SUS304 is a common type of stainless steel material and is widely used in various industrial and daily life fields.

In engineering design and manufacturing, Q235 steel is a commonly used carbon structural steel, with extensive applications and significant importance.

Sheet materials are also sold as a form of material, often referred to as iron sheets or steel sheets, and are used in industrial products and construction sites, etc.

Thin plates are widely used in various components of products such as automobiles and home appliances. They possess a variety of different characteristics. For instance, depending on the manufacturing method, some have high precision; and depending on the material, some have better magnetic properties.

Galvanized seamless steel pipe refers to a type of seamless steel pipe where, on both the inner and outer surfaces, a layer of zinc is coated through processes such as hot-dip galvanizing or electro-galvanizing, in order to achieve the purpose of corrosion prevention.

The hardness of carbon steel seamless pipes is a very important mechanical property index. It directly affects the wear resistance, plastic deformation resistance and processing performance of the pipes. Its hardness is not a fixed value but is influenced by multiple factors and varies according to different application requirements.
