Carbon content of ASTM A588 Grade A weathering steel

ASTM A588 Grade A weathering steel is a high-quality cold hardening steel that can be used to manufacture structural parts, especially suitable for making mechanical parts that are resistant to atmospheric corrosion, such as automobile shafts, gears and rolls.

Its carbon content is 0.35%~0.45%.

The main feature is that it has high yield strength and tensile strength, and can withstand large stress;

High hardenability, can maintain high strength at high temperature;

Phosphorus and sulfur added to the chemical composition can improve the hardenability of steel;

It has high resistance to temper embrittlement.

ASTM A588 Grade A weathering steel generally refers to those steels that are exposed to the atmosphere for a long time, but will not fade and rust.

ASTM A588 Grade A is a high-quality cold work hardened steel, which can be used in the manufacture of automobiles, train axles, gears and rolls.

Because its composition contains more phosphorus and sulfur, these elements combine with other elements in steel to form alloys, so steel has high strength and good toughness.

Steel will rust when exposed to the atmosphere for too long, and its corrosion products include carbides, sulfides, and oxides. Therefore, these steels are usually called weathering steels.

ASTM A588 Grade A weathering steel is an excellent steel material with better atmospheric corrosion resistance than ordinary low alloy steel.

As long as it is properly maintained and maintained during use, the weather resistance can be maintained for a long time.

In addition, because ASTM A588 Grade A steel has the characteristics of good hardenability and high tempering stability, it can also be used to manufacture various mechanical parts that require long service life and good wear resistance.
