The SR elbows referred to the short radius elbows or bends which is equal to the NPS in inches(R=1.0D). The 45, 90°and 180°elbows, all three in the "long radius" version, and in addition the 90° and 180° elbows both in the "short radius" version. World iron&steel supply 90 ° SR elbow, 180° SR elbow made the material of carbon steel, alloy steel elbow and stainless steel .
