摘要

通过对月亮湾燃机电厂 3号燃机进气安全隔离滤网失效的不锈钢钢丝进行无损检测和其化学成分、金相、能谱以及断口分析等

确定不锈钢钢丝合金比例不当、锰含量太高且晶间析出碳化物 ;材质存在严重质量问题。建议钢丝材料选用超低碳、铬镍含量高、含钼 2 %～ 3 %的 0 0Cr1 7Ni1 4Mo3或 3 1 6L( 0 0Cr1 7Ni1 4Mo2 )奥氏体不锈钢

且制造应符合GB 4 2 4 0要求

Abstract

Throung tests of non-destructive detection

analysis of chemical composition

metallurgy

energy spectrum

and fractures for the failed reinforcing wires of incoming gas safety isolating strainer on gas turbine No.3 in Yueliangwan Gas Tubine Power Plant

it is determined that one cause leading to early fracture is unsuitable proportion of alloy composition for the stainless wires

the content of mangonese being high

eduction of intergranular carbide

as well as sirious quality problems existing in the material used. It is recommended to select OOCr 17 Ni14 Mo3 or 316L (OOCr17N:14MoZ) austenitic stainless steel having ultta-low carbon content

high Cr and Ni content

and 2%～3%Mo content

and the fabrication of reinforcing wires having to be in conformity with requirements of standard GB4240.
