Continuous Hot-Dip Aluminium/Silicon-Coated Cold-Reduced Carbon Steel Sheet of Commercial and Drawing Qualities
|Publication Date:||1 January 1993|
|ICS Code (Flat steel products and semi-products):||77.140.50|
This International Standard specifies the characteristics of cold-reduced carbon steel sheet of commercial and drawing qualities coated by a continuous hot-dip aluminium/silicon alloy coating process.(Footnote 1) This product is used principally for heat-resisting applications and also where corrosion resistance and heat are involved. The coating mass may be specified in accordance with table 2.(Footnote 2) This coating system normally produces a minimum layer of alloy. The coating mass is expressed as the total coating on both surfaces in grams per square metre. The coating mass specified should be compatible with the desired service life, thickness of the base metal and with forming requirements involved. A designation system (see clause 4) includes the coating designation, coating condition and quality.
NOTE 1 Values of total theoretical thickness for coating mass are given in annex A. A method for the determination of coating mass is given in annex B.
Commercial quality aluminium/silicon-co
Drawing quality aluminium/silicon-co
Drawing qualities are identified as follows:
02 Drawing quality
03 Deep drawing quality
04 Deep drawing quality special killed
Footnote 1 - This product is sometimes known as type 1.
Footnote 2 - Theoretical thicknesses for coating mass given in annex A are for information only.
