Our stainless steel hollow bars are able to replace forged bars

If you are searching for the stainless steel hollow bars, which manufacturing method will be your priority?

Centrifugal casting or forging?

Most our customers would look for the stainless steel hollow bars manufactured by forging first.  However, they confronted the problems that the costs of the forged bars were high or the material selections of forged bars were limited. 

The costs of our stainless steel hollow bars produced by centrifugal casting technique could be lower and various materials are able to be cast.  Therefore, puchasing stainless steel hollow bars manufactured by centrifugal casting might be a good idea. 

Let me explain more why centrifugally cast stainless steel hollow bars are able to replace forged bars. 

The manufacturing method of the stainless steel hollow bars

LAWAI’s stainless steel hollow bars are 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 structures are dense and without the cavities.

How to distinguish the stainless steel hollow bars from the tubes?

The appearance of stainless steel hollow bars are like tubes very much.  However, the quality, strength and prices between stainless steel hollow bars and tubes will be much different due to different manufacturing methods.

At LAWAI, we call our centrifugally cast tubes as seamless stainless steel tubes.  But, it could cause misunderstanding if we only call them tubes not seamless tubse.  Because most people regard tubes as the ones are produced by coils and welding construction.

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

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

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

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

The materials of stainless steel hollow bars we supply

There is a wide material selection for stainless steel hollow bars manufactured by centrifugal casting technique.  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 requests no matter the project is small or large.  The centrifugal casting method is good to do the customized projects!
