产品特性DESCRIPTION

SW·ER2209主要成分为22.5 Cr、8.5 Ni、3 Mo和0.15N，全焊缝金属显微组织通常为双相铁素体-奥氏体。 与其他不锈钢相比，这些不锈钢的特点是抗拉强度高、抗应力腐蚀开裂性以及改善的抗点蚀能力。

The main composition of SW·ER2209 includes 22.5% Cr, 8.5% Ni, 3% Mo, and 0.15% N. The microstructure of the all-weld metal is typically a duplex ferrite-austenite phase. Compared with other stainless steels, these stainless steels are characterized by high tensile strength, resistance to stress corrosion cracking, and improved pitting corrosion resistance.
