British worry about high alloy content of steel from China would harm for steel welding performance

British Steel Association recently issued a safety warning that steel plate and profile steel imported from China are not in line with European standards. Allegedly steel plate imported from China now is being investigated under the supervision of Eurofer.

British Steel Association noted that the boron content of these steel plates is greater than 0.0008%.or chromium content greater than 0.3% or copper content greater than 0.55%, which all not in line with European standards. Long before the end of last year, the British Steel Corporation, pointed out that the steel adding more boron can lead to cracking when welding, which causing great concern of Eurofer, the British government also said it would strengthen the import inspection review. British Steel said boron content may damage steel performance, the welding heat affected zone (HAZ) cracking Similarly, chromium content of more than 0.3% had a similar situation, greatly increasing the genarate of crack HAZ, copper content exceeding 0.4% may also cause weld fracture. British Steel Association recommends users carefully checked alloy content importing from China before welding.
