高铬耐磨铸钢的成份:炭、1.2-1.8％;锰、0.4-0.7％;硅、1.0-1.5％,铬、18-22％。其余为铁及不能清除的其它杂质。另一种除含以上各成分外,再从铌、钼、锆、钛、钒、钨等元素中,任选其中一种以上组合加入,共占成份<7％。其余为铁及其它不能清除的杂质。现将目前各种耐磨钢分别介绍并作比较如下: 高锰钢含:炭、0.9-1.4％;锰、10-14％;经锻造或压制成型后,可用于矿山机械、土木建筑机械等的外筒、履带、导轨接头等,防止磨损。
High chromium wear-resistant cast steel components: carbon, 1.2-1.8%; manganese, 0.4-0.7%; silicon, 1.0-1.5%, chromium, 18-22%. The rest is iron and other impurities can not be removed. The other in addition to the above ingredients, then from niobium, molybdenum, zirconium, titanium, vanadium, tungsten and other elements, one or more of these combinations were added, accounting for the total composition <7%. The rest is iron and other impurities that can not be removed. At present, all kinds of wear-resistant steel are introduced and compared as follows: High manganese steel containing: carbon, 0.9-1.4%; manganese, 10-14%; after forging or pressing, can be used for mining machinery, civil construction machinery, etc. The outer cylinder, track, rail joints, etc., to prevent wear and tear.
