SA588 Qib K siab zog steel ntawv

High Strength Steel Sheet (HSLA) Cov Khoom Piav Qhia

SA588GrK siab zog alloy steel yog lub siab-lub zog qis alloy qauv steel phaj haum rau welded, riveted los yog bolted lug nrog atmospheric corrosion kuj.

SA588GrK lub zog siab steel yog qhov muaj zog tiv taus ntau dua rau atmospheric corrosion dua li carbon structural steel nrog lossis tsis muaj tooj liab nyob rau hauv feem ntau ib puag ncig. Thaum tag nrho raug rau cov huab cua, SA588GrK tsis tshua muaj hlau alloy yog tsim rau ntau daim ntawv thov nyob rau hauv nws liab qab (uncoated) lub xeev.
