摘要

p AN ABRASION RESISTANT STEEL PLATE IS PROVIDED WHICH HAS HIGH HARDNESS UP TO THE PART OF THE MEDIUM THICKNESS THEREFORE THE STEEL PLATE IS 50 MM OR MORE, AND CAN BE MADE UP TO LOW COST. THE ABRASION RESISTANT STEEL PLATE HAS A SPECIFIC CHEMICAL COMPOSITION THAT HAS A DI * OF 120 OR MORE, WHERE DI * IS DEFINED BY THE FOLLOWING FOAcute; RMULA (1): DI * = 33.85x (0.1xC) 0.5x (0.7xSi + 1) x (3.33xMn + 1) x (0.35xCu + 1) x (0.36xNi + 1) x (2.16xCr + 1 ) x (3xMo + 1) x (1.75xV + 1) x (1.5xW + 1),IT HAS A HB1 OF 360 HBW10 / 3000 TO 490 HBW10 / 3000, HB1 IS A BRINELL HARDNESS AT A DEPTH OF 1 MM FROM A SURFACE, HAS A RATIO OF HARDNESS, HB1 / 2 WITH RESPECT TO HB1, OF 75% OR MAacute ; S, HB1 / 2 IS A BRINELL HARDNESS IN A POSITION OF MEDIUM THICKNESS, AND HAS A PLATE THICKNESS OF 50 MM OR MAacute; S. /p
