Stainless steel bar: Conditions, surface finishes and tolerances

Stainless steel bar

Conditions, surface finishes and tolerances

Stainless and heat resisting bars are produced to various conditions, viz. annealed, hardened (quenched) and tempered, cold drawn, etc. Various surface finishes include hot rolled, pickled, rough machined, peeled, ground and drawn. The tolerances will depend on both the surface finish and the specified range (eg. – only, + and -, + only). The various conditions, surface finishes and tolerances are not applicable to all materials and shapes.

Mass of stainless steel bar in kg1m

Useful formulae:

Round Bar*: (r)2 x 0,00795 (r = radius in mm)

eg 50mm round bar = (25)2 x 0,00795 = 15,61 kg/m

Square Bar*: (di x 0,00795 (d = cross section in mm)

eg 50mm square bar = (50)2 x 0,00795 = 19,88 kg/m t

Hex Bar*: 1,1 x mass of equivalent round bar

eg50mmhexbar= 1,1 x 15,41 = 17,17kg/m

Flat bar*: Wx T x 0,00795 (W & T are width and thickness in mm)

eg 80mm x 12mm flat bar = 80 x 12 x 0,00795 = 7,64 kg/m

Section: G x T x 0,00795 (G = nett girth in mm, T = thickness in mm)

eg 150mm x 75mm x 6mm channel = (150 + 75 + 75 – 6 – 6) x 6 x 0,00795 = 13,74 kg/m *

* For Round, Square and Hex Bar:

Double the size =4 x the mass eg 100mm round bar = mass of 50mm round x 4 = 15,61 x4 = 62,44 kg/m
