Is tinplate SPTE cast iron or steel ?

Do you often see the words tinplate? Do you know whether it is steel or iron? Please follow me below, let me unveil the tinplate for you.

Tinplate is neither cast iron nor steel.

Tinplate is actually a thin steel plate with a specially treated surface.

This type of steel plate is usually low carbon steel, which is tinned on the surface and then treated with a series of cold rolling, annealing and coating processes to give it a surface that is resistant to corrosion, oxidation and abrasion, as well as having good workability and durability.

Production method

There are two production methods, hot plating and electroplating.

1. The thickness of the tin layer of the hot plating method is thicker and uneven, the thickness of the coating is also difficult to control, the consumption of tin is larger, the efficiency is low, and its application is limited, so it is gradually eliminated by the electroplating method.

2. Electroplating method is the use of electroplating process in the steel plate substrate uniformly plated with tin film, high productivity, low cost, thin and uniform coating, can produce different thickness of the coating, but also can be single-sided or double-sided plating. Plating method mainly has alkaline plating method, sulfate plating method, halogen plating method and borofluoric acid plating method.

Specificities

(1) Environmental protection: tinplate cans are easy to oxidise and decompose, and are good for waste classification and recycling.
(2) Safety: good sealing, long product shelf life.
(3) Consumption: tin cans have good thermal conductivity, easy to heat but, in line with consumer needs. With sufficient strength and hardness, not easy to deform, more convenient for handling and storage. Product colour multi-level, exquisite appearance, to meet the consumer's visual enjoyment.
(4) Economy: Suitable for large-volume continuous production, low investment costs, so that consumers can enjoy the good quality and inexpensive products.

Application

1. Manufacture of steel: Tinplate is one of the main raw materials for the manufacture of steel. It increases the hardness and strength of steel and makes it more resistant to corrosion.

2. Manufacture of magnets: Because tinplate has good magnetic properties, it is an important raw material for the manufacture of magnets.

3. Manufacture of mechanical parts: Due to its high hardness, strength and resistance to wear, tinplate is usually used to manufacture mechanical parts and tools.

4. Manufacture of musical instruments: the resonance properties of tinplate make it an important material for the manufacture of musical instruments, such as trumpets, horns and piano strings.

5. Manufacture of matches: Tinplate can be used to make the heads of matches, and it is ideal for match making because it can spontaneously combust in air.

6. Manufacture of chemical reactors: Since tinplate has good corrosion resistance and thermal stability, it is widely used in the manufacture of chemical reactors and catalysts.

In summary, tinplate is not a pure iron product, but a thin steel sheet that has been specially treated.

Tinplate can be found everywhere in daily life. I hope this film article is helpful to you.
