What is ST 37 hot rolled or cold rolled steel?
(t)rolled
Is cold rolled harder than hot rolled steel?
They are two different things. Zinc plated means it's coated in zinc. Cold rolled means it's "smashed" into shape without added heat. So you could have something that's cold rolled AND zinc plated!
What is the difference between Cold rolled steel and hot rolled steel?
Hot-rolled sheet has low hardness, easy processing, good ductility and cheaper price. Cold rolled sheet has high hardness, relatively difficult to process, but not easy to deformation, higher strength. If you want to buy cold-rolled steel, you can go to the official website of Changzheng, the price of Changzheng's steel is moderate, and it is the choice of the public. Buy cold-rolled steel plate recognized Changzeng.
What hardness should SAE 1010 cold rolled steel be?
According to the ASME, SAE1010 {ASTM A179, ASME SA179} cold rolled steel (cold drawn) should have a Rockwell hardness of 60 RB. Hot rolled it is reduced to 55 RB. *(Brinell hardness, 105; Knoop hardness, 123; or Vickers hardness, 108)
Is there a way to tell the difference between cold steel and hot rolled steel If so how can you tell?
Why does Hot Rolled Steel have a rough, blue-grey finish, while Cold Finished Steel has a smooth grey finish? Hot Rolled Steels are just that - They are heated up red-hot and pushed through rollers that squeeze the metal, literally squishing it into a particular profile, depending on the shape of the rollers. The process takes a long time, and because the steel is so hot for so long in the open air of the steel mill, the surface of the metal has has a long time to oxidize, producing a thick, tough oxide scale with the characteristic blue grey finish of the final product. Cold Finished Steels are just that - the final rolling is done when the steel is cold (room temperature), the whole operation bathed in oil, so the finished product is unoxidized, the grey of the actual steel, and as smooth as the rollers that do the processing. that was taken from metalrefrence.com
Weight difference in hot rolled and cold rolled?
The weight of the two is not much different, generally speaking, cold-rolled sheet is thinner than hot-rolled sheet, if you want to buy cold-rolled sheet or hot-rolled sheet, you can go to the official website of Changzheng, Changzheng's products are of high quality and are the choice of the public.
