    Stainless steel hollow bar manufacturer

 

 

Our stainless steel hollow bar – is able to replace forged bar

If you are looking for the stainless steel hollow bar, you will ask forging or casting manufacturer?

Most our customers would look for the stainless steel hollow bar manufactured by forging first.  However, they confronted the shortage of the raw materials and the higher cost of forged bars.

Our stainless steel hollow bar produced by centrifugal casting technique is able to replace the forged bars.

If you would like to know more, let’s read the paragraphs below.

 

The manufacturing method of the stainless steel hollow bar

LAWAI’s stainless steel hollow bar is manufactured by centrifugal casting technique.  What is centrifugal casting?  Let me introduce it briefly. The liquid metal is poured into the round mold and the mold is rotated by very high speed.  The centrifugal force would push the liquid metal into the inner wall of the mold.  After that, the mold is cooled by water.  The cooling is from the outside to the inside mold and it causes the directional solidification.  Because of the directional solidification, the metal structure is dense and without the cavities.

 

How to distinguish the stainless steel hollow bar from the tube?

The appearance of stainless steel hollow bar is like tube very much.  However, the quality, strength and price between stainless steel hollow bar and tube will be much different due to different manufacturing methods.

At LAWAI, we call our centrifugally cast tube as seamless stainless steel tube.  But, it could cause misunderstanding if we only call it tube not seamless tube.  Because most people see tube as the one is produced by coils and welding construction.

In order to make everyone understand what we produce, it is better to call our centrifugally cast tube as stainless steel hollow bar.  When hearing hollow bar, most people would think of seamless one.

 

Stainless steel hollow bar – “Seamless and one-piece construction”

Most customers purchase the solid bar then drilling to hollow one.  It would waste the materials and increase the cost.  If buying the stainless steel hollow bar directly, you are able to save machining cost.

The stainless steel hollow bar manufactured by centrifugal casting is seamless and one-piece constructed.  If you have the higher demands of mechanical properties, our stainless steel hollow bar is your good choice.

 

The materials of stainless steel hollow bar we supply

Because we produce the stainless steel hollow bar by centrifugal casting technique, we could manufacture lots of materials.  We are able to produce common stainless steel such like SS304, SS316, 17-4PH and duplex.  We also could provide higher grade heat-resistant steel like Nickel-based alloys.

We make each stainless steel hollow bar based on customer’s request no matter the project is small or large.  The centrifugal casting method is good to do the customized case.
