The salesman of the company is familiar with all aspects of knowledge. Understand the company profile: group, company profile, various honor certification, enterprise's functional strength and other advantages analysis. Know the main product brand types and specifications of the company, and know the special knowledge of the product (production process and advantages of the product, simple identification method of product quality, etc.)
S355NL normalized steel has different impact energy requirement for impact tests at different temperature environment. S355NL plate shall be done impacting test in longitudinal direction under -50℃ with the minimum energy 27J. When customers request done charpy_V notch test under -20℃,then the impacting energy shall be above 47J. For the transverse direction,the engery shall be above 16J under the temperature -50℃. The BV DH40 oil carrier steel, steel Grade S355NL making process shall according to EN10025-1.
BV DH40 oil carrier steel, 12Cr1MoV steel is alloy structure steels, and it is usually produced into 12Cr1MoV steel coil, 12Cr1MoV steel sheet, 12Cr1MoV steel plate, 12Cr1MoV steel bar, etc. 12Cr1MoV steel is composed of Carbon, Silicon, Manganese, Chrome, Molybdenum and so on chemical elements. Amng them, the C content is 0.08-0.15, Si 0.17-0.37, Mn 0.40-0.70, Cr 0.90-1.20, Mo 0.25-0.35. The tensile strength of 12Cr1MoV steel is not lower than 490 Mpa, and yield strength is not lower than 245 Mpa.
Boiler steel refers to the special steel used to manufacture pressure components of steam boilers, such as steam drums. The boiler steel mainly means boiler steel plates and seamless boiler steel pipes. Boiler components not only bear pressure loads but are also heated by direct fire, so the requirements on the chemical composition and mechanical properties of boiler steel, BV DH40 oil carrier steel are strict. In the chemical composition of boiler steel, BV DH40 oil carrier steel, sulfur and phosphorus are strictly controlled. Tensile strength, yield point, elongation, impact energy value and 180 ° cold bending are required to be tested in boiler steel mechanical properties. In addition, strain aging impact test is also required for boiler steel. The quality control of boiler steel is slightly higher than that of pressure vessel steel.
