1﹑Material Summary and Applications
Austenitic type acid-proof steel, low carbon.
Good resistance to intergranular corrosion and good cold work performance.
Good resistance to oxidized acid (nitric acid), aqueous alkali, most of organic acid and inorganic acid.
It is suitable for deep drawing parts, acid conveying pipeline and acid container.
304H has good corrosion resistant, welding performance and hot resistant performance.
304H mostly used in large boiler heater, reheater, steam pipeline, heat exchanger and other corrosion resistant parts
