Introduction of 08Ni3DR grade of steel plate for ultra-low temperature pressure vessel

08Ni3DR steel plate is mainly used in the manufacture of ultra-low temperature equipment such as large cryogenic storage tanks and pressure vessels in the chemical field Previously, the 08Ni3DR steel plate with an impact temperature of -100 °C developed by Wugang has passed the review organized by the National Boiler and Container Standards Committee, with a review thickness of 100mm, which is at the leading level
in China. The steel plate is delivered in a normalized (allowing accelerated cooling) plus tempering state, or offline quenching plus tempering state. The tempering temperature is not less than 620 °C, and the steel plate with a thickness of no more than 25mm can be delivered in a normalized state.
08Ni3DR Executive standard: GB3531-2014
08Ni3DR impact temperature: -101°C impact
In order to meet the domestic market demand and improve the market share of products in the high-end market, Wugang has developed ultra-thick 08Ni3DR steel plates. The successful trial production of 150mm thick 08Ni3DR steel plate, after the comprehensive performance inspection of professional authorities, is fully qualified. Wugang Company has successfully trial-produced an ultra-low temperature 08Ni3DR steel plate with a thickness of 150mm in China, and the product flaw detection is in line with the national standard level 1 and has excellent performance. So far, the production of ultra-low temperature 08Ni3DR steel plate has become a reality in Wugang, which can provide a complete set of ultra-low temperature steel plates for the manufacturing of a complete set of low temperature equipment in the chemical field.

08Ni3DR is widely used in petroleum, chemical industry, power station, boiler and other occupations, and is used to manufacture reactors, heat exchangers, separators, spherical tanks, gasless tanks, liquefied gas tanks, nuclear reactor pressure shells, boiler steam drums, liquefied petroleum gas cylinders, high-pressure water pipes of hydropower stations, water wheel vortex shells and other equipment and components.
At present, the company has completed more than 780 tons of 08Ni3DR steel plates, with complete specifications and can be processed and cut according to the drawings. In addition, according to the customer's technical needs to arrange futures rolling business, the price is low, the delivery cycle is short, if there is a demand, you can consult the company's business manager.
