This Technical Report provides recommendations for post-weld heat treatment (PWHT) of steels with
recommendations for holding temperatures and holding times for different materials and material thicknesses.
These recommendations are limited to stress relieving and are independent of type of product or location.
The recommendations do not supersede any guidance given in material supplier specifications, e.g.
thermomechanically treated fine-grain steels.
This Technical Report does not specify when PWHT is required. Such requirements are given in product
standards, material specifications or material data sheets.
