2 1/4 inch plate hardox 400 hot wear stock
"As Covid 19 spreads around the world, all unnecessary businesses and factories have been closed in Italy this week. South Korea's POSCO, the world's fifth-largest steelmaker, announced on March 24th that it would close its HARDOX 400 hot wear wire-processing centre near the northern Italian city of Verona from Thursday March 26th until April 3rd. POSCO has already closed two wire-processing centres in Delhi and Pune. Two wire processing centers in Malaysia and Thailand also announced last week that they will be closed until March 31."
When pouring the steel with high Mn content, some manganese oxide should be added in the initial slag in advance to prevent the occurrence of the above events. In order to prevent the longitudinal crack of wear-resistant steel plate, HARDOX 400 hot wear, some measures are often taken to reduce the content of P, S and Se in NM360 wear-resistant steel plate. Strictly control the liquid level fluctuation of the crystallizer; reasonably control the negative sliding time; try to increase the temperature difference of the water in the crystallizer as much as possible.
20# seamless steel pipe chemical composition: C: 0.07-0.23, Si: 0.17-0.37, Mn: 0.35-0.65, Cr: 0.25, Ni: 0.30, Cu: 0.25. 20# seamless steel pipe mechanical properties: recommended heat treatment temperature: 910℃, tensile strength: 410 MPa, yield strength: 245 MPa, elongation: 25%, impact energy is not required. 20# seamless steel pipe hardness is higher than 10# seamless steel pipe. HARDOX 400 hot wear, 20# seamless steel pipe has good weldability, no temper brittleness, and its machinability can be improved by water quenching. 20# seamless steel pipe can be used to make welded components, as well as parts with small load after forging, hot stamping and cutting.
