stainless steel coil
1. Coils are further divided into cold-rolled coils and hot-rolled coils, trimmed coils and burr coils
2. The thickness of the cold-rolled coil is generally 0.3-3mm, and there are also cold-rolled sheets with a thickness of 4-6mm, with a width of 1m, 1219m, and 1.5m, which are represented by 2B.
3. The thickness of the hot-rolled coil is generally 3-14mm, and there are also 16mm coils. The widths are 1250, 1500, 1800, and 2000, which are represented by NO.1
4. Rolls with widths of 1.5m, 1.8m and 2.0m are trimmed rolls
5. The width of the burr roll is generally 1520, 1530, 1550, 2200, etc. wider than the normal width.
6. In terms of price, the trimming roll and the raw edge roll of the same model generally differ by about 300-500 yuan.
7. The roll can be opened according to the length required by the customer. Cold rolling is generally flat 1m*2m, 1219*2438 is also called 4*8 feet, and hot rolling is generally flat 1.5m*6m, 1.8m*6m, 2m*6m, and those opened according to these dimensions are called standard plates or fixed-length plates.

Stainless steel coil is divided into Austenitic, ferrite, martensite, duplex (ferrite austenite) stainless steel cold rolled coil and stainless steel hot rolled coil.
Stainless steel coil is widely used in chemical industry, food, medicine, papermaking, petroleum, atomic energy and other industries, as well as various parts of buildings, kitchenware, tableware, vehicles and household appliances.

Element action

Carbon ( C ): 1. Improve the deformation resistance and tensile strength of the blade;

2. Increase hardness and wear resistance.

Chromium (CR): 1. Improve hardness, tensile strength and toughness;

2. Wear and corrosion resistance.

Cobalt (CO): 1. Increase hardness and strength so that it can withstand high temperature quenching;

2. It is used to strengthen some individual properties of other elements in more complex alloys.

Copper (Cu): 1. Enhance corrosion resistance; 2. Enhance wear resistance.

Manganese (MN): 1. Increase hardenability, wear resistance and tensile strength;

2. Removing oxygen from molten metal by separation oxidation and separation vaporization; 3. When added in large quantities, it improves the hardness, but improves the brittleness.

Molybdenum (MO): 1.Enhance strength, hardness, hardenability and toughness;

2. Improve machinability and corrosion resistance.

Nickel (Ni): 1. Enhance strength, hardness and corrosion resistance.

Phosphorus (P): 1. Enhanced strength, machinability and hardness.

2. It is easy to crack when the concentration is too high

Silicon (SI): 1. Improve ductility;

2. Increase tensile strength;

3. Remove oxygen from molten metal by separate oxidation and separate vaporization.

Sulfur (s): 1. Use in small quantities to improve machinability.

Tungsten (W): 1. Increase strength, hardness and toughness.

Vanadium (V): 1. Increase strength, hardness and seismic resistance.

2.Prevent the generation of particles.

Because stainless steel has many ideal properties required by building materials, it can be said to be unique in metals, and its development continues. In order to make stainless steel more neutral in traditional applications, existing types have been improved, and new stainless steel is being developed to meet the strict requirements of advanced architectural applications. Due to the continuous improvement of production efficiency and quality, stainless steel has become one of the most cost-effective materials selected by architects. Stainless steel integrates performance, appearance and use characteristics, so stainless steel will still be one of the best building materials in the world.
