Instruction of Stainless Steel 430 Plates

Grade 430 is a ferritic, straight chromium, non-hardenable grade, combining good corrosion resistance and formability characteristics with useful mechanical properties. Its ability to resist nitric acid attack permits its use in specific chemical applications but automotive trim and appliance components represents its largest fields of application.

Grade 430F is the free-machining version of this grade, available in bar form for use in automatic screw machines. Grade 434 is the molybdenum bearing version of Grade 430 and has the same useful combination of properties. Its molybdenum addition improves corrosion resistance.

Features of Stainless Steel 430 Plates

1. Stainless Steel 430 Sheets And Plates Corrosion Resistance:

Grade 430 has good resistance to a wide variety of corrosive enviornments, including nitric acid and some organic acids. It attains its maximum corrosion resistance when in the highly polished or buffed condition. In general its resistance to pitting and crevice corrosion resistance is close to that of grade 304. Stress corrosion cracking resistance of Grade 430 is very high, as it is for all ferritic grades.

Like other high-sulphur free machining grades 430F has much reduced resistance to pitting and crevice corrosion compared to its non-free machining equivalent.

2.Stainless Steel 430 Sheets And Plates Heat Treatment:

  • Solution Annealing – Heat to 815-845°C, hold for ½ hour per 25mm of thickness, slow furnace cool to 600°C and then quickly air cool. Slow cooling from 540-400°C will cause embrittlement.
  • Sub-Critical anneal – Heat to 760-815°C and then air cool or water quench.
  • This grade is not hardenable by thermal treatment.

3. Stainless Steel 430 Sheets And Plates Welding:

  • Pre-heat at 150-200°C if welding is necessary.
  • Embrittlement in the weld metal and heat affected zone can be relieved by a post-weld anneal at 790-815°C
  • Grain refinement will not occur.

4. Stainless Steel 430 Sheets And Plates Machining:

  • Easier to machine than the standard austenitic grades such as 304.
  • Still a tendency for galling and pick-up on the cutting tool.
  • Bars that have been lightly drawn are easier to machine than those in the annealed condition.
  • Grade 430F, the free machining version of 430, is very much easier to machine.

5. Stainless Steel 430 Sheets And Plates Fabrication:

  • Lower work hardening rate makes bending and forming somewhat easier than for grade 304
  • Lower ductility restricts very severe operations.
  • Severe bends should be made with the bend axis at right angles to the rolling direction.
  • Severe cold heading of 430 wire is possible.

Marking and packaging of Stainless Steel 430 Plates

The packaging of our products (eg. weathered corrugated steel, weathering corrugated steel,corten steel columnl,hot rolled stainless steel plate) ensures that they will not be damaged during transport. For export purposes, the usual export packaging is done in wooden crates or crates. All hr sheet metal, plates and coils are marked with a logo (company mark), grade, size and batch number. On request, we can customise the marking on the product,such as spcc cold rolled steel.
