How to correct the tortuosity of hot rolled 09CuPTiRE-B

ArcelorMittal USA said hot rolled 09CuPTiRE-B it was planning to work with the United Steelworkers union "to minimize the impact on its employees. The company will continue to communicate with its customers to understand the market impact of the outbreak of covid-19, which may require additional capacity optimization to maintain a balance between supply and demand.

The technology center has always been focusing on application research, improving market realization and scientific and technological contribution rate; taking user demand as the goal, highlighting the personalized development of products; taking the joint development of industry, University and research, and technology integration as the means, improving the starting point and level of innovation, and realizing the breakthrough of core technology; taking advanced research as the guide, pursuing the leap of technological development; taking system and mechanism innovation as the driving force, Promote and realize the working concept of technological innovation.

42Cr2Mo steel is an ultra-high strength steel. The steel has high strength and toughness, good hardenability, no obvious temper brittleness, and small deformation during quenching. After quenching and tempering, 42Cr2Mo alloy has a higher fatigue limit and resistance to multiple impacts. Good impact toughness at low temperature, high creep strength and enduring strength at high temperature. The steel hot rolled 09CuPTiRE-B usually adopts surface quenching after quenching and tempering as the heat treatment plan.

A36 plates technical parameters, A36 ms steel sheets datasheet: A36 steel consists of carbon 0.25% max., phosphorus 0.040% max., sulphuric 0.050% max., silicon 0.40% max. and copper 0.20% max.

Modulus of elasticity (Young’s modulus): 200 GPa (29×103 ksi). Shear modulus: 79.3 GPa (11.5×103 ksi). The density of hot rolled 09CuPTiRE-B, A36 plates is 7.85g/cm3.

BBN steel had provided Grind plates for more than 15 years for widely applied in equipment, Engineer machinery etc. In 2018, one of our India customer visit our hot rolled 09CuPTiRE-B office and work shop to discuss Q235B Grind plate technical request, they have strict surface and thickness tolerance, and they also request UT and MT for testing. As a result, they purchase hot rolled 09CuPTiRE-B 179 tons as trial order for first cooperation. And have good comment on our quality. Till now, we keep exporting around 100 tons per month as regularly.

Our steel products are widely used in petroleum and natural gas, chemical industry, shipbuilding, automobile manufacturing, power generation, mining, and other industries. The products hot rolled 09CuPTiRE-B are sold in more than 20 provinces, cities and all over the world. The company has strong technical force, complete production equipment, advanced production technology, perfect testing methods, and high-quality products.
