Problems solved by technology

Or at least one of Fe-based alloys, Co-based alloys and Ni-based alloys is selected from the powder mixture of matrix metal mixed with VC powder with a particle size of less than 10um. This material has good corrosion resistance and wear resistance. But it contains VC powder with high price, and the preparation process is complicated
[0009] Through the comparison and analysis of the above patents, it can be seen that the stainless steel in the prior art cannot fully meet the current use and manufacturing requirements. The main problem is that the cost of the stainless steel is high due to the high wear resistance, and the low-cost stainless steel has generally poor wear resistance. Therefore, it is necessary to develop a stainless steel material with high wear resistance and low cost

Abstract

The invention relates to the technical field of a coffee maker material, and particularly relates to a high-wear-resisting stainless steel coffee maker material and a preparation method thereof. The high-wear-resisting stainless steel coffee maker material comprises the following elements in percentage by weight: 0.08-0.12% of C, 0.06-0.1% of N, 0.15-0.55% of Si, 0.6-1% of Mn, 11.5-13.5% of Cr, 0.1-0.3% of Ni, 0.6-1% of Mo, 0.2-0.6% of Al, 0.05-0.25% of Zr, 0.01-0.05% of Y, 0.6-1% of Nb, 0.05-0.15% of Ti and the balance of Fe and impurities. The high-wear-resisting stainless steel coffee maker material has relatively high hardness and wear resistance by strictly controlling the content of each element, is low in production cost and also has relatively high strength, toughness, heat resistance, corrosion resistance and excellent combination property.

Description

technical field [0001] The invention relates to the technical field of coffee pot materials, in particular to a high wear-resistant stainless steel coffee pot material and a preparation method thereof. Background technique [0002] A coffee pot is a device for brewing coffee. With the improvement of people's living standards, the scope of use of coffee pots is becoming wider and wider, and there are more and more types of coffee pots, including stainless steel coffee pots, plastic coffee pots, and glass coffee pots. Pots, etc. Stainless steel coffee pots are the main sales types in the market due to their high toughness, strength, wear resistance, heat resistance and corrosion resistance. [0003] Due to the special use environment of coffee pots, stainless steel coffee pots need to be made of stainless steel with high wear resistance, and there are more and more researches on high wear-resistant stainless steel materials.
