1.4563 is an ultra-low carbon austenitic alloy with excellent corrosion resistance and is suitable for harsh corrosive media in the chemical industry. The alloy exhibits good uniform corrosion resistance in wet phosphoric acid, and has resistance to pitting, crevice corrosion, intergranular corrosion and stress corrosion cracking. Its comprehensive performance is superior, and it has been widely used in the chemical processing industry in recent years.
The chemical composition of this alloy is as follows:
Carbon(c): 002%
Silicon (Si): 100%
Manganese (mn): 20%
Phosphorus (p): 002%
Sulfur (s): 0015%
Nickel (Ni): 31%.
Chromium (CR): 27%.
Molybdenum (Mo): 35%
Iron (Fe): Margin.
Copper (Cu): 100%
In terms of corrosion resistance, the alloy excels with features including:
Good uniform corrosion resistance, better than 904L in H2SO4, good performance in H3PO4, better than general stainless steel in HCl, HF and HNO3.
Very low carbon content, with good intergranular corrosion resistance, corrosion resistance does not decrease after multiple welding, and also performs well for crevice corrosion of pitting corrosion.
The physical properties of the alloy include a density of 80g cm, the melting point is 13501370, the specific heat capacity is 450530j kg·k, and the thermal conductivity is 114~16.7W (m·k), the modulus of elasticity is 200MPa.
1.4563 is mainly used in wet phosphoric acid production, seawater treatment, chemical processing of fluorine-containing *** and organic acid production. In concentrated H3PO4, it can be used as an ideal alternative material for graphite heat exchangers.
Compared with the previous stainless steel product, 14563 has a lower carbon content and therefore has better resistance to intergranular corrosion. In addition, 14563 also has relatively better corrosion resistance in the chemical industry and is suitable for more kinds of corrosive media, making it widely used in the chemical processing industry.
