Testing of Welded Joints of Gas-Tight Pipe Walls Made of New Generation Martensitic Steel Type VM12-SHC

Abstract:

The paper presents the results of macro and microstructure testing and of hardness measurements of submerged arc welded joints of VM12SHC steel pipes (special high corrosion resistance, X12CrCoWVNbN12-2-2) with flat bars made of 10CrMo910 steel, intended for operation in elevated temperature. The tests were performed on welded joints that were not heat-treated and welded joints that were annealed (at 735-745°C for 0.5 hours) after welding. The results of the tests were used as a base to elaborate a Welding Procedure Specification.
