① Yield Point: For pipe fittings of the stainless steel category, the specified non-proportional elongation strength Rp0.2 is used. For pipe fittings of other material categories, when the lower yield strength ReL is not clearly defined, the specified non-proportional elongation strength Rp0.2 is used.
