Why choose 304 stainless steel coil?

1. The characteristics of 304 stainless steel are very obvious. Its surface is very smooth, flat and accurate in size. It also has good ductility and toughness. It is usually sold in rolls.

2. The performance of 304 stainless steel coil is mainly reflected in its thermal conductivity, tensile strength and expansion coefficient. Through the experiment, the thermal conductivity can be between 20~500, the specific value can be different according to different processing technology; Tensile strength can reach more than 520;

3. The expansion coefficient of good quality 304 stainless steel rolls is between 20 and 400.

4. In addition, 304 stainless steel coil resistivity and melting point is also very good. Generally, its resistivity can reach 0.73 ohms and its melting point can reach about 1400 degrees.

What are the advantages of stainless steel coil?

1. Stainless steel is the name of a family of iron-based alloys known for their resistance to corrosion and heat. One of the main characteristics of stainless steel is its minimum chromium content of 10.5% and its excellent corrosion resistance compared to other types of steel. Like other steels, stainless steel is composed mainly of iron and carbon, but several other alloying elements are added, the most prominent of which is chromium. Other common alloys found in stainless steel are nickel, magnesium, molybdenum, and nitrogen.

2. stainless steel coil has many desirable properties, which greatly promote its wide application in the manufacture of parts in many industrial sectors. Most importantly, it is very resistant to corrosion due to its chromium content. The minimum content of 10.5% makes steel about 200 times more resistant to corrosion than steel without chromium. Other features that benefit the consumer are its high strength and durability, resistance to high and low temperatures, increased formability and ease of manufacture, low maintenance, durability, aesthetic appearance, and environmental protection and recycling. Stainless steel does not need to be treated, coated or painted once it is in use.

How to grade stainless steel coil?

stainless steel coils have a number of digital grading systems that are specified according to their composition, physical properties and applications. Each type of stainless steel is classified according to its series number and assigned a numerical grade. The most popular series numbers are 200, 300, 400, 600 and 2000. The most common grades are type 304 and 316, which consist of austenitic inconel. Tableware grade stainless steel is found in the 400 series, which is derived from ferrite and martensitic chromium alloys. The type 420 is called surgical steel and the type 440 is called razor blade steel.
