HOT ROLLED SHEET & COIL

LOW CARBON,COMMERCIAL QUALITY –  A low coststeel sheet, soft enough to bend flat on itself in any direction withoutcracking, ductile enough for shallow drawing. Carbon is .10 max. for improvedwelding and forming. Surface has normal mill oxide. Conforms to ASTM A-569.Used for tanks, barrels, farm implements and other applications where surfacefinish is not critical.

PICKLED AND OILED–  Acid pickling removes mill oxide,improving surface appearance, uniformity and finishing quality. Paint andenamel adhere well after cleaning. Same properties and forming characteristicsas commercial quality but less wear on tooling. Conforms to ASTM A-569. Typicalapplications: auto and truck parts, farm implements, tanks, stamped and rollformed pats, formed sections.

DRAWING QUALITY –Used in fabricating parts where drawing or severe forming may be involved andsurface appearance is not of primary importance. Conforms to ASTM A-621.Typical applications: auto and truck parts, stamped parts and roll formed

.40/.50 CARBON –High carbon content increases yield strength about 50% over low carbon.Abrasion resistance is also improved compared with low carbon. Heat treatablefor still greater strength and hardness. Far less formable and weldable thanlow carbon. Used for scrapers, blades, tools and other applications requiring astrong, moderate cost sheet.  Identificationcolor: yellow.

ABRASION RESISTING-Medium carbon content plus higher manganese greatly improves resistance toabrasion. Typically used for scrapers, liners, chutes and conveyors. Outlastslow carbon steel by two to ten times. Moderate formability. Identificationcolor: pink.

HIGH STRENGTH/LOW ALLOY SHEETS

Have much higher minimum yield strengths, improvedformability, weldability and/or atmospheric corrosion resistance than ordinarylow carbon commercial quality sheets. Lend themselves to applications whereweight reduction is a main factor. Extra strength permits weight savings up to25%. Produced to minimum mechanical requirements. Available in three types:

CONVENTIONAL TYPEASTM A-607 – Lowest cost HSLA steels made to specific minimum yield strengthswhere atmospheric corrosion resistance is not a requirement. Good formabilityand weldability. Typical applications: transmission towers, formed utilitypoles, auto parts, truck trailers. Identification color: white, green, white(INX 45), white and green (INX 50, Ex-Ten 50).

IMPROVED ATMOSPHERICCORROSION RESISTANCE TYPE – ASTM A-606

Two to four times more resistant to atmospheric corrosionthan low carbon steel. Unpainted, Cor-Ten has tightly adherent oxide surfacewhich stops further oxidation. Excellent weldability and formability.Identification color: white (Cor-Ten).

IMPROVED FORMABILITYTYPE ASTM A-715 (HI-FORM) – Maximum formability with improved toughness andfatigue resistance. Good weldbility. Available with minimum yield ranging from50,000 psi to 80,000 psi. Used when fabrication involves difficult forming ortight radii bending.
