2.2.4F, Y state of each monitoring of the material, the household army and in the same price, provide the sample after heat treatment, the main temperature measured data, do the heart level according to the disassembly. The test treatment system is: heating in the dust gas production 720+15 seven, keep 202, space into slow cooling and follow.
2.3 Star record organization
The rod after the fire is the micro-area of the non-product organization. Unless there is a need for coordination, the microscopic matrix is too large, and the return cannot be guaranteed.
2.4 Surface contamination
The material surface should be free of any high oxygen content, such as layers or other surface contamination. The surface of the material should not be less than 1.Gm, and the separation is allowed in the area of the text.
2.5 Surface quality
2.5.1 The surface of the plate is smooth, and no chemical reaction is allowed, but the product is full of water. 2.5.2 The plate is not allowed to have a large cost, cost, size, width, etc. 2.5.3 The plate is allowed to have a part of the product, and the tolerance does not exceed half of the order. 2.6. The product shall be free of defects such as corrosion, etc., but the minimum source should be guaranteed. The thickness of the plate after cleaning shall be small. 2.5.5 If the customer has special requirements, the supplier can purchase the product after the supplier meets the requirements. 2.6 Non-destructive testing
Day! The requirements and requirements are clear in the body: when the plate is tested by ultrasonic wave: the supplier and the buyer must confirm the requirements in the standard. 2. The supplier and the buyer must confirm the requirements in the standard. 3.1 Chemical composition arbitration analysis method
