What is the difference between cold rolled steel and hot rolled steel?
1.What is cold rolled steel?
The steel plate is further rolled to the target thickness at room temperature, called cold-rolled steel
Features of cold-rolled steel: smooth and beautiful surface, with superior mechanical properties, especially processing properties.
The disadvantage is that the production process is complex, the production efficiency is low, and the equipment requirements are relatively high to meet the production needs. At the same time, in order to eliminate work hardening during production, it must be quenched continuously.
2.What is hot rolled steel?
Hot-rolled steel is steel produced through continuous high-temperature treatment of hot-rolled billets.
The characteristics of hot-rolled steel: high willfulness and strong compressive ability. The steel has high plasticity, and the corrosion resistance can be greatly enhanced by adding special elements.
The disadvantage is that the surface is not as smooth as cold-rolled steel, appears dark black, and the hardness is not as high as cold-rolled steel.
So is the stainless steel water cup suitable for hot-rolled steel or cold-rolled steel?
The stainless steel water cup uses hot-rolled steel with special elements, which not only has high toughness, but also has high stability and high corrosion resistance. However, some unscrupulous manufacturers in the market currently choose to use cold-rolled steel to pretend to be hot-rolled steel in order to reduce the cost of water cup processing. The surface effect of cold-rolled steel is good and can be used as 304 stainless steel, and ordinary consumers cannot distinguish it without special equipment or potion.
