Cold-drawn steel products has the following advantages: Diversity of shape specifications Through the design of different shapes of the mold, cold out different section shapes, different tolerances of cold-drawn steel specifications. Angle can be designed straight or rounded corners. High accuracy company uses high-quality carbide die and mold repair professional staff to ensure the accuracy tolerance, unity. Smooth surface Advanced cold extrusion process makes the cold-drawn steel products surface smooth and bright. Steel and special steel two categories. a, common structural steel yield point using the representative phonetic alphabet "Q". The yield point value (in MPa) and quality level, deoxy method symbols, composed of grades in order. For example: carbon structural steel grade is expressed as: Q235AF, cold-drawn steel chemistry, Q235BZ; high strength low alloy structural steel grade is expressed as: Q345C, Q345D. Carbon structural steel grades composition, killed steel symbol "Z" and special killed steel symbol "TZ" can be omitted, for example: quality grade, respectively C and D levels of Q235 steel grade is expressed should Q235CZ and Q235DTZ, cold drawn steel 45 #, but can be omitted for the Q235C and Q235D. Low-alloy high-strength structural steel has killed steel and special killed steel, but grades tail without written symbols representing deoxy method. b, special structural steel commonly used on behalf of yield point steel symbol "Q", the yield point values ??and symbols represent products and other uses, said cold-drawn steel, for example: pressure vessel steel grade is expressed as "Q345R"; weathering steel the grade He expressed as: Q340NH. c, necessary, common grades of low-alloy high-strength structural steels may be employed two Arabic numerals (with very few dollars the average carbon content) and standard elements of symbols; grades are special low-alloy high-strength structural steel, in addition to general composition, there should be write as specified in Table 1 represent the product uses symbols.
