specific Embodiment

[0041] Specific examples of heat treatment process of the present invention are as follows:

[0042] group Normalizing temperature (℃) Normalizing time (h) Quenching temperature (℃) Quenching time (h) Tempering temperature (℃) Tempering time (h) Example I 820 0.5 860 1 500 4 Example II 870 1 910 2 600 5 Example III 920 1.5 960 3 700 6

[0043] After heat treatment under the above conditions, the samples were subjected to metallographic microstructure observation, yield strength, tensile strength, and elongation testing and analysis. Figure 5 It is metallographic microstructure under normalizing condition at 870℃, Figure 6 It is the metallographic microstructure under the condition of "normalizing at 870°C + quenching at 860°C + tempering at 500°C", Figure 7 It is the metallographic microstructure under the condition of "normalizing at 870°C + quenching at 910°C + tempering at 600°C".

Abstract

The invention relates to an alloy material and a method for manufacturing a forklift beam by use of the same. The alloy material comprises the following components in percentage by weight: 0.16-0.25% of carbon, 0.8-1.4% of manganese, 0.3-0.6% of silicon, 0.2-0.8% of chromium and the balance of iron. The manufacturing method adopts investment casting, wherein a wax pattern of the investment comprises the following components in parts by weight: 50-70 parts of paraffin, 15-40 parts of polymerized rosin, 5-15 parts of EVA (ethylene-vinyl acetate) and 5-10 parts of lignite wax. The yield strength of a forklift beam manufactured from the alloy material provided by the invention is greater than 620MPa, the tensile strength is over 750MPa, the material elongation reaches 20%, and the hardness exceeds 200HBW; and moreover, the internal texture of the material reaches the first level, and the material has good manufacturability and can completely replace the existing materials such as Q235A steel and the like.
