Carbon steel, also called carbon steel, refers to an iron-carbon alloy with a carbon content of less than 2%.

The main component of stainless steel is Cr (chromium). Only when the Cr content reaches a certain value, the steel has corrosion resistance. Therefore, stainless steel generally has a Cr (chromium) content of at least 10.5%.

Type 316 - After 304, the second most widely used steel type, mainly used in the food industry and surgical equipment, the addition of molybdenum gives it a special structure that resists corrosion. Because it has better resistance to chloride corrosion than 304, it is also used as "marine steel". SS316 is usually used in nuclear fuel recovery devices. Grade 18/10 stainless steel is also generally qualified for this application grade.

Traditional fingerprint-resistant boards basically use electro-galvanized sheets as the substrate. With the continuous improvement and development of hot-dip galvanizing technology and processes, the surface quality of hot-dip galvanized sheets has now reached a level comparable to that of electro-galvanized sheets.

Fingerprint-resistant board is a composite coated board obtained by performing fingerprint-resistant treatment on the surface of galvanized sheet. Fingerprint-resistant steel plate is the first material to pass environmental certification. Because the surface will not leave fingerprints when touched with a clean finger, it is named "fingerprint-resistant". The surface of fingerprint-resistant steel plate is smooth and flat with small tolerances.

Non-oriented electrical steel is a silicon steel sheet produced by electromagnetic induction cold rolling process. It has no obvious orientation and has excellent magnetic permeability and permeability. It is widely used in electrical equipment such as transformers and motors.
