The first choice for cold-rolled strips is Dongguan Boyang Metal Factory, which sells cold plates, cold-rolled plates, steel strips in stock at low prices, materials, what materials they are, how much does cold-rolled plate cost per ton, what material is cold plate, cold-rolled plate price, imported cold-rolled plate Rolled plate, imported cold plate, cold plate bending, deep drawn cold plate, drawn cold plate, cold plate stretching, deep drawn cold plate, deep drawing cold rolled plate, cold rolled plate bending, stretched cold rolled plate, Cold-rolled deep drawing plates, cold-rolled plates and other cold-rolled steel materials, with excellent quality, complete specifications, spot and low-price wholesale and retail, flat plate, slitting, cutting and processing services according to user needs, special specifications, hardness, positive and negative tolerances, surface Can be produced and customized according to customer requirements.
Cold rolled strip surface quality standard:
Surface accuracy:
Ordinary thickness accuracy. Higher thickness accuracy
Ordinary width accuracy. Higher width accuracy
Ordinary length accuracy. Advanced length accuracy
Ordinary unevenness accuracy. Higher unevenness accuracy
Higher-level finished surface (B): A small number of defects that do not affect formability and coating and plating adhesion are allowed, such as slight scratches Wounds, indentations, pitting, roller marks and oxidized colors, etc.
High-grade surface (): The better side of the two sides of the product has no obvious defects visible to the naked eye, and the other side should at least meet the requirements of B.
Super high-grade surface (): The better side of the two sides of the product should not have defects that affect the appearance quality after painting or the appearance quality after electroplating, and the other side should at least meet the requirements of (B).
Composition: ..,
Hardness: /hard is, /hard is, /hard is annealed state is, standard quenching and tempering is
Mechanical properties: tensile strength 3-, yield strength< br/>High-quality cold-rolled plates have good surface quality, clear bright annealing images, no serious scratches, no concave unevenness, no pitting corrosion points, no trachoma defects and other high dimensional accuracy. Coupled with annealing treatment, their mechanical properties and The process performance is better than that of hot-rolled thin steel strip. In many fields, especially in the field of home appliance manufacturing, it has gradually been used to replace hot-rolled thin steel strip.
,,, English acronym means steel, means plate, means cold rolling, means deep drawing grade
Cold rolled strip product uses: used in saw blades, mud boards, motors, rolling door springs, Clock springs, locks, standard parts, electrical fasteners and other industries.
Uses of cold-rolled plate products: construction, underground engineering, bridge structures, marine structures, container manufacturing, automobile industry
Boyang Metal's spot cold-rolled plates/plate material grades:,,3,B,B, B, 3. The stock specifications for the above products are (thickness), and the thickness allowable deviation is divided into two levels of precision: B and B.

The direct-selling brands include Nippon Steel Cold-rolled Steel, Posco Cold-rolled Steel, and Zhonghong Cold-rolled Steel. When purchasing metals, choose Boyang manufacturers to wholesale cold-rolled strips in stock at low prices. , deep drawing cold plate.
Overview:
A steel grade of Japanese Steel (Standard Series), which represents cold-rolled carbon steel plates and steel strips (coils) for deep drawing, and is suitable for deep drawing and drawing purposes.
Explanation of naming:
The first code indicates material, which means steel.
The second code indicates the shape type and use, indicating plate
The third code indicates the steel type, indicating cold rolling
The fourth code indicates the stamping level, indicating deep drawing grade
Cold rolled carbon Plain steel plate and steel strip (coil) quenching and tempering code (heat treatment type): annealed state is, / hardness is, / hardness is, hardness (standard hardness) is
Surface structure number: pitted surface is, bright surface is B.
Chemical composition:,.,.3,.3,
Mechanical properties: Yield strength R/, tensile strength
3 Main uses:
Deep drawing with tensile strength , the deep drawing performance is higher than that of , you can choose or , or , for stamping that does not involve stretch punching, or , or , for deep drawing.
There is no clear number for yield, the tensile strength is not less than the extension, and not less than
There is no clear number for yield, the tensile strength is not less than the extension, and not less than
Its yield is not greater than the tensile strength, not less than the extension, and not less than
The above are their performance. As for the advantages and disadvantages, you have to see where they are used.
