SS 201 Round Bar Supplier and UNS S20100 Material Stock
GNEE Stainless steel is one of the most trusted SS 201 stainless steel manufacturers and has been certified to ISO 9001:2008. Currently, our supplied 201 stainless steel round bars cover diameters from φ5mm to φ200mm, with lengths customizable according to your requirements (standard 6 meters, supporting fixed-length cutting), suitable for diverse scenarios from precision parts processing to large-structure manufacturing. Each round bar is strictly produced in accordance with ASTM A276 standards, supporting customized processing such as surface polishing to meet your diverse processing needs.
We offer a wide variety of 201 stainless steel round bar conforming to ASTM A276. With low carbon (≤0.15%), high manganese (5.5%-7.5%), and nickel (3.5%-5.5%) as primary alloying elements, this material is an economical austenitic stainless steel and a cost-effective alternative to 304 stainless steel. It is suitable for moderately corrosive environments up to 60°C, but is susceptible to pitting and crevice corrosion in warm chloride environments and stress corrosion cracking above 60°C.

Quality Inspection
Chemical composition is verified via PMI (Positive Material Identification) or optical emission spectrometry, while properties such as tensile strength, yield strength, elongation, and hardness are tested to ensure compliance with specifications. Dimensional inspections typically cover diameter tolerances, straightness, and surface condition. Each batch is traceable by heat number and is accompanied by an EN 10204 3.1 Material Test Certificate (MTC).
GNEE Product Packaging
Type 201 stainless steel round bars are packaged to meet export shipping requirements, designed to protect their bright or machined surfaces from damage during handling and transit. The bars are typically bundled using steel or fiber strapping into units weighing approximately 1 to 3 tonnes, with an outer layer of plastic film or waterproof paper for protection. For containerized shipping, wooden pallets or reinforced crates are generally used to ensure stability.
FAQ
Q: How does Type 201 compare to Type 304?
Composition: Compared to Type 304, Type 201 has a significantly higher manganese content (up to 7.5%) and a lower nickel content (3.5%–5.5%).
Strength: The yield strength of Type 201 is approximately 30% higher than that of Type 304.
Corrosion Resistance: Type 201 is inferior to Type 304. It is suitable for mild environments but may rust in high-humidity, chemically corrosive, or marine environments.
Q: Is Type 201 stainless steel magnetic?
A: In the annealed state, Type 201 stainless steel is non-magnetic. However, like other austenitic stainless steels, it may exhibit slight magnetism after cold working (such as stretching, bending, or machining) due to the partial transformation of austenite into martensite.
Q: Can Type 201 be used outdoors?
A: It depends on the specific environment.
Suitable: Dry environments or urban areas with low pollution levels.
Not Suitable: Coastal areas (salt-laden air), heavy industrial zones, or regions prone to acid rain. In these environments, Type 304 or 316 should be used to prevent "tea staining" or surface rust.
Q: Is Type 201 more difficult to machine than Type 304?
A: Yes. Due to its higher nitrogen content and higher work-hardening rate, Type 201 is harder and causes more significant tool wear.
Recommendation: Use high-quality carbide tools, employ lower cutting speeds, and maintain a constant feed rate to prevent the material from work-hardening during the cutting process.
