What is ISO/TR 14745 - Post-weld heat treatment parameters for steels about?
ISO/TR 14745 is a technical report on welding that discusses post-weld heat treatment parameters for steels for post-weld heat treatment (PWHT) to alleviate residual stresses .
ISO/TR 14745 specifies recommendations for post-weld heat treatment (PWHT) of steels with recommendations for holding temperatures and holding times for different materials and material thicknesses.
The recommendations under ISO/TR 14745 are limited and beneficial to stress-relieving for non-alloy steels and tempering for Cr-Mo-(Ni) steels and martensitic stainless steels, and are independent of the type of product or location.
Note: ISO/TR 14745 does not specify when PWHT is required. Such requirements are given in product standards, material specifications, or material datasheets.
Who is ISO/TR 14745 - Post-weld heat treatment parameters for steels for?
ISO/TR 14745 on the post-weld heat treatment parameters for steels is relevant to:
- Welding industry
- Steel products manufacturers
Why should you use ISO/TR 14745 - Post-weld heat treatment parameters for steels?
Post-weld heat treatment is a process that involves elevating the temperature of a material or materials following a welding process.
ISO/TR 14745 assists by assisting non-alloy steels but are limited and beneficial to alleviate residual stresses, increase the strength, increase or decrease the hardness, and reduce the risk of cracking.
ISO/TR 14745 assists by providing recommendations for post-weld heat treatment for steels to reduce the risk of hydrogen cracking of steel and increase the ductility of the steel.
With compliance and obedience to ISO/TR 14745, you can enhance the efficacy of steel and enhance the ductility of steel.
