Introduction
Searching for stainless fittings that outperform 201 in strength yet undercut 304 in price? 202 stainless steel fittings (UNS S20200) are your answer. This nitrogen-strengthened, manganese-rich austenitic grade delivers 30–40 % higher yield than 201 while slashing material cost by 35–45 % versus 304. From mirror-polished handrail elbows to deep-drawn tee reducers, 202 stainless steel fittings keep high-speed presses running and architectural budgets healthy. Discover why leading 202 stainless steel fittings suppliers worldwide are switching to this lean-alloy powerhouse for decorative, structural and light-duty fluid systems.
What are 202 Stainless Steel Fittings? (UNS S20200)
202 stainless steel fittings are nitrogen-strengthened, manganese-rich austenitic components that maintain full non-magnetic properties and excellent formability. The balanced chromium (17–19 %) and manganese (7.5–10 %) content provides urban corrosion resistance, while nitrogen (≤0.25 %) boosts yield strength above 350 MPa—far exceeding 201-cost ratios. Compared with 201, 304, or 316, 202 stainless steel properties include better work-hardening rate and price stability, making them the first choice for cost-conscious projects that still demand 304-like aesthetics and strength.

Key Advantages of 202 Stainless Steel Fittings
- 30–40 % Lower Cost than 304 Fittings – Stable Mn/Ni ratio shields you from LME nickel spikes; lower 202 stainless steel fittings price.
- Higher Yield and Tensile Strength than 201 Grade – 350 MPa yield allows thinner walls without deformation.
- Excellent Cold Forming and Deep Drawing Capability – High n-value achieves complex reducer shapes without edge cracking.
- Good Weldability and Bright Polished Appearance – 600G mirror finish achieves luxury reflectivity for decorative elbows.
- Price-Stable Due to Lower Nickel Content – Large inventory keeps lead times short and budgets predictable.
Wide Applications
- Architectural Handrails & Balustrades: Mirror-polished 202 stainless steel fittings for handrail – elbows, tees, flanges for luxury balconies and shopping malls.

Frequently Asked Questions
Q1: What is the difference between 202 and 304 stainless steel fittings?
A: 202 uses manganese and nitrogen to replace most nickel, giving 30–40 % lower cost and similar urban corrosion resistance, but slightly less pitting resistance than 304.
Q2: Are 202 stainless steel fittings food safe?
A: Yes, they meet FDA and GB 4806.9 for non-acidic food contact; widely used for display racks and conveyor frames.
Q3: Can 202 fittings be used outdoors?
A: Suitable in urban or low-chloride environments; for coastal salt-spray, 316 is recommended.
Q4: Is 202 stainless steel magnetic?
A: Essentially non-magnetic in annealed condition; permeability <1.005 even after cold forming.
Q5: Why are 202 fittings much cheaper than 304?
A: Reduced nickel raw-material cost and more stable alloy pricing shield buyers from LME nickel volatility.
Q6: Can 202 fittings be welded with 308L or 309 filler?
A: Yes, ER308L is compatible; for color match use ER202 or ER309L.
Q7: Is 202 stronger than 201 stainless steel?
A: Yes, 202 offers ~15 % higher yield strength and better corrosion resistance due to higher chromium and nitrogen content.
