What does "Z" mean to the performance of steel?
To apply for Z steel plate thickness and subjected to tensile load on just the thickness direction has the performance requirements, it is in a certain level of structural steel (called parent steel) on the basis of the special treatment (such as calcium treatment, vacuum degassing, argon stirring etc.) and proper heat treatment steel.
The Z plate is used to prevent lamellar tearing of plates, the main connections at the plate, if the plates in the thickness direction bear significant tensile stress on the sheet.
Hello, I do steel plate, Z to the performance, that is, the thickness of the direction of tension, if the steel plate is greater than 40Mm, the stress position of the steel plate thickness direction, then you have to Z performance! Don't forget the purchase list, brother. Contact information!
Z to the plate, also known as "Z" to steel, also known as "lamellar steel tearing resistant steel", that is usually referred to as Z performance.The use of welded connections in steel structure, when the sheet thickness of not less than 40 mm and bear along the thickness direction of the tension, to avoid lamellar tearing when welding, the lamellar tearing of steel (commonly referred to as the "Z to steel"). There is a lamellar tearing problem in thick plates, so Z performance test is necessary.
