Frequently Asked Questions
Q
What is 2205 duplex stainless steel and why is it better than standard grades?
2205 duplex stainless steel (UNS S32205) has a dual-phase microstructure of austenite and ferrite. This gives it roughly twice the yield strength of standard 304 or 316 grades, along with superior resistance to stress corrosion cracking, pitting, and crevice corrosion—making it ideal for demanding industrial environments.
Q
What thicknesses and widths are available for these stainless steel sheets?
Sheets are available in thicknesses ranging from 0.3mm (cold rolled) up to 100mm (hot rolled), and widths of 1000mm, 1219mm, 1240mm, 1500mm, 1800mm, and 2000mm. Custom dimensions can also be arranged based on your specific requirements.
Q
Which international standards do these stainless steel plates comply with?
These plates comply with multiple international standards including ASTM A240, ASME SA-240, JIS, SUS, GB, DIN, AISI, and EN standards. This ensures they meet strict quality and performance requirements for global applications.
Q
What are the typical applications for 2205 duplex stainless steel sheets?
Common applications include pressure vessels, heat exchangers, offshore oil and gas platforms, chemical processing tanks, desalination plants, marine equipment, and structural components where high strength and excellent corrosion resistance are critical.
Q
What welding methods are compatible with 2205 duplex stainless steel?
2205 duplex stainless steel is compatible with common welding methods including TIG (GTAW) and MIG (GMAW). It is generally easy to fabricate and form, even into complex shapes. Proper filler material and heat input control are recommended to maintain the balanced microstructure and corrosion resistance.
Q
What are the payment terms and lead time for orders?
Standard payment terms are 30% TT deposit with the 70% balance payable by TT or LC at sight before shipment. Lead time is typically 7–15 working days after receipt of the deposit. Bulk orders and custom sizes are welcome—please contact us for a tailored quote.
