NSBA White Paper - AISCASTM A709, Grade HPS-70W, has sparked renewed interest in weathering steel within the bridge marketplace. The new HPS material has weathering characteristics that are an incremental improvement over the Grade 50W material used to date. In general, weathering steels contain small amounts of
ASTM A709, and can be acquired in grades 50W, HPS70W, and HPS100W where these numbers correspond to each grades yield strength in ksi. A new generation of high-performance steel (those grades prefixed with HPS) provides weathering performance with a slightly greater resistance to atmospheric corrosion than its predecessors.File Size: 171KBPage Count: 3Weathering Steel Specifications & Benefits | Central Steel a709grade hps70w bangladesh spray paintInitial cost benefits: Cost savings from the elimination of any protective paint system may outweigh the additional material costs. For example, the cost of weathering steel has been shown to be approximately 5 percent lower than conventional painted steel alternatives in bridges using a HA Type 2 paint system.Structural Steel Analysis And Design: Fundamentalsin use for bridge construction is HPS70W. HPS70W is a derivative of ASTM A709 Grade 70W steel. Compared to ASTM A709 Grade 70W, HPS70W has improved mechanical properties and is more resistant to post-weld cracking even without preheating before welding. The stress-strain curves for several types of steel are shown in Figure 1.
A709 Grade 50W and Grade 70 HPS - 70W. This steel eliminates the need for painting because the steel weathers to form a protective patina, or thin layer of protective oxide coating, that prevents the steel from further rusting. Its slightly higher cost per pound than nonweatheringSTRUCTURE magazine | 26,000 Gallons of CoatingsThe bridges architecture has distinctive delta-shaped girders, made of A709 Grade HPS 70W steel, that complement the Cuyahoga Valley topography without dominating it. The design teams that competed for the work were evaluated on their ability to deliver not just on cost and an ambitious schedule, but also on preserving the aesthetics that define this part of Clevelands landscape.SI2007 - New JerseyAug 24, 2016 · 8.
