Abrasion resistant steel plates NM550
NM550 steel plate grade introduction
NM550 steel plate grade in NM= wear-resistant is also wear-resistant initials pinyin abbreviation
NM550 steel plate grade 550= steel yield strength
Under the premise of ensuring the performance of NM550 wear-resistant steel plate, Cr, Ni, Mo alloying elements specified in Table 1 can be added in any combination, and other microalloying elements other than those specified in Table 1 can be added, and the specific content should be indicated in the quality certificate.
When Cu in NM550 wear-resistant steel plate is a residual element, its content should not be more than 0.30%; As content should not be greater than 0.08%. No analysis if the supplier can guarantee.
Third, NM550 steel plate chemical composition and alloy elements introduction
Alloying element carbon C<=0.25
Alloying element Si<=0.70
Alloying element manganese Mn<=1.60
Alloying element P <=0.025
Alloying element sulfur S<=0.010
Alloy element Mo<=0.50
Alloying element Chromium <=1.40.
Alloying element Boron B <=0.004
