ASTM A588 Weathering Steel Plates Supplier in China

A588 Weathering Structural Steel

1. Basic information

A588 Grade Standard ASTM A588/A588M-2015 Atmospheric Corrosion Resistance High Strength Low Alloy Structural Steel Material Category Weathering Steel, Low Alloy High Strength Steel Products Hot Rolled Sheet Use Construction and Bridge

A588GrB, A588GrA, A588GrC manufacturing plants are used for general construction and various construction machinery.

2. Introduction

A588GrB, A588GrA, A588GrC manufacturing plants, general construction and various construction machinery, such as drilling rigs, electric shovels, electric wheel dump trucks, mining vehicles, excavators, loaders, bulldozers, various types of cranes for mining and various engineering construction , Coal mine hydraulic support and other mechanical equipment and other structural parts. 8mm~200mm thick A588 series high weathering bridge structural steel plates include A588GrA, A588GrB, etc. This type of steel forms a protective layer on the surface of the metal substrate through the alloying of Cu, P, Cr, Ni, etc., so that it has high atmospheric corrosion resistance. This type of steel is widely used in various weather-resistant building structural parts (especially for industrial atmospheric environments), bridge auxiliary structural parts, etc.

3. Chemical composition (wt%)

CSiMnPSNiCrCuV≤0.190.3~0.650.8~1.25≤0.03≤0.03≤0.40.4~0.650.25~0.40.02~0.1

Ingredient Note: For every 0.01 decrease in the maximum C, the maximum Mn is allowed to increase by 0.06, up to a maximum of 1.5.

4. What material is A588

A protective layer is formed on the surface of the metal substrate, so that it has high atmospheric corrosion resistance. A588 low-alloy high-strength steel plate includes A588GrA, A588GrB, A588GrC, which are used for manufacturing workshops, general buildings and various construction machinery, such as mines and various Drilling rigs, electric shovels, electric wheel dump trucks, mining vehicles, excavators, loaders, bulldozers, various cranes, coal mine hydraulic supports and other mechanical equipment and other structural parts for engineering construction. 8mm~200mm thick A588 series high weathering bridge structural steel plates include A588GrA, A588GrB, etc. This type of steel forms a protective layer on the surface of the metal substrate through the alloying of Cu, P, Cr, Ni, etc., so that it has high atmospheric corrosion resistance. This type of steel is widely used in various weather-resistant building structural parts (especially for industrial atmospheric environments), bridge auxiliary structural parts, etc.
