A653 steel

A653 steel has a wide range of uses, so why is it so popular? The reason is mainly due to the galvanizing layer and zinc content, which give it excellent corrosion resistance. It is a high-strength, low-alloy steel. Therefore, they are often used in outdoor hardware such as outdoor signs, trash cans, heating and cooling systems, and electrical protection. The ASTM A653 standard is used worldwide to ensure that the steel produced meets certain quality requirements and has consistency and reliability.

A653 steel Scope of the Standard

1. The ASTM A653 standard covers hot-dip galvanized pure zinc and zinc-iron alloy-coated steel strips delivered in coils or as cut-to-length products.

2. The standard specifies requirements for the chemical composition, mechanical properties, physical properties, and processing properties of hot-dip galvanized steel sheets and strips.

What is A653 steel?

It is a standard developed by the ASTM ( American Society for Testing and Materials ) to evaluate the quality of hot-dip galvanized steel sheets and strips. A-653 is one of the ASTM branch standard numbers. The standard for hot-dipped galvanized iron alloy or galvanized steel sheet is ASTM A653.

Types Of A653 Steel 

A653 Steel Galvanized Sheet is available in metallurgical designations, providing different degrees of formability and strength to the base sheet:

Types
Commercial steel CS ( CSA, CSB, CSC )
Forming steel FS ( FSA, FSB )
Deep drawing steel DDS ( DDSA, DDSC )
Extra deep drawing steel EDDS
Structural steel SS
High strength low alloy steel HSLAS (HSLAS Type A,B,F)
Solution hardened steel SHS
Bake hardenable steel BHS

ASTM A653 steel equivalent

ASTM-A653 is an American standard, which is equivalent to the Japanese JIS G 3302, Europe EN 10346. It remains a hot-dip galvanized steel sheet with a coating thickness of 0.3 oz/square inch. The material has general specifications.

big-spangle

regular-spangle-surface

The American standard is special. There are both metric weight units (g/m2) such as Z90 and British weight units (oz/ft2) such as G90. The weight difference between the two is about 3 times.

Zero-Spangle-GI-Coils

What is ASTM A653 G90 specification

For example, ASTM A653 G90 is equivalent to the ASTM A653 specification, and “G90” refers to the galvanized layer. G90 represents the meaning that the sum of the two-sided zinc coating is 0.9 oz/ft2 (the average minimum value of three points on both sides) or 0.8 oz/ft2 (the smallest single point on both sides) value.

Thick galvanized hot-dip galvanized materials
Corrosion resistance is strong in thick galvanized hot-dip galvanized materials. By selecting spangles and post-processing functions, you can employ a variety of applications.

Hot-dip alloy steel
Hot-dip alloy steel has strong corrosion resistance, excellent coating adhesion, and ductility, which make it perform well during processing. It has the advantage of having a lovely appearance and being able to be employed in applications where the surface is not painted.
