Document Type and Number:
WIPO Patent Application WO/2020/093687
Kind Code:
A1
Abstract:
Disclosed is composite seismic resistant fire retardant steel for construction, and the chemical composition thereof, by weight percentage, is: C: 0.08-0.16%, Si: 0.15-0.55%, Mn: 0.50-1.80%, Mo: 0.10-0.50%, Nb: 0.02-0.15%, V: 0.00-0.12%, Ti: 0.01-0.020%, and the balance being Fe and inevitable impurities. The composite seismic resistant fire retardant steel for construction designed in the present invention and the preparation method thereof can reduce costs of using an alloy, have composite properties such as high strength and toughness, seismic resistance and intelligent fire retardant performance, and resistance to large line energy welding.
