The preparation of embodiment 2 abrasion-resistant stee 2
Prepare abrasion-resistant stee 2 according to the mode identical with embodiment 1, be different in that and do not use cobalt。
The preparation of embodiment 3 abrasion-resistant stee 3
Prepare abrasion-resistant stee 3 according to the mode identical with embodiment 1, be different in that and do not use niobium。
Experimental example 1
The Brinell hardness of abrasion-resistant stee 1-3 is measured according to GB/T231.1-2009。Result is as follows: the Brinell hardness of abrasion-resistant stee 1 is 289HRC, and the Brinell hardness of abrasion-resistant stee 2 is 216HRC, and the Brinell hardness of abrasion-resistant stee 3 is 232HRC。The Brinell hardness of abrasion-resistant stee 1 compared with abrasion-resistant stee 3, has significant difference (P < 0.05) with abrasion-resistant stee 2。
