13MnNiMoR What material is it ,13MnNiMoR Steel plates for medium and low temperature pressure vessels

 

13MnNiMoR It is a kind of steel plate for medium and low temperature pressure vessels

perform GB713-2014 standard

13MnNiMoR Delivery status ： Normalize + Temper

Wuyang Iron and steel sun fan

13MnNiMoR Production specifications ： The thickness of the 8mm-300mm, Width 1500mm-4020mm, length 3000mm-18000mm.

13MnNiMoR The steel is treated by multi-element microalloying 、 Vacuum treatment of molten steel 、 Many new processes, such as inclusion modification treatment, low-speed heavy reduction rolling and controlled rolling and cooling of steel plate 、 It has good strength and toughness 、 Good welding performance 、 Good internal quality 、 Good resistance HIC And hydrogen sulfide corrosion resistance , Meet the requirements of low welding crack sensitivity .
According to the new regulations ：13mnnimor The tempering temperature of shall not be lower than 620 degree . Old brand 13MnNiCrNbg and 13MnNiMoNbR No longer use .
