What is the hardness of the wear-resistant steel plate?
But not the higher the hardness, the better the wear resistance! The hardness is based wear resistant steel plate excellent wear resistance, but the relationship between the hardness and wear resistance is not proportional to the wear resistance; wear resistant steel plate, mainly because they have hard particles, and soft matrix, generally in the wear process, there will be some shedding substances, these substances will be integrated into the soft matrix that will not cause great harm to the surface; if the matrix hardness is relatively high, shedding of abrasive or other substances, the mutual movement will be mutual lapping, faster damage matrix!
The main application of impact resistant steel plate:All kinds of medium and heavy stamping, drawing, forming, printing, forging mold.The motor of /EI silicon steel sheet stamping die drawing, canned, impact punch, cold forming.Thick cold tie plate drawing die, stainless steel precision punch, cold extrusion, reverse extrusion convex die.
WZB-NM500 is the production of Wugang is more than 450 hardness of HB class can be used welding of high strength wear-resistant steel structure, the manufacturing equipment is suitable for use in high wear, high impact situations, but also can be used as high strength structural steel yield strength more than 700MPa. His hardness can reach about HV1300.
The microhardness of the wear-resisting layer of the wear-resisting steel plate can reach HVl700 ~ 2000, and the surface hardness can reach HRc58 to 62. The wear-resistant layer of the wear-resistant steel plate is mainly made of chromium alloy, and other alloy components such as manganese, molybdenum, niobium and nickel are added. The carbides in the metallographic structure are distributed in a fibrous direction, and the direction of the fiber is perpendicular to the surface.
