The delamination problem of a242 type 1 steel grating

Compared with 12CrMoV steel, a242 type 1 steel grating, 12Cr1MoVR pressure vessel steel has higher oxidation resistance and heat strength. The creep limit of this steel is very close to the endurance strength value, and it has high plasticity under the condition of long-term stretching; the steel has good manufacturability and weldability, but it needs to be preheated to 300 ° C before welding, and the stress needs to be removed after welding deal with.

The development a242 type 1 steel grating of the company comes from the resource advantage, service advantage, logistics advantage and brand advantage established over the years, and it is also inseparable from the full support of new and old customers. We will uphold the support of all sectors of society, actively provide users with a242 type 1 steel grating high-quality and efficient services, work together for win-win, and create a better tomorrow!

Hot rolled a242 type 1 steel grating steel coil and plates are among our main products. Hot rolling can significantly reduce energy consumption and cost. During hot rolling, the metal has high plasticity and low deformation resistance, which greatly reduces the energy consumption of metal deformation. Hot rolling can improve the a242 type 1 steel grating processing properties of metals and alloys, that is, the coarse grains in the casting state are broken, cracks are obviously healed, casting defects are reduced or eliminated, the as cast structure is transformed into deformed structure, and the processing properties of alloys are improved.

When the steel plate containing molybdenum only is at high temperature for a long time, the carbon will aggregate into graphite and precipitate, which will worsen the performance. To eliminate this tendency, chromium is often added to the a242 type 1 steel grating, steel plate at the same time. When chromium is added to the steel plate, the heat strength, high temperature oxidation resistance and corrosion resistance can also be improved.

As one of the large professional metallurgical manufacturers in China, the strength of the brand, quality assurance, professional after-sales. Every day we are making unremitting efforts to challenge higher quality a242 type 1 steel grating products and more satisfactory services. Customer demand is our pursuit, and win customer satisfaction with quality. BBN after-sales team is responsible to solve the problem of technical support and quality, service complaints.
