High Quality Cold Rolled Steel Coil Galvanized Steel

High Quality Cold Rolled Steel Coil Galvanized Steel is steel produced by cold rolling.Cold rolling is to further roll No.1 steel plate to the target thickness at room temperature.Compared with hot rolled steel plate, High Quality Cold Rolled Steel Coil Galvanized Steel thickness is more accurate, and High Quality Cold Rolled Steel Coil Galvanized Steel surface is smooth and beautiful, but also has a variety of superior mechanical properties, especially in processing properties.Because the original High Quality Cold Rolled Steel Coil Galvanized Steel is brittle and hard, it is not suitable for processing. Therefore, High Quality Cold Rolled Steel Coil Galvanized Steel is usually delivered to the customer after annealing, pickling and surface leveling.The maximum thickness of cold rolling is 0.1-8.0mm, such as the thickness of most High Quality Cold Rolled Steel Coil Galvanized Steel in factories is 4.5mm or less;High Quality Cold Rolled Steel Coil Galvanized Steel minimum thickness and width are determined according to the equipment capacity and market demand of each plant.

The difference between cold-rolled and hot-rolled steel is not in the smelting process, but in the rolling temperature, or the temperature at which the rolling ends.When the final rolling temperature falls below the recrystallization temperature of the steel, it is called cold-rolled steel.Hot rolled steel is easy to roll, rolling steel efficiency is high, but under the condition of hot rolled steel oxidation, the product surface is dark gray light.Cold rolled steel requires mill power, rolling efficiency is low, and in the rolling process in order to eliminate work hardening but also for intermediate annealing, so the cost is higher, but High Quality Cold Rolled Steel Coil Galvanized Steel surface is bright, good quality, can be directly used to process finished products, so the High Quality Cold Rolled Steel Coil Galvanized Steel is widely used.

High Quality Cold Rolled Steel Coil Galvanized Steel strength is very high, but toughness, poor solderability, relatively hard, brittle, bright surface.
