Q355NBZ15 low-alloy steel plate performance analysis and thick plate supply
I. Introduction to Q355NBZ15 steel plate: 1.
Introduction
to Q355NBZ15 steel plate Q355NBZ15 is a kind of low-alloy high-strength structural steel. Q355NBZ15 is not only high-strength steel, it is also low-carbon steel. Q355NBZ15 has high yield strength and fatigue resistance; High toughness and low brittle transition temperature; ** Cold forming properties and welding properties; It has good corrosion resistance and certain wear resistance.
2. Q355NBZ15 steel plate implementation standard: GB/T1591-2018.
3. Q355NBZ15 the delivery status of the steel plate: normalized or normalized rolled
4. Q355NBZ15 When the thickness direction performance of the steel plate is required to have the thickness direction performance, the symbols Z15, Z25 and Z35 representing the thickness direction performance
level are added after the grades specified above.
5. Q355NBZ15 steel plate smelting method:
the steel is smelted by converter or electric furnace, and the extraction outside the furnace can be carried out if necessary. Unless the buyer has special requirements and indicates in the contract, the smelting method is generally chosen by the supplier.
