09CuPCrNi-B steel heat treatment delivered to Japan

For the team, cooperation is the core idea of daily work, and the core of common cooperation is resource sharing. With a perfect resource sharing mechanism, the whole team can be called a unity spirit.A good team lies in the ability to transfer resources, knowledge and information in time among team members in order to achieve the common goals of the team. So that we can share experiences and lessons."

After quenching and tempering, 40Cr alloy steel plate and 09CUPCRNI-B steel heat treatment sheet have good comprehensive mechanical properties, good low temperature impact toughness and low notch sensitivity. The hardenability of steel 09CUPCRNI-B steel heat treatment is good. It can be hardened to Ф28 ～ 60mm during water quenching and Ф15 ～ 40mm during oil quenching. In addition to quenching and tempering, this steel is also suitable for cyanidation and induction hardening. The cutting performance is better. When the hardness is HB174 ～ 229, the relative cutting workability is 60%. 40Cr alloy steel is suitable for making medium-sized plastic molds.

The allowable working temperature of boiler steel plate is generally below 475 ℃, which can't meet the needs of high temperature working condition. Chromium molybdenum steel is one of the common steels for 09CUPCRNI-B steel heat treatment pressure vessels, which is widely used in various hydrogenation units and reforming units in oil refining and chemical industry. Therefore, on the basis of common 09CUPCRNI-B steel heat treatment carbon steel, alloy elements such as Cr Mo V are added, which has excellent hydrogen corrosion resistance and good high temperature strength, It is the material of high temperature and high pressure vessel shell and head.

Good news: The largest steel importer in Nigeria ordered 4068 tons API 5L X52Q PSL2 3LPE seamless pipes and also ordered 8 pcs 42699.6 m³big diameter Crude oil storage doom roof tank in A537CL2 steel grade. In Sep 2019, This Nigeria client visited our company and factory, they were very satisfied with our company's quality control,production capacity and service. We also have reached a agreement for Phase II Project, It is also with another 10,000 tons APl 5L X52Q PSL2 3LPE seamless pipes.
