Q370qENH-Z15 Q370qENH-Z25 Q370qENH-Z35 weathering bridge steel plate

Q370qENH-Z15, Q370qENH-Z25, Q370qENH-Z35 belong to low-alloy high-strength steel, the grade of bridge steel, Q - the “yield” character of the yield point of bridge steel; 370 - yield point value, in Mpa; q - bridge; C, D, E - quality grades. Q370qCNH/Q370qDNH/Q370qENH steel can increase technical requirements: flaw detection, Z15-Z25-Z35 thickness direction performance requirements, high strength and high toughness requirements, etc.

Q370qENH-Z15, Q370qENH-Z25, Q370qENH-Z35 steel plate implement technical standards: GB/T 714 structural steel for bridges, widely used in buildings and bridges, for the production of riveted and bolt-welded highway bridges and railway bridges ( including cross-sea bridge).

Q370qENH-Z15, Q370qENH-Z25, Q370qENH-Z35 weathering bridge steel plate heat treatment description: hot rolling, normalizing, TMCP condition (Z-direction performance, flaw detection can be required)
