1. The main technical requirements

1.1 brand and chemical composition

Steel grades and chemical composition (melting analysis) should be in accordance with table 1.

Chart 1            wt％

Note: Pcm for welding crack sensitive components, Pcm computation formula is as follows:

Pcm = C + Si / 30 + Mn / 20 + Cu / 20 + Ni / 60 + Cr / 20 + Mo / 15 + V / 10 + 5 B

1.2 the mechanical properties of the steel plate should comply with the provisions in table 2.
