Problems solved by technology

To sum up, it is difficult for ordinary ferrous alloy hooks to fully meet the performance requirements of the hook. Therefore, stainless steel hangers have emerged as the times require. However, the current stainless steel hooks still have insufficient strength and cannot be fully promoted and used.

Abstract

The invention discloses a high-performance stainless steel hook which is manufactured through a powder metallurgy process. The hook comprise, by weight, 7% to 12% of nickel powder, 5% to 10% of chromium powder, 5% to 15% of manganese powder, 3% to 8% of molybdenum powder, 2% to 6% of silicon powder, 4% to 10% of refractory metal carbides, 4% to 85 of plasticizer and the balance being iron powder, wherein the refractory metal carbides are WC or TiC powder. According to the high-performance stainless steel hook, the preparation of components is reasonable, the preparation technology is simple and convenient, and the hook has excellent usage performances on aspects of strength, abrasive resistance, corrosion resistance and the like, so that the usage of the hook is safe and reliable and the application is wide.

Description

Technical field [0001] The invention relates to a stainless steel hook, in particular to a high-performance stainless steel hook with high strength, outstanding wear resistance and corrosion resistance, and belongs to the technical field of stainless steel products. Background technique [0002] Spreader is a device for lifting heavy objects in hoisting machinery. The most commonly used spreader for lifting a piece of article is a hook, and its related accessories include lifting rings, lifting suction cups, clamps and forks. Among them, lifting suction cups, clamps and forks are used together on the crane, which can be used as a special spreader for a long time, and can also be used as an auxiliary spreader for temporary use on the hook to improve work efficiency. The spreader for grabbing bulk materials is generally a grab with open and closing jaws, and electromagnetic chucks can also be used to pick up magnetically conductive materials such as metal chips; the spreaders for l...
