Stainless Steel Gazing Mirror Ball

Stainless Steel Gazing Mirror Ball/Christmas Hollow Sphere With Different Material Brief

---

Hollow balls with material of #201 #304 #306 are able to get a remarkable weigth saving and keep the properties of the correspondent solid balls (mechanical properties, corrosion resistance, magnetism). The low density value allows balls to float.

In short, type 201 Stainless Steel Hollow Spheres are more cheaper but is not as effective at preventing corrosion. If you are looking for more durability at a lower cost for your project and are not worried about exposure to corrosive elements, 201 Stainless Steel Large Ball is a great option for you. 304 Stainless Steel Ball with its higher nickel content is more common in the industry, but it requires more cost due to the rising cost of nickel which makes this type of stainless steel spheres less susceptible to corrosion. While 201 Stainless Steel Hollow Sphere has the lowest resistance to corrosion, and type 304 Metal Ball is more resistant, type 316 Stainless Steel Gazing Ball has the most.

316 Stainless Steel Hollow Ball is ideal for situations with more saline and chloride exposure. Therefore, Haixu Co., Ltd. recommend to choose metal sphere with 316 stainless steel if you requires one with high resistance to corrosion.

Stainless Steel Medium Hollow Sphere Production Processes

---

There are three ways to make a Stainless Steel Hollow Sphere, which are stamping press, water pressured and spinning.

Stamping Press:

It is to shape steel sheet by deforming it with a mould. Then welded two steel hemispheres together and grinding the welding seams. Finally mirror polishing the hollow steel balls.

Spinning:

One of the production method is Spinning, which is also the thickest steel balls option. Firstly we spinning two steel hemispheres, then welding together, finally grinding the welding seams and mirror polishing it. This is the thickest steel ball choice.

Water Pressure

After calculating the specific data for the welding steel sheet size, our technicians bend it to a precise shape,and then our qualified workers weld a similar spherical cube shape and  forming a perfect spherical steel balls with particular water pressure. Finally we’ll grind off the welding seams and mirror polishing it.There’s no standard die limited under this method, making any size on your demand available.

How to Choose The Metal Balls You Want?

Step 1: Material selection

Generally, there are 3 kinds of material for customers to choose from: ss201, ss304, ss316. (The differences among these three is shown above Large Stainless Steel Hollow Balls With Different Material Brief )

Step 2: Size selection and thickness selection

There are various size and thickness for customers to choose from. The size is the diameter of the stainless steel balls you want, while the thickness is also important for the product. Different thickness will make it different in quality and of course, the price. The stronger the thickness is, the heavier the gazing balls are and of course the better quality it is. And also, good thickness will make the metal hollow balls stronger and safer in shipping.

Step 3: Surface Selection

Different people have different needs. Therefore, Haixu Co., Ltd. offers various surface treatment for our customers. As a stainless steel balls/ hemispheres / sculpture supplier who has been in this industry for over 20 years, the most popular surface treatments are mirror polish and brush finished. If you have any requirements in surface treatment, please feel free to contact us.

Step 4: Color Selection

Apart from stainless steel balls with natural color, Haixu Co., Ltd. also provide our customers with spheres with various color, such as golden, golden rose, rainbow color, black, etc. Besides, the color for metal balls can be customized. If you want to make balls with any color you want, do feel free to let us know. (Click here to connect us directly. )

Step 5: Hole Selection & Nut Selection

For customers who would like to make stainless steel hanging balls for decoration or drilling hole stainless steel spheres, you are able to determine the size of the hole. Also, Haixu Co., Ltd. is able to make metal balls with thread and nut.
