Duplex Stainless Steel 2605N Soild Round Bar CD4MCu 0Cr26Ni5Mo2Cu3 Dimensions: 100x1000MM

Introduction

CD4MCu duplex stainless steel is classified according to its chemical composition and can be divided into four types: Cr18 type, Cr23 (excluding Mo) type, Cr22 type and Cr25 type. For Cr25 duplex stainless steel, it can be divided into common type and duplex stainless steel, among which Cr22 type and Cr25 type are more widely used.

Most of the duplex stainless steels used in my country are produced in Sweden, and the specific grades are: 3RE60 (Cr18 type), SAF2304 (Cr23 type), SAF2205 (Cr22 type), SAF2507 (Cr25 type). Alloy CD4MCu is nominally a 26Cr-6Ni alloy (C≤0.04) with additions of molybdenum and copper. There is no corresponding wrought steel grade for this alloy. Alloy CD4MCu has a dual-phase structure in the as-cast state, which is composed of austenite distributed in a ferrite matrix.

Although the carbide precipitation is limited by the carbon content of the alloy, if it is not eliminated by solution treatment, it will also be dispersed in the ferrite matrix, thereby reducing corrosion resistance. The solution treatment temperature of CD4MCu is 1120 ° C, and it should be kept for at least two hours , to ensure uniform temperature, slowly cool to 1010 ~ 1065 ºC, keep warm for half an hour, and then quench. Keeping warm at a lower temperature is to avoid cracking of castings (especially castings with thicker sections) during quenching. The structure after heat treatment is also duplex, containing 35 to 40% austenite in the ferrite matrix.

CD4MCu Corrosion Resistance
The pitting corrosion resistance of CD4MCu steel is better than other Cr18-5Mo duplex stainless steel, better than austenitic stainless steel 00Cr17Ni14Mo2.

CD4McuN material duplex stainless steel structure and type

CD4McuN material duplex stainless steel has the characteristics of austenitic stainless steel and ferritic stainless steel because it has austenite + ferrite duplex structure, and the content of the two phase structures is basically the same. The yield strength can reach 400Mpa ~ 550MPa, which is twice that of ordinary austenitic stainless steel. Compared with ferritic stainless steel, duplex stainless steel has high toughness, low brittle transition temperature, significantly improved intergranular corrosion resistance and welding performance; at the same time, it retains some characteristics of ferritic stainless steel, such as 475 ºC brittleness, thermal High conductivity, small coefficient of linear expansion, superplasticity and magnetism. Compared with austenitic stainless steel, the duplex stainless steel, especially the yield strength, is significantly improved, and the pitting corrosion resistance, stress corrosion resistance, fatigue and other properties are also obvious.

CD4McuN Duplex Stainless Steel Welding Characteristics

CD4McuN duplex stainless steel has good welding performance. Compared with ferritic stainless steel and austenitic stainless steel, it is neither like the welding heat-affected zone of ferritic stainless steel, but the plasticity and toughness are greatly reduced due to severe grain coarsening , and unlike austenitic stainless steel, it is more sensitive to welding hot cracks.

Welding performance problems often occur in economical "CD4McuN material duplex stainless steel". Welding standard duplex steels is not an issue, and there are consumables for these applications regardless of the process used. From a metallographic point of view, welding 2101 (1.4162) is no problem at all, in fact it is even easier to weld than standard grade duplex steel, because this material can actually be welded with acetylene welding, while This process is always avoided for standard duplex steel materials. The practical problem with welding 2101 is that the melt pool has a different viscosity and therefore is a little less wettable. This forces operators to use arc welding more and more during the welding process, which is where the problem lies. Although this can be remedied by selecting superalloyed consumables, we often wish to select matching consumables.
