15Mo3 STEEL PLATE

15Mo3,15Mo3 steel plate,15Mo3 steel sheet are mainly used for building boilers and pressure vessels.When rolling,15Mo3 contains more Mo elements than other steel grades in Din 17155,but lower than 13CrMo44 and 10CrMo910.For 15Mo3 boiler steel plate thickness belows and equal to 16millimeters,the minimum yield strength shall be 275Mpa,and tensile strength shall be within 440-590Mpa for thickness equal and belows 60millimeters of pressure vessel steel plate 15Mo3,boiler steel plate 15Mo3 is equal to boiler steel grade 16Mo3 when supplied.
