201 / 304 Stainless Steel Slit Edge Plate Etching Surface Finish
Type 201 Stainless Steel is an austenitic chromium-nickel-manganese stainless steel which was developed to conserve nickel. Type 201 is a lower cost alternative to conventional Cr-Ni stainless steels such as 301 and 304. Nickel is replaced by additions of manganese and nitrogen. It is non-hardenable by thermal treatment, but may be cold worked to high tensile strengths. Type 201 is essentially nonmagnetic in the annealed condition and becomes magnetic when cold worked. Type 201 can be substituted for Type 301 in many applications.

2. Etching What is etching ?
Etching is the process of using strong acid to cut into the unprotected parts of a metal surface to create a design in intaglio (image is created by cutting, carving or engraving into a flat surface) in the metal. As an intaglio method of printmaking it is, along with engraving, the most important technique for old master prints, and remains widely used today. In pure etching, a metal (usually copper, zinc or steel) plate is covered with a waxy ground, which is resistant to acid.
The artist then scratches off the ground with a pointed etching needle where he/she wants a line to appear in the finished piece, so exposing the bare metal. The plate is then dipped in a bath of acid. The acid "bites" into the metal, where it is exposed, leaving behind lines sunk into the plate. The remaining ground is then cleaned off the plate. The plate is inked all over, and then the ink wiped off the surface, leaving only the ink in the etched lines.
The plate is then put through a high-pressure printing press together with a sheet of paper (often moistened to soften it). The paper picks up the ink from the etched lines, making a print. The process can be repeated many times; typically several hundred impressions could be printed before the plate shows much sign of wear. The work on the plate can also be added to by repeating the whole process; this creates an etching, which exists in more than one state. Etching has often been combined with other intaglio techniques such as engraving or aquatint.
