1. Cov ntaub ntawv tseem ceeb ntawm A588GrA:
Qib A588 Standard ASTM A588/A588M -2015 Atmospheric corrosion kuj nrog yam tsawg kawg nkaus yield point 345MPa High-strength low-alloy structural steel Khoom qeb Weathering steel, low-alloy high-strength steel khoom Kub dov daim hlau Siv rau kev tsim kho thiab txuas hniav A588GrB, A588GrA, A588GrC Manufacturing nroj tsuag, siv nyob rau hauv dav siv thiab ntau hom kev siv machinery.
2. Tshuaj muaj pes tsawg leeg ntawm A588GrA weathering steel phaj:
C Tsawg dua lossis sib npaug rau {{0}}.19 Si: 0.3 ~ 0.65 Mn: {{10}}.8 ~ 1.25 P Less dua lossis sib npaug rau 0.03 S Tsawg dua lossis sib npaug rau 0.03 Ni Tsawg dua lossis sib npaug rau 0.4
Cr: {{0}.4~{4}}.65 Cu: 0.25~{8}}.4 V: 0.02~0.1
4. A588GrA steel phaj daim ntawv thov scenarios:
Ib txheej tiv thaiv yog tsim rau saum npoo ntawm cov hlau substrate, yog li muaj kev tiv thaiv siab rau atmospheric corrosion. A588 low-alloy high-strength steel phaj muaj xws li A588GrA, A588GrB, thiab A588GrC. Lawv tau siv rau hauv kev tsim cov nroj tsuag, kev tsim kho dav dav thiab ntau hom engineering machinery, xws li mining thiab ntau hom engineering machinery. Drilling rigs, hluav taws xob shovels, hluav taws xob log tsheb thauj khoom, tsheb mining, excavators, loaders, bulldozers, ntau yam cranes, thee mine hydraulic txhawb nqa thiab lwm yam khoom siv tshuab thiab lwm yam khoom siv hauv kev tsim kho engineering. 8mm ~ 200mm tuab A588 series siab huab cua-resistant choj cov qauv hlau daim hlau muaj xws li A588GrA, A588GrB, thiab lwm yam. yog li muaj siab atmospheric corrosion kuj. Hom hlau no yog dav siv nyob rau hauv ntau yam huab cua-resistant lub tsev structural qhov chaw (tshwj xeeb tshaj yog nyob rau hauv industrial atmospheric ib puag ncig), choj auxiliary structural qhov chaw, thiab lwm yam.
