How to protect a516 grade 70 flange from crack

Our company's a516 grade 70 flange power boilers, heating furnaces of double bars, double high lines and medium and thick plates all adopt heat storage technology, which can fully use blast furnace gas; the ladle baking, Maerz active lime kiln and medium and thick plate heat treatment furnace all burn converter gas, which can improve the a516 grade 70 flange utilization rate of secondary energy and realize negative energy steelmaking in steelmaking process.

The difference between q345 and q235 steel a516 grade 70 flange
The lower limit of yield strength of Q345 is 345MPa (the actual meaning of Q is the Chinese character ""qu"", and the standard value behind means the lower limit of yield strength). Q235 steel is used for metal structural parts, nitrided or cyanidized parts with low core compressive strength requirements, support rods, crankshafts, crane hooks, couplers, bolts and nuts, sleeve specifications, shafts and weldments.

Wear resistant steel plate has high wear resistance and good impact performance. It can be cut, bent, welded, etc. This material a516 grade 70 flange can be connected with other structures by welding, plug welding, bolt connection, etc. Wear resistant steel plate has the advantages of saving time and convenience in the process of maintenance. It is widely used in metallurgy, coal, cement, electric power, mining, building materials and other industries. Compared with other materials, wear resistant steel plate has a high cost performance, and has been favored by more and more industries.

The principle of stainless steel, the corrosion resistance of a516 grade 70 flange, stainless steel depends on chromium, it depends on a very thin, solid and fine stable chromium rich oxide film (protective film) formed on its surface, to prevent oxygen atoms from continuing to infiltrate and oxidize, so as to obtain the corrosion resistance.
