304 Stainless Steel coils are austenitic steel coils that are non-magnetic or weakly magnetic. There are many kinds of stainless steel, which can be divided into several categories according to the structure at room temperature:
1. Austenitic type: such as 304, 321, 316, 310, etc.;
2. Martensite or ferrite type: such as 430, 420, 410, etc.;
The austenitic type is non-magnetic or weakly magnetic, and the martensite or ferrite is magnetic.
Most of the stainless steel usually used for decorative tube sheets is austenitic 304 material, which is generally non-magnetic or weakly magnetic, but may also appear magnetic due to fluctuations in chemical composition or different processing conditions caused by smelting, but this cannot be considered as a Counterfeit or substandard.
As mentioned above, austenite is non-magnetic or weakly magnetic, while martensite or ferrite is magnetic. Due to component segregation or improper heat treatment during smelting, a small amount of martensite or ferrite in austenitic 304 stainless steel will be caused. body tissue. In this way, 304 stainless steel will have weak magnetism.

Stainless Steel Sheet/plate/coil is an alloy steel with smooth surface, high weldability, corrosion resistance, 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 is divided into austenitic stainless steel, ferritic stainless steel, martensitic stainless steel, and duplex stainless steel according to the structure state.
Austenitic Stainless Steel:
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:
A steel whose mechanical properties can be adjusted by heat treatment. It has different strength and toughness at different tempering temperatures.
Duplex Stainless Steel: Austenitic and ferrite each account for about half of the structure. When the C content is low, the Cr content is 18% to 28%, and the Ni content is 3% to 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:
It contains 15% to 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.
Stainless steel production mainly includes crude steel smelting, hot rolling, and cold rolling.
