* Ca value for reference only, do not make acceptance conditions, Ca O content analysis can be used instead of finished product value melting analysis value.
* * carbon equivalent (CE) computation formula is as follows: CE = C + Mn / 6
* * * S content of the target of 0.002%
4. Delivery status: normalized
5. Mechanical properties and process performance
5.1 sample simulation of heat treatment after welding after stretching, impact, bending test results should comply with the provisions of the table 2. Quartile 24 mm steel plate thickness, and its thickness direction performance also should be consistent with the GB/T5313-1985 in the provisions of the Z35 level.
5.2 brinell hardness
Steel should be finished by piece brinell hardness testing, brinell hardness value ≤200 HB
