In conventional packaging, transportation, loading By unloading and storage conditions, the supplier shall ensure that from the date of manufacture is completed within six months, the surface of the stainless steel sheet and strip. according to The demand side, the agreement by both parties and specified in the contract, but also may not be coated with oil supply. For non-oiled product handling, Storage and use of rust generated in the process, scratches and friction marks and other defects, the supplier shall not bear the responsibility for product quality. Note. usually the product inspection document issued by the date fixed for the completion date of manufacture. 6.4 Mechanical Properties 6.4.1 for guarantees from the date of manufacture is completed within six months, the mechanical properties of the steel sheet and strip shall comply with the requirements of Table 5. 6.4.2 When the steel sheet and strip specified parts supplier, the supply and demand sides can agree on a mechanical part of the process to meet the demand Performance range as the acceptance reference, this time, the mechanical properties specified in Table 5 will no longer be used as the basis for delivery. 6.4.3 due to aging, the mechanical properties of the steel sheet and strip with the extension of storage time will be deteriorated, such as yield strength And the rise of the tensile strength, percentage elongation decreased formability deterioration appears tensile strain marks, etc., it is recommended to do Early use. table 5 Trademark Tensile tests a, b 180 ° bending test (B≥20mm) c Bend Core diameter Hardness values d HRB Yield Strength MPa tensile strength MPa The Elongation A80mm not less than B320LW ≥210 320 ~ 410 28 0a - B360LW ≥215 360 ~ 450 26 0a - B440QZ ≥280 440 ~ 540 15 1a - BMCP84 - - - - ≥84 B350JL 250 ~ 350 350 ~ 500 20 1a - St12G ≤280 295 ~ 430 28 - - St14J 180 ~ 220 280 ~ 370 39 - - Stl2Q 215 ~ 285 320 ~ 390 32 - - Stl2Q1 245 ~ 300 370 ~ 430 28 0.5a - When using RP0.2 yield a clear no, otherwise use ReL. b specimen of GB/sample, a sample of 228 T P6 direction to landscape. ca represents the thickness of the sample to the longitudinal direction of the sample. d hardness is the average of three experiments. 6.5 For grades BMCP84 strip, usually in the chilled state and oiled after delivery, the strip surface should be smooth, surface Average roughness Ra≤O.70μm. As for the order to ensure, without performing average surface roughness test. 6.6 surface quality Steel sheet and strip surface 6.6.1 There must be no holes, surface cracks, and other laminated on the use of harmful defects. 6.6.2 Each steel strip surface quality level characteristics and should meet the requirements in Table 6. 6.6.3 For steel, because there is no opportunity to cut with the defective portion, thus strip allowed defect delivery, but flawed Shall not exceed 6% of the total length of each volume. Table 6 Level code feature More advanced surface finishing FB surface allows a small amount does not affect the formability and coating, plating adhesion defect, such as minor scratches, indentation, pitting, roll mark and oxidation tint like. FC advanced surface finishing products in two faces better side no visible obvious defect, the other side should at least meet the requirements of the FB. Premium surface finishing FD products two faces in a better side should not affect the quality or appearance after painting after plating appearance quality defect, the other side should at least reach FB requirements. 6.7 surface structure Surface structure when Pock (D) by the average roughness Ra 0.6μm < Ra≤1.9μm control, surface structure shiny surface (B), The average roughness Ra press Ra≤0.9μm control.7 inspection and testing7.1 steel sheet and strip appearance was visually inspected. Size 7.2 steel sheet and strip, shape should be appropriate measurement tool. 7.3 tensile test shall be in accordance with GB/T 228.1 Method B. In order to improve the reproducibility of the measurement results, we recommend using the beam displacement Control method, the yield strength measured rate of 5% Lc/min, as measured parallel to the tensile rate (Lc of the sample 40% Lc/min length). 7.4 Acceptance steel sheet and strip shall grant each inspection lot shall be not more than 30 tons of the same grade, same size, same processing condition, Steel sheet and strip components. For weighing more than 30 tons of steel, each composed of a coil inspection lot. 7.5 each batch of steel sheet and strip the test items, the number of samples, sampling methods, test methods shall be in accordance with Table 7. 7.6 The supplier may use different tests and test methods for acceptance testing. Event of a dispute, should present technical conditions of Regulation Set of inspection and testing methods and related technical requirements for testing.

Retest results (including the required test project All indicators) qualified, then the whole batch is qualified. Retest results (including all indicators of the project test required) even if there is a finger Standard fail, then retest failed. As retest failed, already a test and the test results of a single piece of incompatibility can not acceptance, but Batch material without making a single piece by piece test can resubmit testing and acceptance. 8 packaging, marking and inspection documents Steel sheet and strip packaging, marking and inspection documents shall comply with Q/BQB 400's. For a party to have special packaging weight Requirements should be specified in the contract.9 numerical rounding rulesNumerical rounding rules should comply with GB/T 8170's. ......Tips & Frequently Asked Questions:Question 1: How long will the true-PDF of BZJ463-2014_English be delivered?Answer: Upon your order, we will start to translate BZJ463-2014_English as soon as possible, and keep you informed of the progress.
