ASTM A871 Weathering Steel, A871MGr65 American Standard Weathering Steel, ASTM A871M Grade 60 Type I

ASTM A871 Weathering Steel, A871MGr65 American Standard Weathering Steel, ASTM A871M Grade 60 Type I

ASTM A871 is the American standard weathering steel plate, ASTM A871 is intended for pipe structures and supports or other suitable applications of high-strength low-alloy steel plate, in order to meet the specified mechanical property requirements, it is divided into two grades Gr60 and Gr65, which can be hot-rolled, normalized or quenched plus tempered.

Gr65 with a thickness of 5-20 mm and Gr60 with a thickness of 5 to 35 mm are usually supplied in a hot-rolled state. In order to meet the requirements of mechanical properties, the manufacturer has the freedom to choose the heat treatment of the material, the material should be heated to no less than 900 degrees for quenching and heat recovery treatment, and the material should be heated evenly for sufficient time to heat up, and then quenched in a suitable medium, and then tempered at no less than 595 degrees. The heat treatment temperature should be reported in the test certificate. The thickness grade of the steel plate is only limited by the composition to meet the specified mechanical properties, and the actual thickness under each steel grade and heat treatment method should be determined in contact with the individual manufacturer.

ASTM A871 steel plate is the grade of American standard weathering board, and the yield strength of the national standard Q460NH is the same, but the chemical composition is different.

In mild steel or carbon steel, microalloying elements such as niobium, titanium, vanadium and other microalloying elements are added alone or in combination to form carbon and nitrogen compound particles for strengthening, and at the same time, through the fine grain action of microalloying elements to obtain higher strength.

ASTMA871Gr65 weathering steel can be painted, bare or stabilized when used, and the requirements for coating are the same as ordinary carbon steel. In particular, it should be pointed out here that this material can be used without painting, which is the outstanding advantage of weathering steel. In areas where there is no serious air pollution or non-particularly humid, weathering steel can be directly in the atmosphere without coating, generally after a period of years, the rust layer gradually stabilizes, corrosion no longer develops, and the appearance is a beautiful chocolate color. This kind of steel knot does not need to be coated and maintained because there is no problem such as paint aging, which greatly reduces the maintenance cost, and of course avoids the loss caused by the impact of painting. Because of its unique color, weathering steel is used as a building façade by many people! Its own characteristics can greatly slow down the corrosion rate of steel plates, making the building easier to maintain, painting-free, and more environmentally friendly in the later use process. It can never fade.

The combination of ASTMA871Gr65 weathering steel and anticorrosive wood and rubble, rough and delicate, cold and warm, soft and hard. Why does a rusty steel plate create such a rich design context? This is due to the material's unique expressive properties.
