S32750 (2507, F53, 1.4410) super duplex stainless steel overview:
S32750 (2507, F53, 1.4410) super duplex stainless steel consists of 25% chromium, 4% molybdenum and 7% nickel.
S32750 dual-phase steel has strong strength and corrosion resistance, which is mainly used in chemical processing, petrochemical industry and submarine equipment.
S32750 dual phase steel has strong resistance to chloride corrosion, high thermal conductivity and low thermal expansion coefficient.
High content of chromium, molybdenum and nitrogen it has high resistance to spot corrosion, crack corrosion and general corrosion.
S32750 dual-phase steel also has a high impact strength and is not suitable for use at temperatures above 570 ° c, where its toughness decreases over time.
S32750 dual phase steel has integrated many ferritic steel and austenitic steel is the most beneficial properties, because the steel chromium and molybdenum content is very high, so has excellent resistance to corrosion, crevice corrosion and the ability of uniform corrosion, duplex microstructure ensures that the steel has the ability of high resistance to stress corrosion cracking, and the mechanical strength is high.
S32750 2507 F53 1.4410 Chemical composition of stainless steel
S32750 (2507, F53, 1.4410) super duplex stainless steel physical and mechanical properties:
1. S32750 (2507, F53, 1.4410) dual-phase steel density: 8.0g/cm3.
2. Tensile strength of S32750 (2507, F53, 1.4410) duplex steel strength of extension: σb≥800Mpa.
S32750 (2507, F53, 1.4410) two-phase steel yield strength: σ0.2≥550Mpa
4, S32750 (2507, F53, 1.4410) duplex steel elongation: δ≥15%.
5. S32750 (2507, F53, 1.4410) dual-phase steel hardness (HB) : 310
S32750 (2507, F53, 1.4410) super duplex stainless steel corrosion resistance:
1. Compared with 904L, S32750 dual-phase steel has stronger corrosion resistance to dilute sulfuric acid mixed with chloride ions.
904L is an austenitic alloy specially designed to resist the corrosion of pure sulfuric acid.
The higher chromium and molybdenum content of S32750 dual-phase steel makes it more resistant to overall corrosion of organic acids such as acid and acetic acid.
S32750 duplex steel also has strong corrosion resistance to inorganic acids, especially those containing chlorides.
Grade 316L cannot be used in hydrochloric acid environments where it may be subject to local or global corrosion.
S32750 dual phase steel can be used in dilute hydrochloric acid environment, with strong resistance to spot damage and crack corrosion ability.
2. Intercrystalline corrosion S32750 dual-phase steel has a lower carbon content, which greatly reduces the risk of intercrystalline carbide precipitation during heat treatment. Therefore, this alloy is highly resistant to carbon-related intercrystalline corrosion.
3. Stress corrosion cracking: due to its high alloy content, the corrosion resistance and strength of S32750 dual-phase steel are better than that of 2205.
S32750 dual - phase steel composite structure makes it more resistant to stress corrosion cracking ability.
4, corrosion and corrosion: there are many ways to test the corrosion resistance of steel products in solution containing chloride. The critical temperature for corrosion and corrosion of high-performance stainless steel at 1M sodium chloride solution is specified.
Various experimental results show that S32750 dual - phase steel has excellent corrosion resistance.
5, crack corrosion: cracks in the building and other aspects are almost inevitable, which makes stainless steel more vulnerable to corrosion in the chloride environment.2507 dual - phase steel has a strong anti - crack corrosion ability.
