Characteristics of A515 Gr 65 pressure vessel steel sheet production

The A515 Gr 65 pressure vessel steel sheet, wear-resistant steel plate has good impact properties:
The wear-resistant steel plate has a double-layer metal structure. The wear-resistant layer and the base material are metallurgically bonded. It has high bonding strength and can absorb energy in the process of impact. The wear-resistant layer will not fall off. The wear-resistant steel plate can be applied to the working conditions with strong vibration and impact, which is better than cast wear-resistant materials and ceramic materials.

Titanium microalloying is an element of A515 Gr 65 pressure vessel steel sheet strengthening complex with carbon and nitrogen. The addition of micro amount of titanium in the steel can fix almost all nitrogen and part carbon in the steel, so as to eliminate the strain aging phenomenon and improve the aging impact performance of the steel. At the same time, it can refine the grains and change the morphology of the compounds. According to the atomic weight ratio of Ti and N in A515 Gr 65 pressure vessel steel sheet tin formula (Ti = 3.4n), the content of Ti in steel should be controlled between 0.015 and 0.025%. Generally, the amount of ferrotitanium added to each ton of steel is 1kg.
