Hot Rolled Mild Steel Sheet

Magnetic brinell 95 tensile 52 000 yield 38 000.

Hot rolled mild steel sheet. Hot rolled comercial quality sheets are produced from mild steel grades like aisi 1008 1010 and exhibit a light scale. Description hot rolled mild steel tread floor plate 0 125 has a 4 way raised lug pattern or diamond pattern on one side providing skid resistance and all around traction with an easy to clean surface. Popular uses for hr steel sheet include. Hot rolled steel sheet plate advantages hot rolling utilizes large ingots and large reduction rolling which not only improves production efficiency but also creates conditions for increasing rolling speed and achieving a continuous and automated rolling process.

The rolls induce plastic deformation. Oil is then applied to prevent rusting. Hot rolled steel hot rolling is a mill process which involves rolling the steel at a high temperature typically at a temperature over 1700 f which is above the steel s recrystallization temperature. Hot rolled steel sheet and plate is available as standard hot rolled or as hot rolled p o.

The material can be used for simple bending and forming. Common applications of mild steel. Steel alloy a36 hot rolled.

Automotive panels tool boxes hoppers drip pans fuel tanks trailer siding roofing etc. In comparison a cold rolled steel product with the same chemical composition has a yield strength of 365 mpa. 350 51 min 420 61 min 15 min steel alloy 1020 annealed 870 c 295 42 8 395 57 3 36 5. This slab of mild steel is then usually brought down to the desired size using processes called hot rolling or cold drawing although there are other methods that can also be used.

210 30 min 380 55 min 25 min steel alloy 1020 cold drawn. Hot rolled pickled and oiled mild steel sheet hot rolled pickled and oiled abbreviated as p o or hrpo is a further treatment to hot rolled sheets. Steel alloy 1020 hot rolled. Hr steel sheets are easy to weld form and drill and has a slight grainy surface.

Thus the yield strength of cold rolled steel is higher than that of hot rolled steel. The sheet is dipped in an acid based solution to remove impurities such as scale inorganic contaminants stains etc from the surface. As an example a hot rolled steel product may have a yield strength of 235 mpa. Steel alloy 1020 normalized 925 c 345 50 3 440 64 38 5.
