SUS329J1
Austenitic stainless steel SUS329J1
Overview and features of SUS329J1:
SUS329J1 is a kind of austenitic stainless steel with a duplex structure. It is characterized by high hardness, high strength, good plasticity, toughness, weldability, corrosion resistance, excellent oxidation resistance and pitting corrosion resistance. Moreover, its corrosion resistance in the oxidizing and reducing medium is relatively good, which makes SUS329J1 very suitable for the manufacture of acid-resistant equipment.Chemical composition of SUS329J1 (%):
