Stainless Steel Fittings for Semiconductor Industry Applications

At G HWA, we take pride in manufacturing stainless steel elbows, tees, reducers, and adapters that meet the highest standards, including ASME BPE and JIS specifications. We offer vacuum heat treatment, mechanical polishing (MP), electropolishing (EP), and CFOS cleaning services to ensure oxidation-free surfaces, high purity, and excellent corrosion resistance. These qualities make our fittings ideal for industries that demand ultra-smooth internal surfaces and superior cleanliness, such as semiconductor manufacturing and vacuum applications.

A Leader in High-Quality Stainless Steel Component OEM Manufacturing

We go beyond being a supplier of high-quality stainless steel fittings – we are your trusted OEM manufacturing partner. We possess extensive experience in customizing and producing a wide range of stainless steel components to your specific needs, including:

Stainless Steel Formed Fittings:

Offering a comprehensive range of Elbows, Tees, and Reducers in various sizes (from ¼”-6”, 15A-150A) to accommodate diverse piping system configurations.

Stainless Steel Machined Components:

Manufacturing various types of connectors and adapters suitable for pipeline transitions and instrument piping applications (from ¼”-6”, 15A-150A).

In addition to adhering to ASTM and ASME standards, our products can also be manufactured in compliance with JIS specifications (such as JIS B2312), catering to diverse regional requirements across global markets.

Advantages

Extensive Manufacturing Expertise:

We bring years of experience in both industrial-grade and high-purity stainless steel manufacturing, delivering products with exceptional precision and durability to meet the stringent demands of semiconductor processes. We are also highly skilled in processing special alloys, including SS316L (compliant with SEMI F20 standards), 1.4435, AL6XN, and Hastelloy® C22, to support a wide range of critical applications. Custom processing using customer-supplied materials is also available, we offering maximum flexibility to meet specific application needs.

Rigorous Quality Assurance Processes:

We ensure that every product undergoes comprehensive inspection by our professional QA team to meet international quality standards. From raw material verification and precision machining to final packaging, we maintain strict quality control throughout every stage of production to deliver consistent and reliable product quality. Full inspection reports are available upon request.

Various Surface Finishing Technology:

We offer various surface finishing solutions tailored to meet the diverse needs of semiconductor industry applications. Our Vacuum Heat Treatment (BA) process ensures a clean, oxide-free surface while enhancing material stability. For customized surface roughness (Ra) levels, we provide Mechanical Polishing (MP) to meet specific customer requirements. Additionally, Electropolishing (EP) is available for superior cleanliness and corrosion resistance, making it ideal for high-purity applications such as semiconductor delivery systems.

Optional CFOS Service for Contamination Removal According to ASTM G93 and CGA 4.1 Standards:

We offer optional CFOS (Cleaned for Oxygen Service) cleaning to effectively remove potential contaminants in accordance with ASTM G93 and CGA 4.1 standards. Our oxygen cleaning process helps minimize ignition risks and ensures higher levels of safety and purity for critical applications.

Product Traceability Management:

We emphasize full transparency and quality control throughout our manufacturing processes. All products feature complete traceability from raw material sourcing, forming, welding, to surface finishing, in full compliance with the semiconductor industry’s stringent traceability standards.
