② 钢材材质+SR的SR代表什么
SR 消除应力 热处理(Stress Relieving)
③ SR24 RB 6MM-10MM钢材是什么钢材
SR24是一种结构钢,RB 6mm~10mm指直径6毫米~10毫米。
SR24 steel is a structural billet steel for structural applications.
Maximum percentage of Carbon (C) is 0.25.
Maximum percentage of Manganese (Mn) is 0.9.
Maximum percentage of Phosphorous (P) is 0.050 percent.
Maximum percentage of Sulphur (S) is 0.050 percent.
Maximum percentage of Silicon (Si) is 0.350 percent.
Remaining is iron (Fe) percentage and with few negligible impurities.
The tensile strength of the SR24 Steels is expressed in Newton per millimeters and it must be at-least 382 N/mm2 (MPa). The yield strength is minimum 235 N/mm2 (MPa). The minimum percentage ranges for elongation is 24% thicknesses.
