hardess of nm500 steel plate with coated surface

Steel Q345R (HIC) is a Q345R pressure vessel plate with hydrogen induced cracking resistance test. Q345R(R-HIC) plate is based on Q345R (HIC) and SSCC test, namely sulfide stress corrosion test. The delivery status of Q345R (HIC) and Q345R Q345R(R-HIC) plate is normalizing, - 30 ℃ impact, level I flaw detection, process reference standard GB713-2014. hardess of NM500 steel plate, Q345R (HIC) and Q345R (R-HIC) plates are smelted by electric furnace + refining outside the furnace. The smelting process is Ca-treated, and should be intrinsically fine-grained steel. The actual grain size is 5 or above.

The boiler steel plate has small strain aging sensitivity, especially in the corresponding working temperature range, a certain value of aging impact energy must be guaranteed;The boiler steel plate has low notch sensitivity, which can prevent steel from cracking in welding, opening, and local stress concentration areas;The hardess of NM500 steel plate, boiler steel plate has good welding performance;The hardess of NM500 steel plate, boiler steel plate has a good microstructure, white spots and cracks are not allowed.

Both the cross rolling method and the extrusion method must first heat the tube blank or ingot, and the steel tube produced is called hot rolling tube. Steel pipes produced by hot working can sometimes be cold worked as required. There are two methods of cold working: one is cold drawing, that is, drawing the hardess of NM500 steel plate steel pipe through the drawing die to make the steel pipe gradually thin and elongate; the other is cold rolling, which is the method of applying the hot rolling mill invented by the menesmann brothers to cold working. The cold working of hardess of NM500 steel plate seamless steel pipe can improve the size accuracy and finish of steel pipe, and improve the mechanical properties of materials.
