Processing material description
SS400
SS400 low-carbon steel (iron) belongs to the general structural steel. The carbon content of SS400 is not specified in the JIS standard, and is usually between 0.15% and 0.20%. Because the carbon content is low, the steel hardness is soft, and it is not recommended for use in high-strength, high-resistance steels. The main components of the grinding or hardness assurance, the welding properties are good, commonly used in welding structural parts, screws, nuts, small parts, automotive parts, mechanical parts and so on.
SS400低碳鋼(鐵),屬於一般結構用鋼材。SS400的含碳量在JIS標準中並沒有一定的規範,通常約在0.15% - 0.20%之間,也因為含碳量低,所以鋼質硬度較軟,不建議使用於使用於高強度、耐磨或硬度保證的主要部件上,焊接性質良好,常用於焊接結構用零件、螺絲、螺帽、小零件、汽機車零件、機械零件等。

SCM415
SCM415 is a low-carbon alloy structural steel (lower in carbon content than SCM420) and is suitable for carburizing heat treatment. After the carburizing, the hardness of the surface layer of the steel is increased, so that the wear resistance is improved. However, the central part still maintains the toughness and can withstand the impact and load. Often used in the motor shaft, spindle, mechanical parts, pistons and gears and other special wear and load of the workpiece.
SCM415為低碳合金結構鋼(碳含量較SCM420低一些),適合進行滲碳熱處理,滲碳後鋼材表層硬度提高,使耐磨性提升,但中心部位依然保有韌性,更能承受衝擊與荷重。常應用在馬達軸心、主軸、機械零件、活塞及齒輪等各種特殊耐磨與荷重的工件。
