ASTM A366 ASTM A1008 Steel

AISI 1008 is a Standard grade Carbon Steel. It is composed of (in weight percentage) 0.10%(max) Carbon (C), 0.30-0.50% Manganese (Mn), 0.04%(max) Phosphorus (P), 0.05%(max) Sulfur (S), and the base metal Iron (Fe). Other designations of AISI 1008 carbon steel include UNS G10080 and AISI 1008.

This alloy is generally used for "commercial quality" cold rolled steel sheet. It is known for its very good formability and comparatively high strength. It has a very good surface finish that is far superior to hot rolled A36. 1008 Steel is an economical, general purpose steel grade offering moderate strength and toughness. As a standard grade, 1008 steel is used in many common, low-stress applications.

The term steel refers to iron in which 0.02 to 1.7% carbon has been added. There are many different types of steel and various alloys and applications for each type. Generally steel is low cost and it is easy to finish with paint or other coatings. This makes steel a popular choice for many different types of products. It is used commonly in the manufacturing of automobiles, homes, cutlery, appliances and magnetic cores just to name a few. Steel does however, have poor corrosion resistance.

ASTM A1008 covers cold-rolled, carbon steel sheets, in coils and cut lengths, in the following designations: commercial steel (CS Types A, B, and C); drawing steel (DS Types A and B); deep drawing steel (DDS); extra deep drawing steel (EDDS); structural steel (SS Grades 25[170], 30[205], 33[230] Types 1 and 2, 40[275] Types 1 and 2, 50[340], 60[410], 70[480], and 80[550]); high-strength low-alloy steel (HSLAS Classes 1 and 2 of Grades 45[310], 50[340]. 55[380], 60[410], 65[450], and 70[480]), high-strength low-alloy steel with improved formability (HSLAS-F Grades 50[340], 60[410], 70[480], and 80[550]); solution hardened steel (SHS); and bake hardenable steel (BHS).

Conformance of the steel sheets to chemical composition requirements shall be tested by heat analysis. Specimens shall also undergo tension and bending tests and shall conform to specified values of tensile and yield strength, elongation, and bake hardening index. Unless otherwise indicated, sheet surfaces shall have a matte finish and shall be oiled.
