The use of TBT 1979 08CuPVRE steel sheet is still faced with some problems

The blanking of the structural steel plate is first to find 90 degrees, and then use a tape measure and a powder line to draw the cutting range. According to the thickness of the carbon steel plate plus the cutting allowance, drilling is required. For the deep processing of TBT 1979 08CUPVRE steel sheet structural steel sections or profiles: First use a square ruler or a curved ruler to find 90 degrees, and then use a square ruler or a ruler to cut the line and add the cutting margin to the hole.

20 to 26mm thick TBT 1979 08CUPVRE steel sheet product BBN steel supply: 20*3000*5000, 20.5*2370*7000, 21*1960*7950, 22*1800*8000, 22*1500*6000, 22*1500*6050, 22.5*1680*8450, 22*1300*4000, 22*2600*9000, 22*1800*9000, 22.5*2560*7150, 23.5*2560*7150, 25*1460*4000, 23*3000*11980, 23*2480*8450, 23*2650*6000, 24*1560*6200, 25.5*2330*8300, 23*3000*12000, 23.5*2080*8100, 23*2650*6550, 26*3010*8100.

On the morning of March 10th, according to the news conference of the Joint Prevention and Control Mechanism of the State Council, Deputy Director of the Emergency Management Department Shang Yong said that since the outbreak, 20,000 and 172,000 safety guidance groups have been organized nationwide, keeping a close eye on High-risk industries such as coal mines and non-coal mines inspected and guided 223,000 enterprises and rectified 168,000 hidden problems.

The strengthening mechanisms in metals mainly include solid solution strengthening, dislocation strengthening, fine grain strengthening, and second phase (precipitation and dispersion) strengthening. Alloying elements have the most significant strengthening effect on steel in the quenched and tempered state, because it makes full use of all four strengthening mechanisms. Martensite is formed during quenching, and carbides are precipitated during tempering, resulting in a strong second phase strengthening and greatly improving toughness. Therefore, obtaining martensite and tempering it is the most economical and effective comprehensive strengthening method for TBT 1979 08CUPVRE steel sheet.
