01 / Calculate stock weight
02 / Find a grade
Use the toolkit worldwide. Material sales and delivery enquiries are currently within India.
Find an equivalent in seconds
Search by Indian, American, European, German, British, Japanese or Chinese designation. Review available designation leads, chemistry, mechanical properties and typical uses. Nearest grades are not automatically interchangeable.

Full gauge table
SWG (British Standard Wire Gauge, BS 3737) is used for sheet and wire; BWG (Birmingham Wire Gauge) for tube walls. Weights are for 1 m² of steel sheet at 7.85 g/cm³.
Paste the chemistry from a mill test certificate to compare reported values with the reference limits in this toolkit, element by element. Results are a screening aid; they do not establish material compliance or certify a grade.

Add a buyer’s specification (check heats against your customer’s own limits)
CEV (IIW) = C + Mn/6 + (Cr+Mo+V)/5 + (Ni+Cu)/15. Pcm = C + Si/30 + (Mn+Cu+Cr)/20 + Ni/60 + Mo/15 + V/10 + 5B.
Limits are heat (ladle) analysis in wt%, from the first standard listed for each grade; where limits change with thickness, the thinnest bracket is used. This is a screening aid, not a certificate of conformity. Final acceptance depends on the standard edition, product analysis tolerances, mechanical tests and the purchase order.
Material detailsDensity: 7.85 g/cm³
Estimate costOptional rate per kg
Theoretical weight from nominal size and density. Actual weight varies within mill tolerances.
Pressure figures are inherited equation estimates, not certified ratings, hydrotest instructions or engineering approval. Confirm allowable stress, temperature, fabrication factors, corrosion and the governing code with a qualified engineer.
Pressure estimate screening only · straight-pipe equation assumptions
S is filled with the B31.3 allowable at ≤38 °C (100 °F): the lesser of UTS/3 and ⅔ of yield. For higher temperatures, type the code allowable at your design temperature. Both results below use the minimum wall (nominal minus mill tolerance minus corrosion allowance).

5S, 10S, 40S and 80S per ASME B36.19M (stainless). Sch 5, 10, 20, 30, 40, 60, 80, 100, 120, 140, 160, STD, XS and XXS per ASME B36.10M (carbon and alloy). Matching S schedules share a column in the complete chart; differing values follow the heading order. STD / XS and Sch 40 / 80 can differ. Weights are theoretical.
Pressure ratings are an engineering estimate, not a design approval. B31.3 MAWP = 2·S·E·W·t ÷ (D − 2·Y·t), with W = 1.0 and Y = 0.4 (valid for t < D/6 and below the creep range). Barlow = 2·Sy·t ÷ D ÷ safety factor, a quick yield-based check. Flanges, fittings, valves and branch connections often rate lower than the pipe. Have the piping design checked by the responsible engineer.

Full table, all sizes
Center-to-end and length dimensions per ASME B16.9. Wall thickness and bevel match the pipe schedule ordered. Weights are published approximate weights for carbon steel, STD and XS walls. Stainless butt-weld fittings to MSS SP-43 (5S/10S) are lighter.
A fitting class is not a pressure value or a universal pipe-schedule match. Confirm the exact standard, fitting type, connection, size and required wall thickness. This reference does not assign a pressure rating to an assembled line.
Confirm the fitting standard, material, pressure class or wall schedule, connections and design conditions for the order. NPT threads follow ASME B1.20.1; confirm any BSP requirement separately. Unions use MSS SP-83 and swage nipples use MSS SP-95 references. Branch outlet fittings use MSS SP-97 references. Check the applicable edition and dimensions before procurement.

Hardness and tensile strength (approximate, carbon and alloy steel)
Type any one value. Hardness scales per ASTM E140 Table 1; approximate tensile strength per ASTM A370 Table 3 / SAE J417, for carbon and alloy steels in the annealed, normalised or quenched-and-tempered condition. Not valid for austenitic stainless, cold-worked material or non-ferrous metals. Expect ±10% on tensile.
