The steel stamp of the material?
Thread Content
Stamping is not allowed on fatigue containers. I was wondering if it’s possible to purchase materials that do not have stamps on them If that doesn’t work, then how should the steel stamp on the material be removed during manufacturing?
:The steel stamps mentioned here generally refer to welder’s stamps and marking stamps used during material transfer. A material factory would never use this method for marking.
Steel mill materials do not have steel stamps on the raw materials at the time of production.
Stamping is not allowed, and the material must be free of surface defects such as deep scratches and pits
It’s on the plates, I think; stainless steel ones don’t seem to have it. You don’t need to include the stamp; in other words, you can remove the one with the stamp. If this cannot be done, I think it can only be smoothly removed, but not to a thickness less than its designed thickness.
New Specification 2.1 clearly stipulates that material manufacturers must apply clear and durable stamp marks in prominent locations on the materials, or use other marking methods. In practice, the steel plates produced by manufacturers usually have markings applied to them, but forgings all come with steel stamps
Material factories generally do not stamp this mark; they usually provide product instructions instead.
Steel plates leaving the steel mill are usually marked with spray-painted text indicating the applicable standards, furnace batch number, specifications, and thickness, while forgings produced by manufacturing companies are mostly marked with steel stamps.
Carbon steel container plates – the genuine ones all have steel stamps. During manufacturing, the stamping position on the material can be avoided. Stainless steel plates are generally spray-painted. Additionally, it can be specified in the purchase contract that there must be no steel stamps on the steel plates, as a condition of purchase.
Some have stamping, but this is not the case for special materials; usually, labeling by spraying or attaching tags is used instead
