Flange Material Types | Silver Valley

The materials of steel flanges mainly include carbon steel, alloy steel and stainless steel. Carbon steel flanges such as WCB are low-cost and suitable for medium and low pressure environments. Alloy steel flanges (such as chrome-molybdenum steel) have higher strength and heat resistance and are suitable for high temperature and high pressure environments. Stainless steel flanges (such as 304, 316) have good corrosion resistance and are often used in chemical, food and other industries.

Steel flanges are widely used, mainly for pipeline connections, equipment inlet and outlet connections, etc., to ensure sealing and stability. They are widely used in petroleum, chemical, power, food, pharmaceutical and other industries.

What is the difference between carbon steel flange and stainless steel flange

The main difference between carbon steel flange and stainless steel flange lies in the material and performance. Carbon steel flange has low cost and high strength, but poor corrosion resistance, and is suitable for medium and low pressure and non-strong corrosion environment.

Stainless steel flange (such as 304, 316) has strong corrosion resistance and is suitable for environments with corrosive media such as chemicals and food, but the price is higher. The two also differ in temperature resistance, strength and processing technology. When choosing, it is necessary to consider the specific working conditions and budget comprehensively.

In which industries are stainless steel flanges used?

Petrochemical industry: used for oil and gas transportation, chemical pipeline connection, to ensure the safe transmission of media.
Food and pharmaceutical industry: its sanitary design and non-toxic characteristics meet the strict hygiene requirements of food and drug production.
Architectural decoration industry: used for building water supply and drainage systems, decorative pipeline connections.
New energy and environmental protection industry: in solar energy, wind power generation and environmental protection equipment, the application of stainless steel flanges is gradually increasing.
Aerospace and automobile manufacturing: used to manufacture high-precision, corrosion-resistant parts.
