Allowable stresses of typical ASME materials Carbon SteelSome examples for allowable stress values "S" of typical carbon steels according to Section II, Part D, Table 1A, metric. NB: Please use Section II Part D for all permitted ASME materials. carbon steel
Divide the yield strength by the factor of safety to calculate the allowable stress. For exampleallowable stress of A36 steel = 36,000 psi / 4.0 = 9,000 pounds per square inch.
For example, if a 60,000 psi tensile strength material is used, the Maximum Allowable Stress Value is 15,000 psi. Division 2Governs the design by “Analysis" and incorporates a lower safety factor of 3.
For example, using a material with a 60,000 psi tensile strength, a vessel built under the 1998 edition (safety factor = 4) yields a maximum allowable stress value of 15,000 psi, while a vessel built under the 2001 edition (safety factor = 3.5) yields a maximum allowable stress value of 17,142 psi.
Feb 18, 2009 · A carbon steel like 1045 can be induction hardened to achieve high surface hardness, but it will not have the same allowable contact stress. In what condition do you intend to use the 1045? Quenched and tempered?
Sep 22, 2009 · The maximum allowable shear stress for mild steel is 34,800 psi. The minimum yield shear stress for mild steel is 21,600 psi,.
Shear stress refers to a pressure endured by a material parallel to its face. Shear strength is the material's ability to endure this applied stress. If enough stress is applied to a body it may not return to its original shape. Picture a rubber band. If the band is stretched a little bit it will return to its original shape.
for stainless steel and copper, the allowable stresses shown are 0.60f y. * Reduce allowable stress to 55 MPa within 25 mm of any weld. ** Reduce allowable stress to 97 MPa within 25 mm of any weld.

Corrosion Allowance general. The corrosion allowance is a measure which is used in the maintenance applications. A corrosion allowance of 3.0 mm means that e.g. a wall thickness without any problem may be decrease with 3.0 mm. Mind you, that does not mean than the minimum wall thickness is achieved and the object has reached its end of life.
ASME B31.3 Process Piping Basic Allowable Stress Calculator Module . Calculate ASME B31.3 process piping allowable stress (S), yield stress (SYT) and tensile stress (SUT) from temperature for low pressure piping (ASME B31.3 Table A 1) and high pressure piping (ASME B31.3 Table K 1).
Maximum Allowable Stress Values ASME Pressure Vessel Code. ASME Pressure Vessel Design and Engineering. ASME Pressure Vessel Code Maximum Allowable Stress ValuesThe maximum allowable stress values to be used in the calculation of the vessel’s wall thickness are given in the ASME Code for many different materials.
The allowable stress in carbon steel ERW pipe therefore differs with the grade and standard. A672 Pipe is very competitively priced. This can be used in high temperature and high pressure applications as well.
Low Temperature Carbon Steel (LTCS) is used in piping system when there is a possibility of process fluid temperature falling below 29 degree centigrade during operation. In typical refinery A 106 Gr B material is used for carbon steel and A 333 Gr 6 is used for LTCS in normal operation.
The ultimate strength, or stress of mild steel is around 800 to 840 MPa. So, taking a factor of safety of 4 (four) , the allowable stress works out to 800 ÷4 =200 MPa. Hari om. Hari om.

The stress will decrease as the cross section size of the beam increases Bending stress will often govern since it is often proportional to the square of the length of the beam. While Shear Stress is simply the shear force divided by the beams area, Bending Stress introduces new variables based on the dimensions of the beam to solve for:
ASME B31.1 Power Piping Allowable Stress Data Module . Allowable stress data for ASME B31.1 power piping (Table A US values). Use the ASME B31.1 allowable stress calculators (see link below) to interpolate the US data values, or to convert the US data values to SI units.
