高强度结构用钢板，，，，，具有高的强度和优异低温韧性，，，，，焊接性能优良。。。。。。。主要用于制作高强度工程机械焊接结构、煤炭开采装备（液压支架、刮板运输机）、起重机吊臂支腿、车架、推土机、自卸车、钻井平台、钻机、钢结构等。。。。。。。凭证用途可分为60-80kg级高强度结构钢板、60-90kg级低焊接裂纹敏感性高强度钢板、淬火回火超高强度钢板等系列产品。。。。。。。
High strength steel plates for structure have high strength, good low temperature toughness in addition to the excellent welding performance. They are mainly used for the fabrication of the high strength welding structure of construction machinery, coal mining equipment（hydraulic support, scraper conveyer）,boom, outrigger, frame , bulldozer, dump truck, drilling platform ,drilling rig and steel structure and so on. According to purpose，，，，，there are 60-80kg high strength steel plates，，，，，60-90kg low welding crack sensitive steel plates, quench and temper ultra-high strength steel plates etc.
