low alloy high strength steels with satisfactory mechanical properties and cracking resistance,it is necessary for weld metal to obtain high volume fraction of acicular ferrite.Fine acicular ferrite containing high density of dislocations is the expected microstructure in weld metal.High-angle bound-GB carbon and low alloy steel--3m X 6m X 150mm Q550CGB carbon and low alloy steel--The boiler steel plate is used to manufacture various boilers and important accessories.Because the Q550C steel sheet boiler steel plate works under the medium temperature (below 350 ° C) and higGB carbon and low alloy steel--Q550C L shaped steel angle Chromium element (Cr element) can improve the strength and hardness of Q550C L shaped steel angle,carbon steel in rolling state,reduce elongation and area reduction.When the chromium content is more than 15%,the strength and hardness will decrease,while the elongation and reduction of area will increase correspondingly.
