GradeS275JR是欧洲钢级非合金结构钢。这是一种普通的低碳钢/碳钢板。
S275JR钢的含义:S275JR结构等级(S)最低屈服强度为275 N/mm²m, JR的名称确认了该钢在室温27J(焦耳)下经历了纵向Chary v -缺口冲击试验。其他Charpy名称包括J0, J2和K2。
S275JR steel plates are mainly for multiple structural applications e.g. manufacturing plant, machinery, mining equipment and vehicles, excavators, loader, bulldozers, crane, mining hydraulic supports, construction, power plant, sugar mill, palm oil mill, oil and gas, port equipments, fans, drilling rigs.
