    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.

    QUENCHED AND TEMPERED STEEL

    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 beutilized.

    There are fourteen different grades of A514, each differing in theirchemistry. Although A514 is produced to a maximum thickness of6", not all of the grades are available to that thickness.

    This specification is utilized primarily for its high yield to weight ratio.Plates 2.50" and under have a minimum yield strength of 100,000psi. Plates over 2.50" to 6" have a minimum yield strength of90,000 psi. These yield strengths are approximately three timesthe strength of A-36.

    All steel plates have a particular hardness value. A514, being aquenched and tempered alloy steel has a Brinell hardness rangeof 235-293 through 3/4" thickness per ASTM specifications. ThisBrinell hardness will not appear on any mill certification, sinceA514 is used for strength only.

  • CHATHAM STEEL CORPORATION 33

    ABRASION RESISTANT STEEL PLATE

    Steel plate comes in a wide range of hardness. Hardness in steelcan be defined as resistance to penetration. Abrasion resistantplate is manufactured to a Brinell hardness. Hardness is measuredusing a Brinell test. The smaller the indentation on the plate surfaceafter the Brinell test, means less penetration and the harder theplate surface. Hardness in steel is directly proportional to tensilestrength. As hardness and strength increases, the formability andweldability of steel decreases. Even though there is a directcorrelation between steel hardness and tensile strength, millproducers will not certify to both.

    There are two types of abrasion:

    1. Impact abrasion surface is worn away by chipping, spallingor cutting caused by hard materials striking the surface.

    2. Sliding abrasion surface is worn away by friction, such assand sliding down a chute.

    There are no specific ASTM specifications for abrasion resistant(AR) steel. Over the years, steel producers, end users and wearplate distributions have developed trade names and specificationsfor a general group of applications that have become standard inthe industry.

    Because there are no published standards there can be a greatdeal of flexibility in the chemistries used.

    AR steels are usually tested for surface hardness only.

    The specific AR steels fall into the following ranges.

    TYPE GRADE BRINELL RANGE

    Carbon as rolled AR235 235 Typical (not tested) - has an approximatebrinell hardness of 235

    Alloy (Q+T) 500 Formable 477 min 477-534

    The 400 formable and 500 formable combine the benefits of a lowsulfur, low carbon equivalent chemistry to improve both weldingand cold forming characteristics beyond traditional abrasion resistantsteels. Also, unlike traditional AR steels, the 400 formable steel hasa through-thickness hardness.
