10CrMoAl is a kind of special steel for resisting seawater corrosion. 10CrMoAl material is the most ideal pipeline and processing material for coastal power plants, offshore oil fields, coastal natural gas and petrochemical plants to transport water, oil, gas and sea water medium. It can also be used to make the valve flange

Corrosion resistance:

1, 10CrMoAl material Al (aluminum), and O (oxygen) in the air chemical reaction to produce Al2O3 (three oxidation two aluminum). From the line into protective film, both anti-corrosion and corrosion resistance.

2, 10CrMoAl Cr (CR), Mo (MO), can automatically add the Cl ion in seawater (CL) ions on the corrosion of steel space form, into a dense protective layer, prevent corrosion to develop in depth. And then corrosion resistance, so that longer service life.

Welding:

10CrMoAl material welding performance is good, equipped with special corrosion-resistant electrode "sea O3", without special welding requirements.

10CrMoAL density: 7.85 t/m3

Delivery status

3. less than 30mm thickness, tempering or normalizing + tempering. Thickness > 30mm, normalizing + tempering. The status of the specific delivery is stated in the contract.

4. by the requirements of the buyer and noted in the contract, the steel plate can also be hot-rolled delivery. Under hot rolling condition, the steel plate is responsible for the adaptability of the processing technology.

5. inspection rules 5.1 plate according to the batch test, each batch from the same furnace, the same thickness, the same delivery state of the steel plate, the plate thickness is less than 16mm, the weight of each batch of not more than 15 tons; plate thickness is more than 16mm, the weight of each batch of not more than 30 tons. 5.2 steel Charpy (V gap) impact test results do not meet the requirements, from the same batch of steel plate and a group of three specimens. The average value of the six specimens before and after shall not be lower than the value specified in Table 2, allowing only two of the specimens to be below the specified value, but only one of the specimens below the prescribed value of 70%. 6 the reinspection, packing, marking and quality certificate conform to the requirements of GB/T247-1997.
