Smaller team but have big dream for centrifugal castings

-LAWAI INDUSTRIAL CORPORATION

LAWAI is the boutique-sized centrifugal casting foundry with over 30 years’ experience in Taiwan. The scale is not large but complete, the alloys we are able to manufacture are enough for most industries including oil & gas, green energy, aerospace, petrochemical, marine, food, IT tech, valve, automobile and mechanical…etc. 

Although LAWAI is the Taiwan centrifugal casting supplier, most our centrifugally cast tubes and rings were supplied to U.S.A..  In the past decade, a large part of our centrifugal castings were applied in oil extraction and drilling.  The materials of those centrifugally cast rough machined sleeves, tubes and plates are modified A747 17-4PH,  A436 Ni-resist type 1 and common stainless steel. Because of the prosperous oil industry, our 17-4PH and Ni-resist type 1 centrifugal castings became the dominant and very successful materials at LAWAI.  

Main materials of centrifugal casting at LAWAI

Not only applied in oil gas industry, 17-4PH centrifugal castings are great material used in aerospace, green energy, food, valve and other industries because of its good corrosion resistance and excellent strength and hardness. Based on different applications, the 17-4PH centrifugal castings would be able to be heat-treated to reach to the ideal conditions for the usages. Therefore, several engineers selected 17-4PH centrifugal casting as a key component material. 

A436 Ni-resist type 1 centrifugal casings are also not limited to being as the pump liners in oil & gas industry.  The Ni-resist type 1 is the alloyed cast iron with the sufficient nickel content that is much superior than common cast iron at the aspects of corrosion resistance in salty and mild acid environment and oxidation resistance and wear resistance.  Therefore, Ni-resist type 1 centrifugal castings are suitable for being the material of the critical components in the sea water environment.   Additionally, Ni-resist type 1 connects with the aluminum pistons well.  Therefore, Ni-resist type 1 centrifugal casting is still an important material of ring carrier (Alfin ring) for pistons of diesel engines nowadays.  However, there are several variations of the chemical compositions of ring carriers. They might not the A436 type 1 but they are also the Ni-resist just similar to type 1. 

If customers have the requirements of country of origin of Alfin rings, LAWAI’s alfin rings made in Taiwan are always the priority on customers’ mind. 

Comprehensive alloys in stainless steel and heat-resistant steel for centrifugal castings

In addition to 17-4PH and Ni-resist 1, ASTM A297 heat-resistant alloy centrifugally cast tubes including HP, HF, HK, HH, HU…etc are other important materials at LAWAI. The alloy design of heat-resistant alloys on ASTM A297 are for casting technique.  Until today,  centrifugal casting is still the irreplaceable method to produce cylindrical and symmetrical tubes of these heat-resistant steel.  And LAWAI’s heat-resistant centrifugally cast tubes and rollers were applied in petrochemical, green energy, steel, automobile and thermal process industries abroad mainly. 

ASTM A351 heat-resistant alloys for pressure vessels such as HK40, CT15C( superalloy INCOLOY 800H) are also the superior centrifugal casting materials LAWAI produces.  

Now LAWAI’s INCOLOY 800H centrifugally cast tubes are produced for local petrochemical companies mainly. 

If potential customers would like to purchase the heat-resistant alloy tubes made in Taiwan, LAWAI’s centrifugally cast tubes will be the idealist choice. 

When it comes to stainless steel centrifugal castings, 304, 304L, 316, 316L, 330,  CF3M-HM, duplex 2205 and duplex 2507 are produced frequently at LAWAI, too. 

The common stainless steel such as 304, 316 is the basic alloys, however LAWAI’s centrifugal castings are unique and irreplaceable because we not only cast the liquid metals into the mold but also LAWAI team’s passion, dreams and conscientiousness. We always tell customers that “ LAWAI’s centrifugal castings could be used for hundred years because each piece is made by us-wholehearted production.”

Staying the course, being true and supplying the best centrifugal castings 

Each word and picture on LAWAI’s website you see is the foundry life and experience at LAWAI.  We would like to let international customers understand who we are and what we could supply for you.  

If you could not find the alloys on our web or you have the questions regarindg our capacity, please email to tell us your demands of centrifugal castings.

LAWAI team are looking forward to working with you soon!
