AISI 4130 BLRF Flanges

Piyush Steel manufacturers and exports wide range of AISI 4130 BLRF Flanges were originally created to combat corrosion problems caused by chloride-bearing cooling waters and other aggressive chemical process fluids. Called AISI 4130 Blind Flanges because of its mixed microstructure with about equal proportions of ferrite and austenite, AISI 4130 BLRF Flanges are a family of grades, which range in corrosion performance depending on their alloy content. The chemical composition based on high contents of Cr and Mo, improves intergranular and pitting corrosion resistance, respectively. Additions of nitrogen can promote structural hardening by interstitial solid solution mechanism, which raises the yield strength and ultimate strength values without impairing toughness. Moreover, the two-phase microstructure guarantees higher resistance to pitting and stress corrosion cracking in comparison with conventional stainless steels. Our products are not only sturdy but also affordable as Piyush Steel offer the best prices possible.
