High Quality Abrasion Resistant Steel Plates
|
1 主要用途/ Main Application |
济钢公司提出建立的《工程机械用高强度耐磨钢板》国家标准GB/T 24186正式实施,耐磨钢作为关键材料在工程建筑机械、采矿、冶金、土木工程及农业机械等行业中抵抗磨损部件的设计应用,如挖掘机,球磨机,翻斗车,刮板机等。
The National Standard GB/T 24186-2009 ”High strength abrasion resistant steel plates for construction machine”,which was proposed and established by Jinan Iron & Steel, Co., Ltd, was carried into execution formally. As the pivotal material, abrasion resistant steel was applied to the fields of Construction Machinery, Mining, Metallurgy, Civil Engineering and Agriculture Machinery, etc, concretely such as Excavator Grab, Ball Mill, Tip Lorry, and Scraper, etc.
