Comprehensive information of 304 stainless steel tube

1、 Basic characteristics and materials

304 stainless steel tube is a universal austenitic stainless steel material, mainly composed of 18% chromium (Cr) and 8% nickel (Ni), with the following characteristics:

Corrosion resistance: It has good corrosion resistance to oxidative acids, alkaline solutions, and organic acids, and is suitable for scenarios with high hygiene requirements such as food and medical care.

High temperature resistance: It can withstand high temperatures up to 800 ℃ and has excellent comprehensive performance.

Processing performance: High toughness, good cold and hot processing formability, widely used in industrial and decorative fields.

Standard difference: It is necessary to distinguish between ordinary 304 stainless steel and food grade 304 stainless steel, with the latter having stricter restrictions on heavy metal content (such as chromium ≥ 18%, nickel ≥ 8%).

2、 Main application areas

304 stainless steel pipes have a wide range of applications, including:

Industrial equipment: chemical equipment, atomic energy equipment, pressure vessels, etc.

In the field of decoration, building railings, furniture, decorative pipes, etc. need to undergo tests such as hydraulic and flattening to ensure strength.

Food and medical: dairy equipment, tableware, medical devices (must meet food grade standards).
