

⒋Due to the high hardness of the SUS304 stainless steel plate, the cold work hardening effect is remarkable. Therefore, when selecting the bending tool, the tool steel with heat treatment hardness of 60HRC or more should be selected, and the surface roughness should be one order of magnitude higher than that of the carbon steel bending tool.

In combination with the characteristics of the above stainless steel, for the general bending:

⒈Under the unit size, the thicker the sheet, the greater the bending force required, and the margin of bending force should be larger when the bending equipment is selected as the thickness increases;

⒉Under the unit size, the greater the tensile strength, the smaller the elongation, the greater the bending force required, and the larger the bending angle should be;

⒊According to the experience, the unfolding dimension of a curved workpiece is equal to the right angle and the two plate thicknesses can be added to meet the design accuracy requirements. The calculation of the expansion amount according to the empirical formula can simplify the calculation. The process greatly improves production efficiency;

⒋The greater the yield strength of the material, the greater the elasticity and the amount of recovery. To obtain the angle of 90 degrees of the bending member, the angle of the required pressing knife should be designed to be smaller. Compared with the same thickness of carbon steel, stainless steel has a large bending angle. This should pay special attention to the occurrence of crushing cracks and affect the strength of the workpiece.

Stainless steel comes in a wide variety of forms and gauge. In most cases, the gauge of stainless steel determines its thickness. The tools you need to cut stainless steel depending on how thick your steel is. Here are some tools required.

  • Tin snips (suitable for thin pieces of sheets)
  • Power sheers (suitable for cutting thicker pieces of stainless steel sheet)
  • Circular saw
  • Angle grinder (suitable for thicker pieces of stainless steel sheet or tube)
  • Plasma cutter (suitable for extremely thick stainless steel bars, sheets, or tubes)

Watch Out for Overheating

As is true of all metals, cutting stainless steel can actually alter the atomic composition of the metal, resulting in changes to its appearance and performance. Welders have to be particularly careful when working with stainless to prevent overheating and problems related to contaminants.

  •  Cutting With Punch Sets
  •  Cutting With A Hole Cutter
  •  Using A Plasma Cutter
