P355GH belongs to the medium pressure boiler plate. It is a kind of steel plate used for European pressure vessels.
P355GH execution standards:
The executive standard is EN10028 (European standard for steel plate for pressure vessels).
P355GH main uses:
The European standard EN10028-2:2003 is used for the high temperature performance steel plate for the manufacture of container equipment. The tensile strength of Rm360-630MPa, yield strength ReH:235-355MPa, elongation of the minimum 20-24%, KV J C -20 minimum impact degrees 0 degrees C degrees C--27J, --34J, +20 ~ C --40J: European standard EN10028-2:2003 product thickness of 8-260mm. status: +N +NT normalizing and tempering, normalizing, quenching and tempering +QT.
P355GH acceptance criteria:
The acceptance test must take into account all the heat treatment that the parts are subjected to during the process of production. If the Contractor does not require the use of M122, the acceptance test must comply with the requirements of this section. In this case, do not have to test the condition of delivery, but the sample must be separately simulated stress relief heat treatment furnace in laboratory. The requirements relating to the heat treatment conditions must follow the requirements of the M151. The provisions of sampling conditions, test methods and test results of the value and only after heat treatment of the same sample delivery.
The minimum tensile strength at 300 C is as follows:
For P235GH steel: 324MPa;
For P265GH steel: 369MPa;
For P295GH steel: 423MPa;
For P355GH steel: 459MPa.
P355GH high temperature tensile test:
High temperature tensile test elongation as reference recording. The fracture absorption of the impact test at - 20 C and - 40 C should be in accordance with the requirements of table I in the appendix. §8.6 必须按AFNOR 标准NF A04—305 进行超声波检验： ——对于1 级设备用钢板：必须按照该标准中扫描图C 级准则，只对厚度 最小为12mm 的零件进行检验。 In addition, as stated in the standard 5.2.2, a same test must be carried out in the welding area with the edge of the steel plate. For the 2 stage equipment, the steel plate is used. According to the standard diagram and the B standard, only the parts with the minimum thickness of 30mm are tested.
For the 3 stage equipment used steel plate: do not ask for ultrasonic inspection. Section 9.1 of 1 grade and 2 grade equipment for steel plate, regardless of how the parts delivery status,
P355GH technology requirements:
When the equipment is specified, the following additional tests must be carried out:
1) the analysis of product composition;
2) tensile test at 300 centigrade temperature;
3) bending test at room temperature;
4) 4) - impact test at 20 C or - 40 C.
P355GH finished product analysis:
Only 1 and 2 grade equipment used for this analysis.
2) high temperature tensile tests are carried out only when the equipment specification or other contract documents are stipulated. The test temperature should be stipulated in the technical specification of the equipment. For the 1 stage steel plate, the inspection should be carried out systematically.
3) the bending test should be carried out systematically.
4) - impact tests at 20 C or - 40 C are carried out only when the equipment specification or other contract documents are stipulated.
9.4 in addition, the distance of the end of the heat treatment at the center line of the sample is at least equal to the thickness of the steel plate. 1) the center line of the impact specimen must be perpendicular to the final rolling direction. The bottom busbar of the notch of the sample must be perpendicular to the rolling surface.
According to the sample of NF EN 10028 - 1, the sample description of the KV sample is changed as follows:
For the 1, 2 and 3 grade equipment used for steel plate, 0 C, 20 C and - 40 centigrade test KV sample requirements for the following:
For a steel plate with a thickness less than 30mm, the sampling site is close to the rolling surface.
For steel plates with a thickness greater than 30mm, 3 specimens are intercepted on the adjacent rolling surface, and the other 3 are specified as follows:
When the thickness is 31~50mm: the center of the thickness of the finished product;
When the thickness is 51~80mm, the thickness of the finished product is 1/3.
When the thickness exceeds 80mm, the thickness of the finished product is 1/4.
P355GH bending test:
2) for the bending test, the size of the sample should be in accordance with the provisions of NF A03 - 157. The thickness of the specimen is usually the thickness of the steel plate. But when the thickness of the plate is more than 30mm, the sample can be thinned to 30mm. In this case, the processing is carried out on a rolling surface of the steel plate, and the other surface is maintained as the outer surface of the bending test. The bending test is carried out on two parallel roller seats, and the thickness of the diameter or compensator is given in the Appendix 2 to the thickness of the steel and sample thickness "a" (unit: mm). The outer surface of the curved surface should be cracked, tearing or bubbling. Test methods of 9.5 test items and use must comply with MC1000. The bending test should be carried out according to the standard of NF A03 - 157.
