【Abstract】 This paper introduces the standard and current situation on aluminium killed steel and pre-low-temperature nickel steel for petrochemical equipment in low temperature condition at home and abroad. It also analyses the devoloping tendency of low temperature steel in foreign countries. Finally, it sumarises the reasons of not widely using of low temperature aluminium killed steel in our country and points out the significance on devoloping our production of pre-low-temperature nickel steel.更多还原
