The difference between cold-rolled steel and hot-rolled steel is not in the smelting process, but in the rolling temperature, or the end temperature of rolling. When the final rolling temperature is lower than the recrystallization temperature of the steel, it is called cold rolled steel. Hot-rolled steel is easy to roll and has high rolling efficiency, but under hot-rolled conditions, the steel is oxidized, and the surface of the product is gray and dark.

Damascus steel, also called damasked steel, one of the famous steels of the pre-industrial era, typically made into weapon blades. Manufacture involved a secret carburization process in which a form of wrought iron was heated to red heat in contact with various carbonaceous materials in closed vessels. The result was an iron-carbon alloy containing as much as 1.8 percent carbon.

Mesh surface processingStainless steel can be used in many kinds of patterns. The advantages of making steel plates with textured or textured surfaces are as follows:1) Reducing the "oil can-ning" of metallic roofing materials, a term used to describe the surface of a bright material that is not smooth from an optical point of view.

Advantages:Forming speed, high yield, can be made into a variety of cross section forms, to meet the needs of the use conditions; Cold rolling can produce large plastic deformation of steel, thus raising the yield point of steel. Hot rolling can destroy the casting structure of steel ingot, refine the grain size of steel, and eliminate the defects of microstructure, so that the microstructure of steel is compact and the mechanical properties are improved.Disadvantages:1.

Basics on Choosing Stainless Steel GradeStainless steel is best known for its corrosion resistance, which makes it perfect for a huge variety of applications. There are a wide range of grades available within stainless steel, and these allow it to be useful in numerous different industries.At the same time, this means you have to have the know-how to select the proper grade for your next project. At Wasatch Steel, we’re here to help. Let’s look at some areas to consider when choosing stainless steel grade.FormabilityFor applications that need good formability, avoid the martensitic group.

At present, there are few cases of large area stainless steel curtain wall in the field of building exterior wall. Even if large area is adopted, it often does not pursue its high flatness, but only expresses strong texture.For The Chicago Cloud Gate project, each individual steel plate was CNC machined at the factory, cut with a stainless steel plasma torch 3/8 inches thick, and molded using a coil machine created specifically for the project.

All steels have the same basic iron and carbon composition, but stainless steel also contains a healthy dose of chromium—the alloy that gives stainless steel its famous corrosion resistance.There are multiple grades called stainless steel, each with slightly different alloy composition, and therefore slightly different physical characteristics.Stainless steel must contain at least 10.5 percent chromium. Depending on the grade, it may contain much higher chromium levels, and additional alloying ingredients like molybdenum, nickel, titanium, aluminum, copper, nitrogen, phosphorous or selenium.

Stainless steel is initially produced in slabs, which are then put through a conversion process using a Z mill, which converts the slab into coil prior to further rolling. These wide coils are typically made at around 1250mm (sometimes a little wider) and are known as 'mill edge coils'.These wide coils are further processed using a range of manufacturing techniques such as slitting, where the wide coil is slit into a multitude of strands; this is where much of the confusion around the terminology comes in.

The most basic characteristics of stainless steel wholesale are its rust resistance under atmospheric conditions and its corrosion resistance in various liquid media. (Not easy to rust)The meaning of stainless steel wholesale: stainless steel wholesale is the general term for stainless steel wholesale and acid-resistant steel.
