Perbedaan antara pipa seamless stainless steel dan pipa seamless baja karbon dalam aturan desain

The difference between stainless steel seamless tubes and carbon steel seamless tube mainly refers to the difference in design rules between stainless steel and carbon steel, that mean, the design rules of these two types of steel are not commonly used.

These differences are summarized as follows:

The design rules for stainless steel cannot be used for carbon steel because there are three fundamental differences between stainless steel and carbon steel:

1. Stainless steel undergoes pengerasan kerja during cold working, for example, it has anisotropy when bent, that is, the transverse and longitudinal properties are different. The increased strength by cold working can be used, but if the bending area is small compared to the total area and this increase is ignored, the increased strength can increase 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 kekuatan luluh. As far as the minimum value specified in the standard is concerned, the yield stress value is lower than that of medium carbon steel.

3. Stainless steel has no yield point. Usually ó0.2 is used to indicate that the yield stress is regarded as an equivalent value.
