Industrial Castings | Carbon Steel, Stainless Steel, Alloy Steel
Our foundry in South Korea was founded in 1989, specializing in producing various wear-, heat-, corrosion-, and abrasion-resistant castings. Typical castings include a range of carbon and carbon-manganese steels (SCHP2, WCB), austentic stainless steels (SCS14A, CF8M), and various alloy steels (SCHP32/CF, WC9).
Our refining and alloying practice includes Carbon, Metal Nickel, Ferro Chrome, Ferro Molybdenum, Ferro Silicon, Ferro Manganese, Copper, Nitrogen-Chrome, Columbium, Titanium, Tungsten, Aluminum, Vanadium, and Calcium-Silicon. We may also be able to accommodate special requests for other materials.
We utilize high speed induction furnaces and have 3 ton ladles to producing steel casting weights ranging from 1 kg to 2,500 kg. The majority of our processes are conducted in-house including nondestructive x-ray and gamma-ray (Co-60 & Ir-192) radiography testing.

Power Generation & Industrial Plant Steel Castings
We have over 25 years of experience casting carbon steel and stainless steel valves and valve components for the power generation and industrial plants include globe valves, check valves, ball valves, butterfly valves (BFV), plug, rotary, safety, strainer, and gate valves. We also produce complex shaped steel castings for volute covers, pump casings, and impellers.
Our expertise in shell mold casting of various heat resistant and wear resistant steels allows us to maintain tight casting tolerances. Due to the ability to maintain close tolerances for products such as biomass incinerator grate bars, many of our clients have often found that minimal or no further post-casting machining process is required thus resulting in time and cost savings.

Steel Mill Casting Project Case: High quantity, strict quality steel castings under tight deadline
The biggest challenge for this steel casting project was the tight deadline that our client needed the castings by. Our US client was looking for a casting shop that was able to accommodate their aggressive deadline that most other shops were not able to accommodate. We had to tightly manage the project; we calculated the exact time that each process takes from wooden pattern design to manufacturing and casting production; then we ensured the process to make zero defects. We first shared our manufacturing schedule that outlined the number of end bells we were scheduled to finish each day from molding process, melting process, casting completion, LP inspection to shipment. We also reported our manufacturing process on a regular basis.

| Shipment | Arrival at Port |
This client specifically required to carry out LP inspection to 100% of the castings under the requirement condition SPR-LPR/APR to NF EN 1371-1. Weld areas were to be cleaned up to SP3/CP3 standards, and LP3/AP3 to EN1371-1 (100% testing) when machined. Mechanical testing, chemical composition, and LP inspection were performed on 100% of the castings, and reports were sent for client’s review upon shipping. Material certificate was also to be reported for all steel castings with the heat treatment number written in visible location for each casting.
