This creep limit of the steel with the persistent intensity value is very close to, and having a high plasticity in the case of persistent stretched; process with good weldability of the steel, but before welding was preheated to 300 ° C, required after welding stress-relief processing. High-pressure, high pressure, subcritical power station boiler superheater header and main steam conduit widely used kinds of steel. 580 ℃ still has a high thermal strength and anti-oxidant properties, have higher durable plastic. The production process is relatively simple, and good weldability, but normalizing cooling rate sensitive. 580 ℃ long-term use will produce pearlite spheroidization. This steel is mainly used for the manufacture of high voltage equipment temperature does not exceed 570 ~ 585 ℃ superheated steel pipe, conduit, snake-like tube and forgings after normalizing and tempering. ① steel at the beginning of the two numbers indicate the carbon content of the steel, said the average carbon content of the very few, such as 40Cr, 25Cr2MoVA alloy pipe ② steel major alloying elements, in addition to individual micro-alloying elements, generally a few percent said. When the average alloy content of <1.5%, steel generally marked element symbols, rather than marked content prone to cause confusion, but in exceptional circumstances, can also be marked with the number "1" in the element symbols, such as steel, No. the the "12CrMoV" and "12Cr1MoV", the former of chromium content of 0.4-0.6%, the latter is 0.9-1.2%, and the remaining components are all the same. When the average content of alloying elements ≥ 1.5% ≥ 2.5% ≥ 3.5% ... behind the element symbols should be marked content, corresponding to 2,3,4 ... and so on. For example, 18Cr2Ni4WA. ③ steel vanadium V, titanium Ti, AL aluminum, boron B, and rare earth RE, alloying elements, are micro-alloying elements, although the content is very low, should remain in the steel marked. E.g. 20MnVB steel. Vanadium 0.07-0.12% and 0.001-0.005% boron. ④ High quality steel in the steel and finally add the "A", to distinguish it from the general high quality steel. ⑤ special purpose alloy structural steel, steel dubbed (or suffix) on behalf of the symbols of the use of the steel. Such as riveting Lo dedicated 30CrMnSi steel, steel to ML30CrMnSi. Foreign grades 16Mo3 12Cr1MoV corresponding welding with other materials, first preheated, and after the completion of welding, the weld should incubated for about 30 minutes 16Mo3 steel manganese is also important alloying element in the steel and is also an important hardenability elements , it has a great influence in the toughness of the weld metal. 16Mo3 plate when the Mn content is 3% and then is very brittle; 16Mo3 plate when the Mn content = 0.6% to 1.8%, the weld metal has a high strength and toughness. 12Cr1MoV 6 * 1800 * 8000 0.712 + back two flaw 8 * 1800 * 8000 0.938 n + back to the two testing 10 * 2000 * 8000 1.3 + back 2 testing 10 * 2000 * 10000 1.625 + back to the two testing 12 * 2000 * 8000 1.551 + back 2 testing 12 * 2000 * 8000 1.551 + back two testing 18 * 2300 * 10100 3.364 + Back 2 testing 14 * 2000 * 10000 2.253 + back to the two testing 14 * 2200 * 10000 2.841 + back to the two testing 20 * 2150 * 14300 4.936 + back two testing 40 * 1950 * 9400 5.756 + Back 2 testing 65 * 1830 * 9600 8.964 + Back 2 testing 60 * 2290 * 10750 is 11.711 + back 2 testing set tie all kinds of futures spot, short delivery time, welcome to discuss!
