ASTM A633 Gr E alloy steel quality

A633 Gr E under ASTM A633 specification is a high-strength low alloy steel quality. As a leading supplier of carbon steel and alloy steel plate in China, our company will supply high quality A633 Gr E plate and deep processing service like cutting, drilling, welding, milling and beveling. Our ASTM A633 Gr E alloy can be used for service at low ambient temperatures of -50℉[-45℃] and higher where notch toughness better that expected in as-rolled material of a comparable strength level is desired.
A633 Gr E plate size: Grade E alloy steel plate can be produced with thickness to 150mm.
