I: brand: sus329j1

II: chemical composition:

C: ≤ .8 Mn: ≤ 1. Si: ≤ .75 Ni: 2.-5. Cr: 23.-28.

S: ≥ Austenite stainless steel has good plasticity, toughness, weldability and corrosion resistance, and good corrosion resistance in oxidizing and reducing media. It is used to make acid-resistant equipment, such as corrosion-resistant containers and equipment linings, transportation pipelines, and nitric acid-resistant equipment parts.

iv: physical properties

tensile strength σ b (MPa): ≥ 59 conditional yield strength σ .2 (MPa): ≥ 39 elongation δ 5 (%): ≥ 18

area shrinkage ψ (%): ≥ 4

v: general situation

in practical application. Because of the difference in chemical composition, the former is not necessarily resistant to corrosion by chemical media, while the latter is generally stainless. The corrosion resistance of stainless steel depends on the alloying elements contained in the steel.
