ASTM A572 Gr.42/50/60/65 H beam steel

ASTM A572 Gr.42/50/60/65 H beam steel is a kind of high strength low alloy steel plate. it's standard is ASTM. A572 H beam is a high strength low alloy steel used in a variety of structural applications. A572 H beam is produced in Grades 42, 50, 60 & 65—the grades representing the yield strength. The most common grade Chapel stocks is Grade 50 which is produced up to 4” thick. Anything over 4” is made to a Grade 42, although we often stock it modified to reach the 50 ksi min yield.
