Tensile Strength Of Cold Rolled Steel Sheet

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.

Tensile strength of cold rolled steel sheet. The yield strength and tensile strength of cold rolled will be higher than hot rolled which makes cold rolled less likely to fracture under pressure. Tensile strength elongation and non aging property tensile strength n mm. Aisi 1020 steel is also known as c1020 steel in cold worked cold rolled and cold drawn condition. This material is used in hot stamping applications to achieve final ultimate tensile strength approaching 1500 mpa.

As an example a hot rolled steel product may have a yield strength of 235 mpa. 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. In comparison a cold rolled steel product with the same chemical composition has a yield strength of 365 mpa. En8 is an unalloyed medium carbon steel with good tensile strength.

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. Steel alloy 1020 normalized 925 c. Tensile strength elong.

220 250 32 36 400 500 58 72 5 23. The rolls induce plastic deformation. Sae aisi 1020 mild steel can be hot rolled or cold drawn but it is usually in turned and polished or cold drawn conditions. 780 1470 n mm grade cold rolled ultra high tensile strength steel sheet cold rolled super high tensile strength steel sheet with the level forming formability is at the top level in the industry cold rolled super high tensile strength steel sheet with the level forming formability is at the top level in the industry 1.

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. 350 51 min 420 61 min 15 min steel alloy 1020 annealed 870 c 295 42 8 395 57 3 36 5. For this reason steel sheets with tensile strength ts of 980 mpa and higher are frequently used in the cabin structure. However when cold rolled the tensile strength can increase to 85 000 psi with a yield strength of 70 000 psi.

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. Mpa ksi mpa ksi steel alloy a36 hot rolled. 1020 carbon steel is one of the most commonly used plain carbon steels has good machinability and weldability. 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.

It is normally supplied in cold drawn or as rolled.
