Foreword
This standard replaces GB/T 3879-1983 "steel bonded carbide material blanks."
This standard compared with GB/T 3879-1983, mainly in the following changes.
--- Increasing the preface and the normative references content;
--- Modify the original standard series code and presentation rules;
--- Modify the product model and represents a rule;
--- Improving the blank dimension control accuracy requirements, while increasing the forged and machined blank blank state dimensional control accuracy requirements;
--- Remove the rough fracture surface curvature requirements and the requirements of the circular blank roundness requirements and plate;
--- Increasing the test results to determine the content;
--- Increased orders (or contract) content requirements.
