Stainless Steel 202 Boiler Tubes are high-quality austenitic stainless steel tubes manufactured by Sumer Metal Industries Private Limited, a leading manufacturer, supplier, and exporter. These tubes are designed to offer excellent corrosion resistance, durability, and strength at a cost-effective price compared to higher-grade stainless steels like 304 and 316. The tubes are ideal for applications in industries where moderate corrosion resistance is sufficient.
Sumer Metal Industries exports Stainless Steel 202 Boiler Tubes to countries across the globe, including Oman, Qatar, Saudi Arabia, the UAE, Kuwait, Spain, Germany, the USA, Canada, and several regions in Africa. Their extensive export network ensures timely delivery and compliance with international standards such as ASTM A249, ASTM A269, and ASTM A554. Both seamless and welded tube options are available to meet diverse industrial requirements.
These boiler tubes are manufactured with precision to meet stringent specifications. They are available in various outer diameters ranging from 6 mm to 114.3 mm, wall thicknesses between 0.8 mm and 4 mm, and lengths from 1 meter to 12.5 meters. The tubes can be supplied with plain or beveled ends, making them suitable for welding and other installation methods.
The chemical composition of Stainless Steel 202 Boiler Tubes is carefully controlled to ensure optimal performance. Key elements include Carbon (≤0.15%), Manganese (7–10%), Silicon (≤1%), Chromium (17–19%), Nickel (4–6%), Nitrogen (≤0.25%), Phosphorus (≤0.06%), and Sulfur (≤0.03%). This composition gives the tubes excellent corrosion resistance, moderate mechanical strength, and good toughness for various industrial applications.

❓ Frequently Asked Questions (FAQs)
1. What is the primary advantage of using Stainless Steel 202 Boiler Tubes?
The primary advantage is their cost-effectiveness due to the reduced nickel content compared to higher-grade stainless steels, while still offering good corrosion resistance and durability.
2. Are Stainless Steel 202 Boiler Tubes suitable for high-temperature applications?
While Stainless Steel 202 Boiler Tubes offer moderate strength and toughness, they are not recommended for prolonged exposure to high-temperature environments.
3. What welding methods are compatible with Stainless Steel 202 Boiler Tubes?
Standard welding methods such as TIG and MIG are compatible, but precautions should be taken to avoid carbide precipitation and ensure optimal weld quality.
