Tensile Strength Of Cold Rolled Steel Sheet

Steel alloy 1020 hot rolled.

Tensile strength of cold rolled steel sheet.

However when cold rolled the tensile strength can increase to 85 000 psi with a yield strength of 70 000 psi. Thus the yield strength of cold rolled steel is higher than that of hot rolled steel. In comparison a cold rolled steel product with the same chemical composition has a yield strength of 365 mpa. Tensile strength elong.

1020 carbon steel is one of the most commonly used plain carbon steels has good machinability and weldability. Steel alloy 1020 normalized 925 c. 3 1 tensile strength elongation and non aging property the steel sheet and coil of standard temper grade and as annealed one shall be tested in accordance with 10 and their tensile strength elongation and non aging properties shall be as given in table 4. 210 30 min 380 55 min 25 min steel alloy 1020 cold drawn.

Tensile properties can vary but are usually between 500 800 n mm2.

Jfe steel has developed continuous annealing equip ment1 3 which is necessary in the manufacture of high strength steel sheets and was among the first to com mercialize and expand the use of ultra high strength. 2 cold rolled steels product description. Press hardenable steels phs press hardenable steel phs commonly referred to as mn22b5 or 15b22 is available as cold rolled full hard or annealed and tempered. It is normally supplied in cold drawn or as rolled.

Mpa ksi mpa ksi steel alloy a36 hot rolled. En8 is an unalloyed medium carbon steel with good tensile strength. This material is used in hot stamping applications to achieve final ultimate tensile strength approaching 1500 mpa. Identical steels classified by the american iron and steel institute as aisi 1018 when hot rolled will have a tensile strength of 67 000 psi and a yield strength of 45 000 psi.

As an example a hot rolled steel product may have a yield strength of 235 mpa. What it s used for cold rolled steel is much more preferred in the machining world where the quality of the steel is an important factor of the quality of the final product and the appearance of the steel is also an important factor. Aisi 1020 steel is also known as c1020 steel in cold worked cold rolled and cold drawn condition. Sae aisi 1020 mild steel can be hot rolled or cold drawn but it is usually in turned and polished or cold drawn conditions.

The rolls induce plastic deformation.
