Abstract
In order to successfully develop X90 Φ1 219 mm×26.4 mm high strength steel hot bending bends, it analyzed the raw material of X90 main pipe. The trial-manufacture of hot bending bends, mechanical properties test and microstructure contrastive analysis were carried out by adopting different heating methods, the microstructure and properties of X90 hot bending bends produced by two heating methods were studied. The entire heating method(1 000℃heating temperature, 560℃tempering temperature) was optimum selection. The microstructure performance of trial-manufacture hot bending bends achieved the optimal state, and accorded with API SPEC 5L—2009 and SY/T 5257—2012 standard requirement.关键词
