Pwosesis tretman chalè nan tiyo duplex asye pur se kritik amelyore pèfòmans li yo . anjeneral, pwosesis la tretman chalè nan tiyo duplex asye pur gen ladan tretman solisyon ak tretman sansibilizasyon .
Solution treatment is to heat the duplex stainless steel pipe to a high temperature to fully dissolve the ferrite and austenite phases and then quickly cool it to obtain a uniform duplex structure. The temperature of solution treatment is generally between 1050 and 1150. The cooling method can be water quenching or air cooling. Solution treatment can improve the corrosion resistance, toughness and strength of duplex tiyo asye pur ak amelyore pèfòmans pwosesis li yo .
Tretman sansibilizasyon se chofe tiyo a duplex asye pur nan yon tanperati sèten epi kenbe li nan tanperati sa a pou yon peryòd de tan ak Lè sa a, byen vit fre li {{0} 950 detèmine pa materyèl espesifik ak kondisyon .
In the actual heat treatment process, it is necessary to reasonably select heat treatment process parameters based on the specific material size and use requirements of the duplex stainless steel pipe to ensure the stability and reliability of the heat treatment effect. At the same time, it is also necessary to pay attention to issues such as temperature uniformity and cooling speed during the heat treatment process to avoid heat treatment defects such as intergranular corrosion deformation, elatriye .
