Abstract

The invention relates to environment-friendly 310 stainless steel powder feed and a preparing method of the environment-friendly 310 stainless steel powder feed. The environment-friendly 310 stainlesssteel powder feed comprises 310 stainless steel powder and a forming agent, and the 310 stainless steel powder and the forming agent are mixed according to the weight ratio of 100:2-100:5; and the granularity of the 310 stainless steel powder is 500 meshes, the tap density ranges from 4.5 g / cm<3> to 4.8 g / cm<3>, a hard alloy ball is an auxiliary material used during material mixing of a planetaryball mill and accounts for 30%-50% of the total weight, and the diameter of the hard alloy ball ranges from 5 mm to 10 mm. The environment-friendly 310 stainless steel powder feed and the preparing method of the environment-friendly 310 stainless steel powder feed have the beneficial effects that due to the fact that 310 stainless steel metal powder pressing forming feed and a preparing method are invented, the defects that traditional 310 stainless steel is hard to machine, long in machining period and high in machining cost are changed, the manufacturing and machining cost of complex 310 stainless steel parts is greatly reduced, the national summon is responded, and the domestic manufacturing industry technological innovation production level is improved.
