What is 304 Stainless Steel flange

304 stainless steel flange is one of the many materials for stainless steel flanges. Compared with 201 stainless steel material, 304 stainless steel flange has better corrosion resistance and oxidation resistance.

304 stainless steel flange is a versatile stainless steel widely used in the production of equipment and components that require good comprehensive performance (corrosion resistance and formability). 304 stainless steel is a grade of stainless steel produced according to the American ASTM standard. 304 contains 19% chromium and 9% nickel. 304 is the most widely used stainless steel and heat-resistant steel. Used for food production equipment, Xitong chemical equipment, nuclear energy, etc.

304 stainless steel flanges are of the same type as flanges made of other materials. Common ones include: 1. Flat welding flanges (flat plate flanges), which require the pipe to be inserted into the inner ring of the flange for welding. 2. Weldingneck flange is a flange with a neck, smooth transition section, and welded connection to a pipe. 3. Socket welding flange is a flange with a socket that is connected to a pipe by socket welding.

The most common ones we usually see are flat welding flanges and butt welding flanges. In fact, we can also produce more than ten types of 304 material neck socket welding flanges, butt welding ring neck loose sleeve flanges, integral flanges, etc. They are distinguished according to industry standards, such as in the petrochemical industry, mechanical industry, etc. The production methods of 304 stainless steel flanges are mainly divided into four types: forging, casting, cutting, and rolling.

Application of 304 Stainless Steel

304 stainless steel flange is the most widely used chromium nickel stainless steel, which has good corrosion resistance, heat resistance, low-temperature strength, and mechanical properties. It is corrosion-resistant in the atmosphere. If it is in industrial atmosphere or heavily polluted areas, it needs to be cleaned in time to avoid corrosion. Suitable for processing, storage, and transportation of food. Has good processing performance and weldability. Plate heat exchangers, corrugated pipes, household goods, building materials, chemicals, food industry.
