201 stainless steel and 304 stainless steel pressure difference

The difference between the 201 and 304 stainless steel pipe pressure difference between the stainless steel pipe 201 and 304 pressure: 201 stainless steel is high in terms of strength (pressure withstand), because 201 stainless steel contains high Mn (manganese) content, carbon is also 201 stainless steel, these two Each alloy determines the strength (pressure withstand), and the mechanical overall performance is good for 304 stainless steel. However, the corrosion resistance of 304 stainless steel is two grades higher than that of 201 stainless steel, and there is stainless steel 301 in the middle. "The pressure bearing capacity depends only on the wall thickness of the stainless steel pipe." This sentence is right, thicken the point.
201 steel yield point 275MPa, tensile strength ≥520MPa, elongation 40%
304 steel yield point 205MP resistance strength ≥515Mpa, elongation 40%
The yield strengths of these two materials are not the same. For tubes, the cylindrical thin-walled pressure vessel can be calculated using: P*D/2δ<σt
p: internal pressure of the pipe, D: diameter of the pipe δ: wall thickness of the pipe σt: allowable stress at the design temperature. The strength of the two materials, that is, the allowable stress is not the same, the wall thickness is not the same, then the pressure is not the same. If the wall thickness is the same as 304, the pressure is greater.
The stainless steel tube is differentiated by providing analysis.
