为了满足石油化工对低温用钢的要求,冶金工业部门发展了一些立足于国内资源的无镍铬低温用钢。从目前石油化工工艺流程来说,用量较大的是一110℃以上的各类低温用钢。现有适用于此温度范围的低温用钢一般都
In order to meet the petrochemical requirements for low temperature steel, the metallurgical industry has developed some non-nickel-chromium low-temperature steel based on domestic resources. From the current petrochemical process, the larger amount of a 110 ℃ above all kinds of low temperature steel. The existing low-temperature steel for this temperature range are generally
