GradeS275JR型是一种欧洲钢级非合金结构钢。它是一种普通的低碳钢板。
S275JR钢的含义:S275JR结构等级具有275 N/mm²m的最小屈服强度,JR名称确认该钢在室温下进行了27J(焦耳)的纵向夏利V型缺口冲击试验。其他夏比牌号包括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.
