| 发明名称 | Hadfield steel | ||
| 摘要 | Hadfield steel and a method for obtaining the same, which steel has better mechanical properties than basic Hadfield steel, without detriment to any of them, which has a homogenous grain size distribution, thus allowing new applications, having the following chemical composition: 0.90 to 1.35% by weight of C,11.00 to 14.00% by weight of Mn,0.80% maximum by weight of Si,0.07% maximum by weight of P,0.05% maximum by weight of S andan amount of hafnium greater than or equal to 0.01% and less than 0.1% by weight, the rest being iron and impurities associated with iron, and where the percentages are expressed by weight with respect to the total weight of the steel. | ||
