摘要

试验和测试了900-1 300℃固溶处理时双相不锈钢00Cr25Ni7Mo4N的相组成、冲击能AKV和硬度(HRC)值。试验结果表明

在900-1 020℃固溶处理时

双相不锈钢中有16．97％-3．22％σ相析出

使钢的冲击能A

值从1 040-1 250℃处理的224～280 J降至3～44 J。该双相不锈钢的热加工温度应大于1 040℃

其最佳固溶处理温度为1 040～1 100℃。

Abstract

The phase composition

impact energy A

and hardness HRC value of duplex stainless steel 00Cr25Ni7Mo4N solution treated at 900~1300 ℃ have been studied and examined. The results showed that 16.97%~ 3.22% a- phase precipitated in duplex stainless steel during solution treatment at 900~1020 ℃ led to the impact energy Agy value of steel decreasing to 3~44 J from 224~280 Jwhile steel treated at 1040~1250 ℃. The hot work temperature of the duplex stainless steel should be higher than 1040 ℃ and its optimum solution treatment temperature is 1040～1100 ℃.
