scope:INTRODUCTION. The intent of this Guide Specification for Highway Bridge Fabrication With HPS 70W Steel, 2nd Edition, hereafter referred to as the HPS Fab Guide is to provide owners, designers and fabricators with the latest recommended methodology to fabricate and weld structures using ASTM A709 or AASHTO M270, Grade HPS 70W (HPS 485W) steel, referred to hereinafter as HPS 70W. AASHTO M 270M/M 270 - Standard Specification for Grades 345W [50W], 345CR [50CR], HPS 345W [HPS 50W], HPS 485W [HPS 70W], and HPS 690W [HPS 100W] have enhanced atmospheric corrosion resistance (Section 13.1.2). Product availability is shown in Table 2.

ASTM A709 Grade HPS 70W Steel Plates ASTM Weathering Steel Specifications Central Steel ServiceASTM A242. ASTM A242 is a high strength low-alloy structural steel specification with improved atmospheric corrosion resistance. This specification is normally applicable to steel plates through one-half inch in thickness. The atmospheric corrosion resistance of A242 is substantially better than that of carbon steels such as A36 and A572-50 with or without copper addition.
Carbon plate is available in as rolled or heat treated condition, in master dimensions or cut to size for desired part profile. A wide range of carbon plate to certifications or specifications such as ASTM, ASME, API, CSA, AISI, ABS, Lloyds and DNV is also available, as are a comprehensive range of processing services for carbon Carbon Steel Tampa Bay SteelA group of commodity steel shapes that consist of rounds, squares, flats, strips, angles and channels, which fabricators, steel service centers and manufacturers cut, bend and shape into products. Merchant products require more specialized processing than reinforcing bar. Low Carbon -1018. A low carbon steel with a medium manganese content.
A709 (Grade 36). ASTM A709 (Grade 50), ASTM A709 (Grade 50W or HPS 70W), and ASTM A992 may be used when required by design. Currently, hybrid girder construction shall be avoided due to small differences in material costs, except when using high performance steel. To ensure proper fabrication of structural steel Filler Metals - Lincoln Electricand HPS 70W and A852 are:MIL 800-HPNi/ LA-75, 860/LA-75 and 960/LA-75. (32) 780 flux is recommended for roundabout applications because of its faster freezing slag. (33) 781 flux is recommended for making high speed, single pass welds on clean plate and sheet steel.

To maximize economy, HPS70W plates were used only for the bottom flanges, where tensile strength is the limit state for design, resulting in a hybrid girder design with HPS70W and A588W steel. Because of the length of the bridge, each girder was field spliced with three segments using HPS70W connection plates and high-strength A325M bolts.
ASTM 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.
