It is known that yield strength, tensile strength and elongation of HP295 steel plate meet the requirements of GB6653-2008.The yield strength, tensile strength and elongation of HP295 steel plate produced by Katalor are 343-427mpa, 471-529mpa and 25%~32% respectively.
The buckling strength ratio is one of the important properties of HP295 steel plate. Since the quality of cylinder made of HP295 steel plate is directly related to the safety of people’s life and property, it is necessary to carry out the random inspection of the cylinder and conduct the hydraulic blasting test. It is required that after the hydraulic blasting test, the HP295 steel plate cylinder has a lower ratio of buckling to strength and a higher volume deformation rate.
The main factors that affect the maximum buckling ratio of HP295 steel plate is composition, ferrite grain size, rolling temperature and cooling strength. Through design and production control of HP295 steel plate composition, finishing and coil-up temperature, ferrite grain size reaches grade 10 (national standard requires grade 6 or above), the purpose of reducing the buckling strength ratio is achieved, and the buckling strength ratio of HP295 steel plate is controlled within 0.70~0.80.
