How to perform heat treatment processes
Thread Content
Composite plate coils require post-weld heat treatment. The material used is 20R+0Cr13, and the specifications for these coil pipes are φ168×(10+3), φ273×(9+3), and φ530×(12+3). How should the heat treatment process be established? This post was last edited by Lan Meng on 2009-3-3 08:51.]
Specific provisions for this material are given in the appendix to standard JB4709
You are referring to clause A8.3 in the appendix of standard JB4709, which deals with pressure vessels made of 0Cr13 stainless steel as the cladding layer. When austenitic stainless steel welding materials are used to weld the cladding layer and the base material, and no post-weld heat treatment is required, then such heat treatment can be omitted. Otherwise, post-weld heat treatment must be carried out in accordance with the requirements for the cladding material. I was unable to find the heat treatment temperature for 0Cr13
