What Is The Difference Between Cold Rolled Steel And Stainless Steel?
Sep 29, 2017

The difference between stainless steel and cold rolled steel is very large. Common cold rolled steel maximum thickness of 8mm, are generally through the hot rolled coil as raw materials, to produce a beautiful and easy to use Cold Rolled Steel dry, each volume can reach 13.5 tons it And stainless steel is different, stainless steel does not specify the thickness, and its raw materials are generally not limited to steel, as well as nickel, chromium, molybdenum, their categories are metal. Stainless steel is a certain degree of corrosion resistance, the general chemical properties will not let it corrosion Oh.

The difference between cold rolled steel and stainless steel

the difference:

① stainless steel is a class of steel, cold-rolled steel is a kind of steel!

② stainless steel is resistant to air, steam, water and other weak corrosive media and acid, alkali, salt and other chemical corrosive media corrosion of steel, also known as stainless steel acid. Practical applications, often weak corrosive medium corrosion of steel known as stainless steel, and corrosion resistance of chemical corrosion of steel known as acid-resistant steel. Due to the difference in the chemical composition of the two, the former is not necessarily resistant to chemical corrosion, while the latter are generally have a rust.

The difference between cold rolled steel and stainless steel

The corrosion resistance of stainless steel depends on the alloying elements contained in the steel. Stainless steel base alloy elements are nickel, molybdenum, titanium, niobium, copper, nitrogen, etc., to meet the various uses of stainless steel organization and performance requirements. Stainless steel is easy to be chloride ion corrosion, because chromium, nickel, chlorine is the same element, the same element will be interchangeable assimilation to form the corrosion of stainless steel.

Cold rolled steel is hot rolled coil as raw material, at room temperature in the recrystallization temperature below the rolling, including the plate and volume, many domestic steel mills such as Baosteel, Wuhan Iron and Steel, Anshan Iron and Steel can produce. Which is called the delivery of steel plate, also known as box or plate; length is very long, rolled into a steel called steel, also known as reel.

The difference between cold rolled steel and stainless steel

③ general cold-rolled steel: refers to the type of carbon steel rolled into the plate of the product (usually rolled into a roll), there are other bar, wire and so on.

Stainless steel refers to the addition of Cr, Ni and other elements of the alloy steel, which represents the steel is 304 stainless steel, stainless steel also distinguish between plates, bars, profiles, wire and so on.

④ cold-rolled steel: its strength is high, but toughness, poor solderability, relatively hard, crisp, bright surface.

Stainless steel: the appearance of the surface and the use of a variety of possibilities of corrosion resistance, better than ordinary steel long-term durability and good corrosion resistance, and thus the possibility of the use of thin plate high temperature oxidation and high strength, it can fire at room temperature processing, Plastic processing because there is no need to surface treatment, so simple, easy to clean, clean finish high welding performance.

The difference between cold rolled steel and stainless steel

We know that stainless steel is a kind of steel, this category is divided into many kinds, such as ferrite stainless steel. Austenitic stainless steel, precipitation hardening stainless steel, etc., and cold-rolled steel is cold-rolled steel, it is only one of their own, unlike the "stainless steel" argument in general. When we buy stainless steel, according to their own needs to buy a different stainless steel, and the purchase of cold-rolled steel is the target of the purchase, buy back the material only a cold-rolled steel, which must be clear.
