304 Alloy Steel Forged Butt Welding Flange

Application field

In the oil and gas industry, 304 Alloy Steel Forged Butt Welding Flange is used in high-pressure and high-temperature pipeline systems. This Forged Butt Welding Flange is suitable for handling corrosive media in the chemical industry. In the food and pharmaceutical industries, due to its excellent corrosion resistance and hygiene performance, it is suitable for use in food processing and pharmaceutical equipment. It is used in water treatment and shipbuilding industries for fresh water and seawater pipeline systems.

Advantage

The forging process of this Forged Butt Welding Flange endows it with higher strength and toughness. The high chromium and nickel content of 304 alloy steel used in 304 Alloy Steel Forged Butt Welding Flange enables it to perform well in various environments. The size, pressure rating and surface treatment can be customized according to customer requirements.

Raw Material for Forged Butt Welding Flange

Forged steel flange raw material generally is pipe billet, after cutting the billet then continuously hammered it, in this way to eliminate the defects such as segregation and looseness in the ingot.

Material Standard

304 Alloy Steel Forged Butt Welding Flange material normally are carbon steel, alloy steel and stainless steel.

• Stainless Steel Forged Steel Flange: ASTM A182 F304, F316

• Alloy Steel Forged Flange: ASTM A182 F5, F9, F11, F12, F21, F22

• Carbon Steel Forged Flange: ASTM A105, ASTM A694 F42, F46,F52,F60, F65 and F70, ASTM A350 LF2

304 Alloy Steel Forged Butt Welding Flange has a lower carbon content than cast iron flanges, so it is less likely to rust. It has a good streamlined shape and a compact structure, so its mechanical properties are superior to those of cast flanges. If the forging process is improper, the grains will be large or uneven, and hardening cracks will occur. The cost of forged steel flanges is higher than that of cast flanges. Forgings can withstand higher shear and tensile forces than castings. The internal structure of the forging is uniform, and there are no harmful defects such as pores or inclusions in the casting.
