ASTM A871 / A871M steel

The ASTM A871 specification is the standard specification for high-strength low-alloy structural steel plates with atmospheric corrosion resistance used in tubular structures and poles. Grades 60 and 65 are available in the as-rolled, normalized, or quenched and tempered delivery conditions as required to achieve the specified mechanical properties.

The specifications:
Thickness: 3mm--150mm
Width: 30mm--4000mm
Length: 1000mm--12000mm
Standard: ASTM EN10025 JIS GB

A871 Grade 65 may be provided as-rolled, normalized or quenched and tempered.
