Three differences between stainless steel seamless steel pipe and carbon steel seamless steel pipe

2019-04-03


The so-called stainless steel seamless steel pipe and carbon steel seamless steel pipe difference, mainly refers to the stainless steel and carbon steel in the design rules of the difference, that is to say, the two kinds of steel design rules are not universal. These differences are summarized below:

Design rules for stainless steel cannot be applied to carbon steel because there are three fundamental differences between stainless steel and carbon steel.

1.Stainless steel produces work hardening when cold working. For example, bending has anisotropy, that is: transverse and longitudinal performance is different.

The strength increase due to cold working can be used, but if the bending area is small compared with the total area and this increase is ignored, the strength increase can improve the safety factor to a certain extent.

2. The shape of the stress/strain curve is different.

The elastic limit of stainless steel is about 50% of the yield stress, which is lower than that of medium carbon steel as far as the minimum value specified in the standard is concerned.

3. Stainless steel has no yield point, usually expressed asó0.2 the yield stress is considered to be the appropriate value.
