ST12 steel sheet

St12 is the cold steel plates under the standard of D2N 1623-(1)1983 cold rolled low carbon steel and strip. St12 cold steel mainly for commercial. St12 cold steel mainly for commercial. For the St12cold rolling steel and strip specification lists, the thickness of 0.3-3.5 mm and width from 120-1850 mm are all available by our company
Product introduction

ST12 Steel Sheet

ST12 cold rolled steel is essentially hot rolled steel that has been processed further. Once hot rolled steel has cooled, it is then rolled to achieve more exact dimensions and better surface qualities.

Cold rolled steel sheet(CR steel sheet)is essentially hot rolled steel that has been processed further

Cold 'rolled' steel plate is often used to describe a range of finishing processes—though, technically, 'cold rolled' applies only to sheets that undergo compression between rollers. Things like bars or tubes are 'drawn,' not rolled. Other cold finishing processes include turning, grinding and polishing—each of which is used to modify existing hot rolled stock into more refined products.

 

ST12 cold rolled steel coil can often be identified by the following characteristics:

1.Cold rolled steel has better, more finished surfaces with closer tolerances

2.Smooth surfaces that are often oily to the touch in CR steel sheet

3.Bars are true and square, and often have well-defined edges and corners

4.Tubes have better concentric uniformity and straightness,made from cold rolled material.

5.Cold rolled steel coil with better surface characteristics than hot rolled steel, it's no surprise that cold rolled steel is often used for more technically precise applications or where aesthetics are important. But, due to the additional processing for cold finished products, they come at a higher price.

 

In terms of their physical characteristics, cold worked steels are typically harder and stronger than standard hot rolled steels. This is because cold rolled steel finishing essentially creates a work-hardened product. It's worth noting that these additional treatments can also create internal stresses within the material. In other words, when fabricating cold-worked steel—whether cutting, grinding or welding it—this can release tensions and lead to unpredictable warping.

Product Applications

ST12 cold rolled steel sheet,cold rolled steel coils applications: construction,machinery manufacturing, container manufacturing, shipbuilding, bridge construction. CR steel sheet can also be used to manufacture a variety of containers.

ST12 steel also coud used for the furnace shell,furmace plate,bridge and

vehicle static steel plate, low alloy steel plate,shipbuilding plate, boiler plate, pressure vessel plate, pattern plate, tractor parts, automobile frame steel plate and welding components.

Packaging & Shipping

ST12 cold rolled steel plate cold be packaged by brown paper and iron box,cold rolled steel coil could be packaged with steel belt and iron box .Mill's Standard Export Sea-worthy Packing will suitabel for CR steels.

Our Service

1.All of the CR steel have 1-year guarantee from the day installation.

2.All of the specification of the cold rolled steel coil and other details will be never reveal to any third companies.

3.We could cut the cold rolled steel from steel coil to steel sheet,the size will be do as you required.

4.We colud also welding the cold rolled steel plate use two CR steel plate.
