Difference Between Cold Drawn Steel and Hot Rolled Steel

First, the processing methods are different. Cold drawn steel is used to improve the yield of reinforcement under normal temperature, and also to save steel. The purpose of deformation of reinforcement is achieved when the tensile stress exceeds the yield but is less than the maximum bearing capacity of reinforcement.

Hot rolled steel is made by heating and pressing at high temperature.

Secondly, the application fields are different:

Cold drawn steel: woodworking machinery, ceramic machinery, paper making machinery, glass machinery, food machinery, construction machinery, plastic machinery, textile machinery, jack, hydraulic machine, etc; Electrical product parts: motor shaft, fan shaft, sewing machine shaft, etc; Furniture: especially export metal furniture, such as tea table, chair and outdoor furniture.

Hot rolled steel: metal appliances: garden tools, grill grid, screws, anti-theft locks, etc; Hardware accessories: such as guide rails, machine keys, nuts, screws, round nails, hexagonal nails, octagonal nails and various standard parts of different specifications; Auto, motorcycle parts, etc.
