Abstract

The invention provides a low-cost cold-rolled high-strength steel for tool cabinets. The chemical composition and weight percentage of the cold-rolled high-strength steel are: C: 0.07%-0.1%, Si≤0.03%, Mn: 0.2%-0.4%, P≤0.025%, S≤0.03%, Al: 0.03%~0.05%, the balance is Fe and unavoidable trace elements. The present invention obtains a cold-rolled high-strength steel for tool cabinets with higher strength and better plasticity without deliberately adding various alloy elements, greatly reduces production costs, and improves the processing performance and use of tool cabinets. safety performance.

Description

Technical field [0001] The present invention belongs to the field of steel production and manufacturing, specifically relates to a low-cost tool cabinet with cold-rolled high-strength steel. Background [0002] Tool cabinet according to the use of the place of classification can be divided into factory workshop tool cabinet, school special tool cabinet and household tool cabinet, mainly used for tools, materials, parts, documents, etc. storage, the current world used in the mainstream materials for iron plate, hot-rolled steel plate, cold-rolled steel plate and stainless steel plate four. The iron plate tool cabinet material is cheap, but the performance is unstable, the sealing is poor, and it is easy to rust; The comprehensive performance of hot-rolled steel plate tool cabinet is better than that of iron plate, but there are also shortcomings of structural instability and easy deformation; Cold-rolled steel plate tool cabinet has good sealing, is not susceptible to moisture, an...
