Abstract
Bent steel pipe with good strength and low-temperature toughness is obtained by bending a steel pipe under the following conditions: heating temperature : from 900 to 1,150 DEG C, holding period : up to 15 minutes, and cooling rate : from 5 to 100 DEG C/second. The steel pipe comprises at least one layer of steel sheet having the composition: carbon : from 0.002 to 0.050 wt.,%, silicon : from 0.05 to 0.80 wt.%, manganese : from 0.80 to 2.20 wt.%, niobium : from 0.002 to 0.100 wt.%, aluminium : from 0.01 to 0.08 wt.%, and nitrogen : from 0.002 to 0.010 wt.%, the balance being iron and incidental impurities. Optionally the steel sheet further contains, as a strength-improving constituent, at least one element selected from: copper : from 0.05 to 1.00 wt.%, nickel : from 0.05 to 3.00 wt.%, chromium : from 0.05 to 1.00 wt.%, molybdenum : from 0.03 to 0.80 wt.%, vanadium : from 0.01 to 0.10 wt.%, boron : from 0.0003 to 0.0030 wt.%, titanium : from 0.005 to 0.100 wt.%, and calcium : from 0.0002 to 0.0100 wt.%. c
