13MnNiMoR steel plate for medium and low temperature pressure vessels

13MnNiMoR steel plate is a steel plate for medium and low temperature pressure vessels, which is widely used in petroleum, chemical, power station, boiler and other industries. It is used to make reactors, heat exchangers, separators, spherical tanks, oil and gas tanks, liquefied gas tanks, nuclear reactor pressure shells, boiler drums, liquefied petroleum gas cylinders, high pressure water pipes of hydropower stations, turbine casings and other equipment and components.

13MnNiMoR steel plate delivery status:
The steel plate can be delivered in hot rolling, controlled rolling, normalizing, annealing, tempering, normalizing+tempering, tempering and other conditions; The tempering temperature of 13MnNiMoR steel plate shall not be lower than 650℃.

Flaw detection and thickness direction performance of 13MnNiMoR steel plate:
We can produce additional flaw detection requirements and Z15-Z35 tear resistance (thickness direction performance) steel plate, and also provide Z-direction performance steel plate according to ASTM, A770 and other standards.

Production process of 13MnNiMoR steel plate:
Electric furnace smelting → LF/VD furnace refining → ingot casting → ingot cleaning → ingot heating → plate rolling → flaw detection → normalizing → tempering → steel plate grinding → flaw detection → cutting sampling → performance inspection → warehousing

Characteristics of 13MnNiMoR steel plate:
13MnNiMoR steel adopts many new processes, such as multi-element microalloying treatment, liquid steel vacuum treatment, inclusion denaturation treatment, low speed and large reduction rolling of steel plate and controlled rolling and controlled cooling. It has good strength and toughness, good welding performance, good internal quality, good HIC resistance and hydrogen sulfide corrosion resistance, and meets the requirements of low welding crack sensitivity.
