Calculation Chart

Formula of Weight
  • Weight of Stainless Steel Pipes & Tubes
    • OD (mm)-W.T. (mm) x W.T. (mm) x 0.02466 = Kg.per Mtr.
  • Sheet Width Required for rolled and welded pipes
    • O.D. (mm) - THK (mm) x 3.14 = Sheet Width
  • Weight of Stainless Steel Sheets
    • Length (mtr.) x Wdth (mtr.) x Thk (mm) x 8 = Kg Per Sheet
  • Weight of Stainless Steel Circle & BlanksOD(mm) x OD (mm) x Thk (mm) / 160 / 1000 = Kg Per Pcs.
    • Dia. (mm) x dia.(mm) x 0.00623 = PerMtr.
  • Weight of Stainless Steel Hexagonal Rods
    • Dia. (mm) x Dia. (mm) x 0.00679=Per Mtr.
  • Weight of stainless Steel Square Bars
    • Dia. (mm) x Dia. (mm) x 0.00787=Per Mtr.
  • Weight of Carbon Steel Pipes & Tubes
    • Dia. (mm) - W.T. (mm) XW.T.(mm) x 0.02466 = Kg. Per Mtr.
  • Weight of Carbon Steel Sheets & Plates
    • Length (mtr.) x Wdth (mtr.) x Thk (mm) x 7.85 = Kg Per Sheet
  • Weight of Copper Pipes
    • OD (mm) - W.T. (mm) x W.T.(mm) x 0.0256 = Kg.per Mtr.
  • Weight of Lead Pipes(appro.)
    • OD (mm) - W.T. (mm) x W.T. (mm) x 0.0345 = per Mtr.
  • Weight of Lead Sheets (Approx)
    • Length (mtr.) x Width (mtr.) x Thk (mm) x 11.2 = Kg Per Sheet
  • Weight of Alluminium Pipes (Approx)
    • OD (mm) - W.T. (mm) x W.T. (mm) x 0.0082 = Kg per Mtr.
  • Weight of Alluminium Sheets (Approx)
    • Length (mtr.) x Width (mtr.) x Thk (mm) x 2.66 = Kg Per Sheet

Tensile Strength Conversion Table
  • Kg/mm2  x 9.81 = N/mm2=MPa
  • PSi x 0.0007 = Kg/mm2
  • KSi x 1000 = PSi
  • Kg/mm2  x 1.422 = KSi



Specifications

Aisi Type Characteristics Typical Applications
Austentic
304 General purpose stainless steel specially for welded construction For welded construction or wall vessels formed in a number of draws.
321 environ- Stabilized 18/8 type with titanium; Not sensitive to intergranular corrosion within the carbide precipitation range of 420 to 870o C, corrosion resistance comparable to 304. Used in Oxidising corrosive ments, within 420 to 870o for welded construction. No annealing required after welding.
316 High creep strength, superior corrosion resisting properties in reducing atmosphere. Used in industries in such medias as Sulphurous acid, Sulphuric acid, Phosphoric acid, formic acids & various organic acids for better corrosion resistance than 18/8 type.
310 Excellent high temperature properties with good ductility & weldability. Used up to 1150 o C for continuous service & 1050 for intermittent service in oxidising atmosphere.
Ferritic
430 Good Combination of corrosion resistance, useful mechanical properties & good formability. Not hardenable by heat treatment. Utensils, hardwares, fasteners, appliances, furnace parts, Nitric acid processing equipments etc.
Martensetic
410 General purpose corrosion & heat resisting steel; gives maximum corrosion resistance after heat treatment. Hardenable by heat treatment. Cutlery, shafts, cracking tower, bubbler caps & trays for oil & gas industry, beater bars for paper & pulp industries etc.
* Austenitic stainless steels are not hardenable by heat treatment. These can be hardened by cold work    only.
