在材料成份表的下面有個(gè)說(shuō)明:BORON—Standard killed carbon steels, which are fine grain, may be produced with a boron addition to improve hardenability. Such steels are produced to a range of 0.0005 to 0.003% boron. These steels are identified by inserting the letter “B” between the second and third numerals of the grade number, for example, 10B46. The UNS designation is also modified by changing the last digit to “1” to indicate boron, for example, G10461. 看了這個(gè)你就明白了
