RESEARCH ON MANUFACTURE AND QUALITY CONTROL OF MEDIUM CARBON VESSELS FOR RESISTANCE TO HYDROGEN INDUCED CRACKING
With the exploitation of gas mixed with sulfur,the requirement of hydrogen induced cracking(HIC)resistance for medium carbon vessels serving at environmental with hydrogen sulfide solution become more rigorous.Through the research on HIC,the formation reasons of those are: MnS inclusions,Al2O3 inclusions,P segregation,Bainites and Macro segregation of slab.Thus if these parameters are controlled appropriately,the qualified medium carbon vessels for resistance to HIC steel will be produced.The conclusions are following: the controlled measurements to cleanliness on liquid steel,macro segregation controlled on slab,large reduction at rolling and normalizing are used to produce the HIC resistance vessels.The properties of tensile strength and low temperature impact meet the standard properly.Meanwhile there aren”t hydrogen induced cracking found in any samples.
