The main differences between 303 and 304 stainless steel lie in their chemical composition, properties and applications:
Chemical composition
The content of sulfur (S≥0.15%), phosphorus (P≤0.20%), and carbon (C≤0.15%) in 303 stainless steel is higher than that in 304. The nickel (Ni 8-10%) and chromium (Cr 17-19%) content in 304 is even higher.
Performance difference
Corrosion resistance : 304 is superior to 303 and is suitable for fields such as chemical engineering and medical care;
Cutting performance : 303 Due to the presence of sulfur and phosphorus elements, it has better cutting performance and is suitable for automatic lathe processing.
Wear resistance : In some scenarios, the wear resistance of 303 May be better than that of 304.
Typical uses
303: Fields that require high cutting efficiency, such as metal stamping parts, bolts, and bushings;
304: Scenarios that require comprehensive performance, such as electrical panels and chemical equipment
All of our stainless steel CNC machined threaded fittings are made according to customer's drawings or samples. They could be standard size or non-standard size. The below chart is to show how we serve to our customers:
Superior Material Performance:
303 Stainless Steel: Offers excellent corrosion resistance (crucial for marine, chemical, food processing), good mechanical strength, and exceptional machinability. This translates to longer lifespan, reduced maintenance, and lower risk of failure in harsh environments compared to alternatives like carbon steel or plastic.
SS Clip Assembly: Ensures a robust, vibration-resistant, and secure connection critical for safety and reliability in dynamic applications.
Precision & Consistency Guaranteed by CNC Machining:
Delivers exact dimensional accuracy and repeatability, essential for complex assemblies, tight tolerances, and interchangeability. Eliminates fitment issues common with lower-precision methods.
"Custom" is a Major Value Driver:
Solves specific problems: Buyers aren't forced to adapt their design to an off-the-shelf part that might be suboptimal.
Optimizes Performance/Integration: Perfectly fits unique applications, existing machinery, or bespoke systems.
Competitive Edge: Enables innovative designs or improvements competitors using standard parts can't achieve.
Streamlined Assembly & Maintenance:
The integrated SS clip assembly facilitates quick attachment and detachment. This speeds up initial installation, simplifies field maintenance, and reduces labor costs – a significant advantage for serviceability.
Single-Source Solution: Combines the fitting and the secure fastening mechanism (clip) in one reliable, custom-machined component, simplifying sourcing and BOM management.

FAQ:
1Q: Why choose 303 stainless steel for this fitting?
1A: 303 SS offers excellent corrosion resistance, good strength, and superior machinability ("free-machining") for precise, complex custom parts, ensuring durability and cost-effective production.
2Q: What level of customization do you offer?
2A: We fully customize dimensions, thread types, port configurations, and clip design to meet your exact application requirements and integration needs. Provide your specifications or drawings.
3Q: How do you ensure quality and precision?
3A: All fittings are CNC machined to tight tolerances (typically ±0.05mm or better) with rigorous in-process and final QC checks, including dimensional verification and material certification.
4Q: What are the advantages of the integrated SS clip assembly?
4A: The clip provides a secure, vibration-resistant, tool-less connection, enabling quick installation/removal, reducing assembly time, and enhancing reliability in dynamic environments.
5Q: What is the typical lead time for custom orders?
5A: Lead time depends on complexity and volume. Standard custom prototypes take 2-4 weeks; production batches typically 4-8 weeks. Expedited options are available.
