When the production is completed, we have QC to conduct functional testing and carry out comprehensive quality inspections to ensure the quality of the product. This commitment to quality assurance ensures that our products meet the highest standards and exceed the expectations of our customers.

一、Origin of Stainless steel

Stainless steel is a type of steel, which refers to steel containing less than 2% carbon (C), and iron containing more than 2%. During the smelting process, the addition of alloying elements such as chromium (Cr), nickel (Ni), manganese (Mn), silicon (Si), titanium (Ti), molybdenum (Mo), etc. improves the performance of steel and gives it corrosion resistance (i.e. no rusting), forming what we commonly refer to as "stainless steel".

二、Classification of stainless steel

According to the classification of organizational status, it can be divided into the following five categories:

1.Austenitic stainless steel

         Contain more than 18% chromium, as well as about 8% nickel and small amounts of elements such as molybdenum, titanium, and nitrogen.

         Advantages: Good comprehensive performance (high temperature strength, oxidation resistance, welding performance, etc.), resistant to corrosion from multiple media.

         Disadvantage: It is particularly sensitive to media containing chloride ions (CL).

         Like: SS304,SS201,SS202 etc.

   Win Tend always use SS201 to produce kinds of trolleys、work tables、GN Pans、sinks and cabinets etc. SS304 also is accept, if customer agree to use more expensive SS304, we also also do, like our South African customers always require 304 material to cope with the hot and humid environment in the local area.

2.Martensitic stainless steel

Chromium mass fraction is 11.5%~18.0%, carbon mass fraction can reach up to 0.6%.

         Advantages: It is usually used as a material for making parts and tools with high stress, and is used for making stainless steel utensils such as knives and scissors.

         Disadvantages: Poor plasticity and weldability.

         Like: SS410, SS420 etc.

3. Ferritic stainless steel

Containing 12% to 30% chromium.

        Advantages: Corrosion resistance, toughness, and weldability improve with increasing chromium content, and chloride stress corrosion resistance is superior to other types of stainless steel.

        Disadvantages: Steel has high sensitivity to notches and brittle transition temperature, and is also more sensitive to intergranular corrosion after heating.

        Like SS409,SS430,SS443 etc.

        Win Tend usually use SS443 material as the bottom or the body of stock pot.

4. Ferritic austenitic stainless steel

It has the advantages of both austenite and ferrite stainless steel, and has superplasticity.Like 329J3L,329J4L, they are not used in the catering and kitchenware industry.

5. Precipitation hardening stainless steel

  It is mainly used to manufacture containers and structural parts that require high strength and corrosion resistance, and can also be used as high-temperature parts, such as steam turbine parts.

三、The main characteristics of stainless steel

1. Weldability

2. Corrosion resistance

3. Polishing performance

4. Heat resistance performance

As stainless steel has these excellent characteristics, we have chosen to use stainless steel to manufacture various kitchen utensils and supplies.

In the market, due to the similar colors of stainless steel and aluminum products, there is often confusion. Win Tend provides two suggestions to help you distinguish between them:

一、 Appearance inspection method

Aluminum and stainless steel have certain differences in appearance, so compare them carefully when placed together. Aluminum is usually silver white or light gray, while stainless steel is usually dark gray or silver. In addition, in terms of appearance, aluminum usually oxidizes to form a protective film, while stainless steel does not.

二、 Weight testing method

The density of aluminum and stainless steel is different, so using weight for identification is also a more reliable method. The density of aluminum is about 2.7 grams per cubic centimeter, while the density of stainless steel is about 7.9 grams per cubic centimeter. So, if you compare aluminum and stainless steel blocks of the same size, you will find that stainless steel is much heavier than aluminum.

Based on different factors, many customers may have the following questions:

(1) Which one should I use, stainless steel or aluminum?

The choice depends on your application requirements. The use of aluminum can achieve lightweight, high thermal conductivity, and easy processing characteristics. On the other hand, stainless steel is an ideal choice for high strength, excellent corrosion resistance, and durability.

(2) Which is stronger, aluminum or stainless steel?

Stainless steel is stronger than aluminum and suitable for high stress applications.

(3) Is stainless steel more corrosion-resistant than aluminum?

Yes, stainless steel is more corrosion-resistant than aluminum because it contains chromium, which can form a protective oxide layer.

(4) What are the advantages of aluminum compared to stainless steel?

Aluminum is lighter, easier to process, has higher thermal and electrical conductivity, and is cheaper in price.

(5) When should we choose stainless steel instead of aluminum?

When you need high strength, excellent corrosion resistance, and durability in harsh environments (such as medical, marine, food processing, and building components), choose stainless steel.

The thinnest thickness of stainless steel is usually 0.02mm. This thin stainless steel is also known as "silver foil", which has the characteristics of strong flexibility, good corrosion resistance, and good conductivity. Therefore, it is widely used in fields such as microelectronic devices and solar cells.

There is also a product called stainless steel spring plate, which can be as thin as 0.08mm. Stainless steel spring plate has excellent yield strength and tensile strength, which allows it to withstand large loads and high stresses, as well as good plasticity and deformation ability. It can be cold processed and formed to adapt to various complex shape requirements.

In our stainless steel kitchenware industry, for products like serving trolley, the thinnest of the board can be made 0.5mm thick, and for pots, the thinnest could be made 0.6mm. Of course, according to different customer requirements, we also could customize different thicknesses for them.
