How Stainless Steel Coils Are Made?
Stainless steel coils are the most widely used type of metal coil in the market. They are mainly used for making pipes, tubes and sheets. These stainless steel coils are manufactured using different types of raw materials and advanced technology.
Stainless steel coils are made using several processes like hot rolling, cold rolling and extrusion. The process of making these coils depends on their thickness, diameter, length and width. The most common process used to manufacture stainless steel coils is hot rolling process. It involves melting the raw material at high temperature and then shaping it into desired forms by rolling them through a series of rollers that have varying degrees of hardness. This process results in producing large sized products with a uniform thickness, size and shape.
The second commonly used process is cold rolling process which is carried out under controlled conditions so as to maintain product quality during production stages. In this process, the material undergoes three processes namely roughing pass (first pass), semi-finishing pass (second pass) and finishing pass (third pass). This method produces products with high dimensional accuracy and good surface finish with low yield loss due to less friction during rolling process.
What Are The Advantages of Using Stainless Steel Coils?
Stainless steel coils are an excellent choice for a variety of applications, including heating and cooling systems, food processing facilities and even your home.
They are highly durable and can withstand high temperatures. Selain itu, they offer many advantages over other types of metal coils:
Prolonged Lifespan
Stainless steel coils have a much longer lifespan than copper or aluminum. This means that you will get more use out of these coils before they need to be replaced. They also require less maintenance so you won’t have to worry about repairing them as often as other types of coils.
High-Temperature Resistance
Stainless steel coils can withstand temperatures up to 2,000 degrees Fahrenheit without melting or warping. This makes them ideal for industrial processes that involve extreme heat such as chemical manufacturing and oil refineries. They can also be used in residential applications such as cooking stoves and fireplaces where there is a risk of fire starting due to exposed flames from burning wood or coal fires.
Heat Transfer Efficiency
Stainless steel has excellent thermal conductivity properties that allow it to transfer heat quickly throughout its entire length — unlike other metals that may only conduct heat through their outer layers while their inner layers remain cool.

Stainless steel coil is an alloy steel with smooth surface, high weldability, rintangan kakisan, polishability, heat resistance, corrosion resistance and other characteristics.
It is widely used in various industries and is an important material in modern industry.
Stainless steel coil is divided into austenitic stainless steel, ferritic stainless steel, martensitic stainless steel, and duplex stainless steel according to the structure state.
Austenitic Stainless Steel Coils:
stainless steel with an austenitic structure at room temperature. Steel contains Cr≈18%, Ni≈8%-25% and C≈0.1%. Steel has high toughness and plasticity, but low strength.
Martensitic Stainless Steel Coils:
A steel whose mechanical properties can be adjusted by heat treatment. It has different strength and toughness at different tempering temperatures.
Duplex Stainless Steel Coils:
Austenitic and ferrite each account for about half of the structure. When the C content is low, the Cr content is 18% Untuk 28%, and the Ni content is 3% Untuk 10%. Some steels also contain alloying elements such as Mo, Cu, Si, Nb, Ti, and N. This type of steel has the characteristics of austenitic and ferritic stainless steel
Ferritic Stainless Steel Coils:
It contains 15% Untuk 30% chromium and has a body-centered cubic crystal structure. This type of steel generally does not contain nickel, and sometimes contains a small amount of Mo, Ti, Nb and other elements. This type of steel has the characteristics of large thermal conductivity, small expansion coefficient, good oxidation resistance, and excellent stress corrosion resistance.
What Are The Edges Options of Stainless Steel Coils?
Mill edge is a non-trimmed edge appearance after hot or cold rolling and annealing/pickling process. It usually leaved an irregular pinhole line on the edge side around 10mm to 15mm.
Slit/slitting edge means we will trim irregular pinhole line on our slitting machine.

Copper Coils
It may seem that a copper coil is a simple piece of coiled wire that can be wound and put to use. As with any form of industrial product, copper coils have to be precisely engineered to fit an application. The winding process has to be completed with precision to ensure the proper distance between the wires and the diameter of the opening.
Each product that uses copper coils requires that a certain number of turns be made to provide the correct amount of resistance. Inaccurate calculations can lead to inefficiency and possible failure of the coil or device. For this reason, the engineers at Metal Associates guarantee that they have closely examined the specification of an application such that the diameter, spacing, wire thickness, and number of turns exactly matches the design of the product where the copper coil will be used.
