5.2 Thickness tolerance
Strip thickness tolerance of ± 0.020mm.
5.3 steel coil weight should be 6.0 to 12.0 tons.
5.4 Other dimensions, shape, weight and tolerances shall comply with the provisions of Q/BQB 401's.
6 Technical Requirements
6.1 Chemical composition
Determined by supply and demand after consultation with the parties.
6.2 Delivery Status
Cold rolling strip not annealed, not oiled state delivery.
6.3 steel hardness in delivery condition should HRB90 ~ HRB99, the average hardness value of three tests. supplier
Such as to ensure, without performing hardness test.
6.4 surface structure
Steel surface must be uniform and smooth appearance, the average surface roughness Ra≤0.7μm.
6.5 surface quality
6.5.1 steel surface may not have bubbles, scarring, cracks, inclusions and other harmful defects on the use of the strip without any delamination.
6.5.2 steel surface allows a small amount does not affect the moldability and coating, plating adhesion defect, such as minor scratches, indentation,
Pitting, roll mark and oxidation tint like.
6.5.3 Since the strip with no opportunity to cut the defective portion, thus strip allowed defect delivery, but the defective part can not
More than 6% of the total length of each volume.
7 inspection and testing
7.1 strip appearance was visually inspected.
Size 7.2 steel, shape using the appropriate measurement tool.
7.3 For trimming strip thickness measurement pitch edge at any point of not less than 5mm; for not trimming strip thickness measurement
Points from the edge of not less than 25mm at any point.
7.4 test strip batches, each batch from the same grade steel is not more than 30 tons of the composition.
7.5 each batch of test strip project, the number of tests, sampling methods and test methods shall be in accordance with Table 3.
table 3
Number of test items Test (a) Test Method for Sampling method
Hardness 1 GB/T 230.1
Surface roughness of 1 GB/T 2975 GB/T 2523
7.6 reinspection
For the hardness test, if the test results do not meet a particular standard, from the same batch and then either take double the number of specimens
Retest the failed project. Retest results (including all indicators of the project test required) qualified, then the whole batch together
grid. Retest results (including all indicators of the project test required) even if there is an indicator of failure, then retest failed.
As retest failed, already a test and the test results can not be incompatible single acceptance, but without making a single piece of material batch tests
Piece by piece can resubmit testing and acceptance.
8 packaging, marking and inspection documents
Press Q provisions strip packaging, marking and inspection documents/BQB 400's. For square packaging weight have special requirements, should be
Indicated in the contract.
9 numerical rounding rules
Numerical rounding rules should comply with GB/T 8170's.
