Stainless Steel Sheet

We offer the best product range of STAINLESS STEEL 430, Stainless Steel 440 and Stainless Steel Sheets and Plates.

Stainless Steel 430

  • Material Alloy 430 Annealed Sheet
  • Condition Annealed (AMS 5503)
  • Tensile Strength (ksi) 65
  • Proof Stress 0.2% (ksi) 35
  • Elongation A5% 20-22
  • Hardness Rockwell B (HR B) 86-90

Grade 430 is available in Sheet, Bar (Hexagon, Round), Tube (Square, Rectangular and Round), Wire, Rings.

Grade 430, also known as type WL 1.4016 stainless steel combines good corrosion resistance with good formability and ductility. As Grade 430 has excellent resistance to nitric attack it is well suited to use in chemical applications. Grade 430 is generally used for domestic appliances, flue linings, scientific apparatus etc.

Stainless Steel 440

  • Material Stainless Steel
  • Shape Rectangular, Square
  • Thickness 100-200mm, 200-300mm, 400-500mm
  • Length 1000-2000mm, 2000-3000mm, 3000-4000mm, 4000-5000mm
  • Application Construction, Industry
  • Width 1-50mm, 100-150mm, 150-200mm, 200-250mm
  • Technique Cold Drawn, Forged
  • Dimensions 1500-2000mm, 500-1000mm

Applications:

  • Typical applications include:
  • Rolling element bearings
  • Valve seats
  • High quality knife blades
  • Surgical instruments
  • Chisels


Heat Treatment:

  • Annealing – Full anneal – 850-900°C, slow furnace cool to about 600°C and then air cool. Sub-critical Annealing – 735-785°C and slow furnace cool.
  • Hardening – Heat to 1010-1065°C, followed by quenching in warm oil or air. Oil quenching is necessary for heavy sections. Immediately temper at 150-370°C to obtain a wide variety of hardness values and mechanical properties as indicated in the accompanying table.
  • Tempering in the range 425-565°C is to be avoided because of reduced impact resistance and corrosion resistance. Tempering in the range 590-675°C results in lower hardness (the product become machinable) and high impact resistance.


Welding:-If welding is necessary pre-heat at 250°C and follow welding with a full anneal. Grade 420 filler will give a high hardness weld (although not as high as the 440C), but 309 or 310 will produce soft welds with higher ductility.

  • Alternative Grades
    Grade Why it might be chosen instead of 440C
    440A/B Slightly softer and more corrosion resistant grade needed
    440F High machinability required, with same hardness and hardenability as 440C
    420 Lower strength and hardness needed than any of the 440 Grades
    416 Higher machinability required, and the much lower hardness and strength is still adequate
