The features and advantages of HIC ASTM A516 gr 70 plate

HIC ASTM A516 gr 70 plate is a kind of anti hydrogen sulfide corrosion steel plate, mainly used in petrochemical manufacturing industry. HIC ASTM A516 gr 70 plate has a lot of features and advantages. Such as:

1. HIC ASTM A516 gr 70 plate has low P and S content, high purity and good corrosion resistance to wet hydrogen sulfide.

2. The low temperature toughness of HIC ASTM A516 gr 70 plate is good, and HIC ASTM A516 gr 70 plate with the thickness of more than 100mm can protect 1 / 2 of the thickness of the plate from transverse impact of - 30 degree;

3. The thickest specification of our HIC ASTM A516 gr 70 plate reaches 176mm, and we can guarantee the Z35 performance in the thickness direction.

4. Hydrogen induced crack (HIC) resistance test method shall be in accordance with NACE TM0284 or GB8650 standard. The average value of three samples is CLR ≤ 10%, CSR ≤ 3%, CTR ≤ 1%.
CLR: crack length percentage; CSR: crack sensitivity percentage; CTR: crack thickness percentage;

5. Excellent resistance to sulfide stress corrosion (SSCC);

6. The hardness of HIC ASTM A516 gr 70 plate surface is controllable, the HIC ASTM A516 gr 70 plate has good machinability and is easy to roll.
