Shandong Xinhe Co., Ltd. is committed to spot, processing, sales as one of the steel enterprises. The company mainly produces and sells various specifications of NM360 wear-resisting plate, NM400 wear-resisting plate, NM450 wear-resisting plate, NM500 wear-resisting plate, NM550 wear-resisting plate, NM600 wear-resisting plate, high strength plate, weathering steel plate, alloy steel plate, Baosteel Mn13 steel plate, shelf tube, steel ‘seamless steel tube’ 20# ’45# and so on. And established solid business relations with both large steel mills.
The microhardness of wear-resisting layer carbide of wear-resisting steel plate can reach above HVl700 ~ 2000, and the surface hardness can reach HRc58 ~ 62. The wear-resisting layer of wear-resisting steel plate is mainly chromium alloy, and manganese, molybdenum, niobium, nickel and other alloy components are also added. The carbide in the metallographic structure is fibrous distribution, and the fiber direction is vertical to the surface.
But not the hardness is higher, wear resistance is better! Hardness is the basis of good wear resistance of wear-resisting steel plate, but the relationship between hardness and wear resistance is not proportional. Wear-resisting steel plate is wear-resisting, mainly because they have hard particles, and there are soft matrix, generally in the process of wear, there will be some material off, these substances will be integrated into the soft matrix, will not cause great damage to the surface; If the hardness of the matrix is also relatively high, the abrasive or other substances that fall off will grind each other in the mutual movement, and the matrix will be destroyed faster!
NM500 steel plate is a kind of high strength wear-resisting plate, mainly to help the occasions or parts of wear-resisting to provide protection, so that the equipment life is longer, reduce the maintenance shutdown brought by maintenance, corresponding to reduce the investment of capital.
