Effect of Stainless Steel Weld Overlay Deposit on the Hardness of API 5L Pipes
: To improve the corrosion resistance of API 5 L pipe, we applied a weld overlay of UNS S31603 stainless steel as filler metal. To confirm the modified material’s quality, we determine the hardness of the material to be compared to API 5LD specification. We performed Vickers hardness tests at the corrosion-resistant alloy (CRA) area and the base metal and heat-affected zone. The tests show that the deposition improves the material hardness by 7.32%. The average Vickers hardness number at the CRA area was 212.32 HV, with 230 HV. Referring to API 5LD qualification, the maximum hardness allowed at the CRA area is 300 HV. Thus, the material processed by weld overlay has an acceptable quality.
