Martensitic 410 (1Cr13) and ferritic 430 (1Cr17) stainless steel are more common grades in the weaving industry. Stainless steel 410 filter mesh and stainless steel 430 filter mesh are accurately analyzed in three dimensions: chemical composition, material properties, and main uses:
1. Comparison of chemical composition (mass fraction%)
element | 410 (martensite) | 430 (ferrite) | Differential impact |
Cr (chromium) | 11.5–13.5 | 16.0–18.0 | 430 has better oxidation resistance |
C (carbon) | 0.08–0.15 | ≤0.12 | 410 has high hardness and 430 has better corrosion resistance |
Ni (Nickel) | ≤0.75 | ≤0.60 | All contain no nickel (low cost) |
Core differences:
- 410: High carbon + medium chromium → forms hard martensite after quenching
- 430: Low carbon + high chromium → ferrite structure cannot be hardened
2. Material Performance Comparison (Woven Filter Scenario)
performance | 410 (martensite) | 430 (ferrite) | Difference in results |
Corrosion resistance | Weak (rusts in humid environments) | Medium (only resistant to drying acids) | 430 > 410 |
hardness | HRC 40–45 (after quenching) | HRB 80–85 (≈HRC 20) | 410 is 3 times harder |
strength | 700–900 MPa (tensile) | 450–550 MPa | 410 is 60% stronger |
toughness | Low (high carbon brittle) | Very low (ferrite low temperature brittleness) | Shock loads must be avoided |
Weldability | Poor (cold cracking after welding) | Weldable (titanium stabilization required) | 430 > 410 |
wear resistance | Excellent (resistance to particle erosion) | Poor (soft and easily scratched) | 410 lifespan is more than 3 times longer |
Key conclusions:
- 410: Relies on high hardness to achieve wear resistance at the expense of corrosion resistance
- 430: Relying on high chromium content to ensure basic corrosion resistance, sacrificing strength/wear resistance
3. Comparison of main uses (material selection based on performance)
410 Martensitic filter applicable scenarios
- High wear + low corrosion environment:
- Mining vibrating screen (quartz sand/iron ore fines classification)
- Engineering machinery hydraulic oil filter (anti-metal debris scratching)
- Coal separator sieve plate (gangue impact protection)
- Prohibited scenarios: coastal areas, pickling lines, food processing (contact with chloride ions/acid will cause rapid corrosion)
430 Ferrite filter applicable scenarios
- Drying + low cost requirements:
- Building protection net (indoor dry environment)
- Grain screening (wheat, corn and other neutral materials)
- Household range hood filters (low grease environment)
- Prohibited scenarios: Shipbuilding, chemical industry, humid outdoor areas (chloride ions cause pitting and perforation)
4. Practical selection comparison table
Filter material selection comparison table
Working condition characteristics | Select 410 | Select 430 | Consequences of wrong choices |
Contains sand and gravel/metal debris | (wear resistance first) | (Rapid wear failure) | 430 filter perforated for 1 month |
humid coastal air | × (Rust blocks the mesh) | × (pitting leakage) | Duplex steel 2205 is the right choice |
Neutral water below 80℃ | △ (short-term availability) | ✓ (Cost Optimum) | 410 may rust and affect water quality |
Filter mesh needs to be welded and spliced | × (brittle crack in weld area) | ✓ (capable of argon arc welding) | 410 has high risk of fracture after welding |
- 410 Martensite: Choose it as a "wear-resistant shield" - it can withstand sand and gravel erosion, but is afraid of water and acid.
- 430 Ferrite: Choose it as the "economic barrier" - saves costs and resists oxidation, but is afraid of wear and chlorine.
The iron rule to avoid pitfalls: both are useless in humid environments, upgrade to duplex steel in corrosive environments!
This article compares the core characteristics of duplex steel (represented by 2205) and super duplex steel (represented by 2507) in braided filtration applications, with an in-depth analysis from three aspects: chemical composition, material properties, and application areas:
1. Chemical Composition Comparison (Core Alloy Design Differences)
element | 2205 (standard duplex steel) | 2507 (super duplex steel) | Functional impact |
Cr | 2 2 –23% | 24–26% | Improve corrosion resistance and high-temperature oxidation resistance |
Ni | 4.5–6.5% | 6–8% | Stabilize austenite phase and enhance toughness |
Mo | 3.0-3.5 % | 3–5% | Significantly improved resistance to pitting/crevice corrosion |
N | 0.14–0.20% | 0.24–0.32% | Enhance strength and inhibit σ phase precipitation |
2507 achieves a leap in corrosion resistance through its ultra-high chromium, molybdenum and nitrogen content, and can withstand chloride environments with concentrations 10 times that of 2205.
2. Material Performance Comparison (Advantages of Braided Filter Core)
performance | 2205 | 2507 | Core Advantages |
Corrosion resistance | Resistant to seawater/moderate acids (e.g. acetic acid, phosphoric acid) | Resistant to boiling seawater/concentrated hydrochloric acid/hydrofluoric acid | 2507 is used for strong acid filtration and its service life is increased by 3-5 times |
tensile strength | 620–750 MPa | 800–1000 MPa | 2507 can withstand high pressure (such as 300 meters deep sea) |
hardness | HRC 28–32 | HRC 32–35 | 2507 has 40% higher wear resistance than 2205 |
Temperature adaptability | -50℃~300℃ | -80℃~400℃ | 2507 is suitable for LNG deep cold filtration and high temperature steam |
Stress corrosion resistance | (Better than 316L) | (No risk of cracking) | 2507 is safe to use in sulfur-containing oil and gas fields |
Weaving processability | The cold working rate needs to be controlled (deformation rate ≤ 30%) | Intermediate annealing is required (high strength leads to increased wire breakage rate) | 2205 is easier to weave complex structure filter |
3. Application Field Comparison (Selection Guide for Harsh Working Conditions)
2205 Duplex Steel Filter Core Scene
- Marine engineering: seawater desalination pretreatment filter basket, ship ballast water filter
- Chemical industry: acetic acid reactor filter (concentration ≤ 80%), phosphoric acid evaporator filter plate
- Energy: geothermal well sand control screens, oilfield water injection filters (Cl⁻≤20,000 ppm)
- Cost-sensitive upgrade: Replace 316L filter, double the lifespan, and increase the cost by only 30%
2507 Super Duplex Steel Filter is Irreplaceable
- Extreme corrosion:
- Concentrated hydrochloric acid delivery pipeline filter (concentration ≥ 30%)
- Hydrometallurgical electrolyte filter (including HF/mixed acid environment)
- High-pressure and severe environment:
- Deep sea drilling mud screen (resistant to 300 bar water pressure + high Cl⁻ corrosion)
- Nuclear power spent fuel pool cooling water filtration system
- High temperature and high wear:
- Flue gas desulfurization slurry filter basket (80℃ + gypsum particle flushing)
- Refinery hydrogenation reaction product filter (400℃/H₂S environment)
Duplex steel 2205 → The most cost-effective steel for corrosion conditions in seawater and chemical industries, with a balance of strength and corrosion resistance
Super Duplex Steel 2507 → The ultimate solution for extreme corrosion/high pressure/high temperature scenarios, with high initial cost but the lowest lifecycle cost
