Product Description:

1.Structure of Tin Free Steel TFS for Twist-off Caps and Crown Caps Description


Tin Free Steel (TFS) is thin black plate with two coats; one of metal chrome film and the other of chromium oxide. TFS is ideal for the manufacturing of crowns, container ends & shallow drawn cans etc. TFS is also known as Chromium coated steel.


2.Main Features of the Tin Free Steel TFS for Twist-off Caps and Crown Caps


Also known as chromed steel, tin-free steel (TFS) is obtained by coating the metal base (low-carbon steel) with an ultra-thin layer of metallic chrome and then with a chromium oxide layer.

Q:Does the tinplate have a tensile rate? Thank you heroes!
Yes, what does it look like?. Deep drawing pot should be higher tensile rate (also known as elongation), the harder the material, the lower the tensile rate; the industry generally does not have a uniform tensile rate, generally in order to replace the cup burst value test.
Q:Why tinned fruit cans, some snow wall, and some inner wall does not appear?
Tin cans inside must use the high Xiliang (11.2 - 15.1), the inner wall of the conventional oxidation after a snowflake, which belongs to the benign chemical reaction, enhance the taste.
Q:How to test the tightness of tin metal cans?
The empty tank which has been cleaned can be dried by 35, and the pressure or pressure leak test shall be carried out according to the equipment condition of each unit. B.1 pressure leak test, the empty tank will be carefully injected into the water until eight or nine into full, the rubber ring will be placed in the appropriate plexiglass plate at the opening side of the roll, so that it can be sealed. Start the vacuum pump, turn off the bleeder valve, hold down the cover by hand, control the pumping, and make the vacuum gauge rise from 0Pa to 6.8X10 PA (510mmHg) for more than 1min, and keep the vacuum above 1min.
Q:A tin rust problem for help
The rusty cans, the best prevention is to use empty cans of good quality, ensure the tank, the outer wall of the antirust paint, coating thickness and curing degree basically no problem, pay special attention to the weld coating is complete. Choosing a good supplier and improving the inspection of empty cans are very important.
Q:What's the difference between iron, aluminium, stainless steel, galvanized iron and tin?
Aluminum is a kind of material. It is not easy to be oxidized when it meets water. The price is moderateStainless steel is another kind of material. It is not easy to be oxidized when it meets water. The price is high
Q:You can do is tin iron electromagnet
Tinplate is a tin covered with tin, it is not easy to rust, also known as tin iron.
Q:Cookies with tinplate packaging has what advantage?
Good mechanical properties: tinplate cans relative to other containers, such as plastic, glass, paper containers and strength, and good rigidity, it is not easy to break. It is not only used for small sale packing, but also the main container for large transportation package.
Q:What is the process of two cold rolling of tinplate?
Tin plays a major role in preventing corrosion and rusting. It will be the steel strength and formability and corrosion resistance of tin soldering, and beautiful appearance with a material, corrosion resistant, non-toxic, high strength and good ductility properties.
Q:Can you tell me how to deal with the recycling of tinplate?
The tin is magnetic, is easy to recycle scrap. Second, waste tin as scrap iron and steel melted, make steel containing a small amount of tin (less than 0.1%), to improve the performance of cast iron.
Q:What is the difference between food grade tinplate and ordinary chemical tinplate? What is the difference between MR material and SPCC?
No general food grade and ordinary chemical tinplate tinplate. There are some major is not mature in domestic tin (MR, L, D) the production of tinned steel substrate outside, technology is not mature, not environmental protection, so there is a risk for food cans, can only be used for chemical tank.
