    CALL CHATHAM STEEL FORHIGH STRENGTH & ALLOY STEELS

    HIGH STRENGTH LOW ALLOY (WEATHERING) STEELSA242, A588, A606 TYPE IV

    A family of premier, atmospheric corrosion resistant (weathering)high strength low alloy structural steel shapes, plates and bars forwelded, riveted or bolted construction but intended primarily for

  • CHATHAM STEEL CORPORATION 31

    use in welded bridges and buildings, where savings in weight oradded durability are important. The atmospheric corrosion resistanceof this steel in most environments is substantially better than that ofmost carbon structural steels with or without copper addition. In fact,the corrosion resistance is aproximately four times that of A36.

    ASTM A572-50

    High-Strength Low-Alloy Columbium Vanadium Structural Steel

    This specification covers four grades of high-strength low alloystructural steel shapes, plates, sheet piling and bars. Grades 42 and50 are intended for riveted, bolted, or welded construction of bridges,buildings and other structures. Grades 60 and 65 are intended forriveted or bolted construction of bridges, or for riveted, bolted orwelded construction in other applications.

    For welded bridge construction notch toughness is an importantrequirement. The use of columbium, vanadium, and nitrogen orcombinations thereof, within certain limitations shall be at theoption of the producer.

    ASTM A709

    The standard specification for carbon and high-strength low-alloystructural steel shapes, plates, and bars and quenched and temperedalloy steel for structural plates intended for use in bridges. It isavailable in six grades and four yield strength levels.

    A709-36 A709-50W A709-100A709-50 A709-70W A709-100W

    Grades 50W, 70W and 100W have enhanced atmospheric corrosionresistance.

    The ASTM A709 specification meets all the requirements of theAmerican Association of State Highway and Transportation Officials(AASHTO) codes.

    ASTM A656

    Hot-Rolled Structural Steel, High-Strength Low-Alloy Plate withImproved Formability

    This specification covers high-strength, low-alloy, hot rolled structuralsteel plate for use in truck frames, brackets, crane booms, rail cars,and similar applications. Steels that conform to this specificationoffer improved formability. These steels shall be made to a killedsteel fine grain practice, and include specified alloying elements.These steels are normally furnished as rolled. The product isfurnished in two types and four strength grades.

    PRESSURE VESSEL QUALITY (PVQ) PLATE

    ASTM A516

    This specification covers carbon steel plates intended primarily forservice in welded pressure vessels where improved notch toughnessis important. Plates under this specification are available in fourgrades.

    Grade 55 Grade 65Grade 60 Grade 70

    Plates 1.50" and under in thickness are normally supplied in theas-rolled condition. The plates may be ordered normalized orstress relieved or both. Plates over 1.50" thick are required to benormalized. A516 grade 70 is the grade that is stocked by mostwarehouses.

    Other pressure vessel quality (PVQ) plates not as popular as A516are ASTM A285, ASTM A515 and ASTM A387. ASTM A285 andASTM A515 have basically been replaced by ASTM A516. ASTM387 is an alloy (PVQ) plate.

    ASTM A514

    This ASTM specification covers quenched and tempered alloy steelplates of structural quality in thickness of 6" and under, intendedprimarily for use in welded bridges and other structures. When thesteel is to be welded, it is presupposed that a welding proceduresuitable for the grade of steel and intended use or service will beuti
