ASTM A182 F51 flange

ASTM A182 F51 is a high-strength and corrosion-resistant stainless steel material. It is a duplex stainless steel with a high Cr content and an appropriate amount of alloy elements such as Ni and Mo. These elements can form a strong corrosion-resistant layer to prevent the medium from corroding the material. The main characteristics of ASTM A182 F51 include corrosion resistance, excellent mechanical properties, weldability and processability.
