1.Introduction of A588GrA Steel Plate

A588GrA, A588GrB, A588GrC Weathering steels with atmospheric corrosion resistance, high strength and low alloy structural steels with [TJC STEEL.]minimum yield point of 345MPa, low alloy high strength steel products hot-rolled sheet for building and bridge manufacturing workshops for general construction and various construction machinery.

 

2.Chemical composition of A588GrA Weather Resistant Steel Plate:

C≤0.19 Si: 0.3~0.65 Mn: 0.8~1.25 P≤0.03 S≤0.03 Ni≤0.4

Cr: 0.4~0.65 Cu: 0.25~ 0.4V: 0.02~0.1

 

3.Mechanical Properties of A588GrA Steel Plate:

A-plate (≤100) hot rolled ≤100 [TJC STEEL.]A588 Gr. A-plate (>100~125) plate >100~125 A588 Gr. A-plate (>125~200)>125~200

Re(MPa)≥345 means Rm(MPa)≥485 means A50(%)≥21 means A200≥18%

Re(MPa)≥345 means Rm(MPa)≥485 means A50(%)≥21 means A200≥18%

Re(MPa)≥315 means Rm(MPa)≥460 means A50(%)≥21 means

Re(MPa)≥290 means Rm(MPa)≥435 means A50(%)≥21 means

 

4.Application Scenario of A588GrA Steel Plate:

Form a protective layer on [TJC STEEL.]the metal substrate surface, thus has the high resistance to atmospheric corrosion performance, A588 high strength low alloy steel including A588GrA, A588GrB, A588GrC, used in the manufacture of workshop, general construction and all kinds of engineering machinery, such as mining and all kinds of engineering construction in the drill, excavator, electric wheel dump truck, mine car, excavators, loaders, bulldozers, cranes, hydraulic support in coal mine and other mechanical equipment and other structures.A588 series high weathering steel plate of bridge structure with thickness of 8mm ~ 200mm includes A588GrA, A588GrB, etc.This type of steel is alloyed by Cu, P, Cr, Ni and so on to form a protective layer on the surface of the metal substrate, so as to have a higher atmospheric corrosion resistance.This kind of steel is widely used in[TJC STEEL.] various weather-resistant building structures (especially for industrial atmospheric environment), bridge auxiliary structures and other aspects.
