非常適合做刀具,但防銹能力並不好。
② 鋼材材質+SR的SR代表什麼
SR 消除應力 熱處理(Stress Relieving)
③ SR24 RB 6MM-10MM鋼材是什麼鋼材
SR24是一種結構鋼,RB 6mm~10mm指直徑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.
