Zusammenfassung:	The invention relates to an alloy powder for laser cladding, which comprises 0.05-0.2% of C, 1.0-1.5% of Si, 0.4-0.8% of Mn, 15.0-15.8% of Cr, 4.0-4.5% of Ni and the balance of Fe and unavoidable impurities, wherein the content of all the elements is expressed by weight percent. A mining hydraulic support stand column formed by cladding the alloy powder for laser cladding has good forming property and does not easily have crack after being cladded; furthermore, the mining hydraulic support stand column is good in four combination properties including surface hardness, service life, bonding strength between a cladding layer and a metallic matrix as well as salt spray resistance; and the content of Ni is lower, so that the cost is low.
