Abstract

MAYARI R is a low-alloy, high-strength steel having excellent resistance to atmospheric corrosion, high yield point and superior weldability. It may be fabricated with regular shop equipment used for structural-grade carbon steel. It is used widely as a weathering steel in architectural work. This datasheet provides information on composition, physical properties, hardness, elasticity, and tensile properties. It also includes information on high temperature performance and corrosion resistance as well as forming, heat treating, machining, and joining. Filing Code: SA-20. Producer or source: Bethlehem Steel Corporation. Originally published June 1954, revised November 1971.
