Cutting tool. Designation of high-speed steel groups ICS 25.100.01 J41 National Standards of People's Republic of China Replacing GB/T 17111-1997 High-speed steel cutting tools grouping code (ISO 11054.2006, MOD) Posted 2008-06-03 2009-01-01 implementation Administration of Quality Supervision, Inspection and Quarantine of People's Republic of China Standardization Administration of China released

Foreword

This revised standard adopts ISO 11054.2006 "high-speed steel cutting tools Group Code" (in English). This standard is based on ISO 11054.2006 redrafted. This standard and ISO 11054.2006 compared with the following technical differences and editorial changes. --- Remove the foreword to international standards, increase the standard of this preface; --- With a decimal point is used instead of ",". ","; --- Increase in conventional high speed steels of low alloy high-speed steel code HSS-L, which provides high-speed steel and general distinction, in Example, increased sample of HSS-L; --- In high speed steel HSS-E groupings, increasing the containing aluminum (Al) grouping method; --- Table 1 adds the name of high-speed steel; --- Added Appendix A. This standard replaces GB/T 17111-1997 "high-speed steel cutting tools grouping code." This standard and GB/T 17111-1997 There are technical differences compared to the following. --- Increasing the terms and definitions; --- Table 1, increasing the name of high-speed steel, an increase of high-speed steel powder metallurgy code; --- Table 1, in the conventional high-speed steel adds low-alloy high-speed steel code HSS-L, it specifies the distinction between ordinary high-speed steel method; --- In high speed steel HSS-E groupings, increasing the containing aluminum (Al) grouping method; --- Increase the sample; --- Added Appendix. Appendix A of this standard is an informative annex. The standard proposed by China Machinery Industry Federation. This standard tool by the National Standardization Technical Committee (SAC/TC91) centralized. This standard was drafted. Chengdu Tool Research Institute, Shanghai Tool Works Co., Ltd., Harbin Measuring & Cutting Tool Group Co., Ltd., Chengdu Into a tool Limited, Harbin first tool Manufacturing Co., Hanjiang Tool Co., Ltd., Metallurgical Technology Co., Ltd.

This standard superseded standard previously issued as follows. --- GB/T 17111-1997. High-speed steel cutting tools grouping code

1 Scope

The standard provides for the manufacture of cutting tools, such as taps, drills, end mills and other high-speed steel grouping code. This standard does not specify high Speed \u200b\u200bsteel component which shall be prescribed by GB/T 9943. This standard applies to high-speed steel cutting tools used for classification.

2 Terms and definitions

The following terms and definitions apply to this standard. 2.1 By conventional ingot smelting process to produce high-speed steel. 2.2 Produced by powder metallurgy high-speed steel. Code 3 High-speed steel cutting tools packet code according to Table 1. In addition to the standard code, the manufacturer can increase the additional code to further explain their products. Table 1 high-speed steel grouping code Production process grouping method code name Conventional high speed steel High speed steel HSS-E The amount of cobalt or vanadium content ≥4.5% ≥2.6% or aluminized Volume ≥0.8% ~ 1.2% of high-speed steel HSS HSS Cobalt content < 4.5% and vanadium content < 2.6%, and tungsten when High-speed steel output [W] a≥11.75 of Low-alloy high-speed steel HSS-L equivalent tungsten [W] < 11.75, the high-speed steel and ≥6.5 Powder Metallurgy High Speed \u200b\u200bSteel High-performance powder metallurgy high-speed steel HSS-E-PM Cobalt content ≥4.5% or ≥2.6% of the amount of vanadium-containing powder Metallurgy High Speed \u200b\u200bSteel Normal powder metallurgy high-speed steel HSS-PM Cobalt content < 4.5% and vanadium content < 2.6% containing powder Metallurgy High Speed \u200b\u200bSteel equiv a tungsten [W] is calculated. [W] = W + 1.8Mo, W. tungsten content is lowest, Mo. molybdenum content is the lowest value. Example 4 Example 1. In accordance with the conventional production process, in line with GB/T 9943 high-speed steel of W4Mo3Cr4VSi, tungsten equivalent [W] 8, code-named. HSS-L Example 2. In accordance with the conventional production process, in line with GB/T 9943 HSS W6Mo5Cr4V2, cobalt content of 0%, 2% containing vanadium, tungsten equivalent [W] as 13.6, code-named. HSS ...
