Frequently Asked Questions
Q
What is 2205 duplex stainless steel and what makes it different from standard grades like 304 or 316?
2205 duplex stainless steel (UNS S32205) features a dual-phase microstructure of austenite and ferrite. Compared to standard 304 or 316, it offers approximately twice the yield strength and significantly superior resistance to chloride-induced stress corrosion cracking, making it ideal for demanding industrial environments.
Q
What thickness and width options are available for your stainless steel sheets and plates?
We supply cold rolled sheets from 0.3mm to 4mm, hot rolled plates from 3mm to 100mm, and widths ranging from 1000mm up to 2000mm. Custom dimensions are available upon request to meet your specific project requirements.
Q
Which international standards do your stainless steel sheets comply with?
Our stainless steel sheets and plates comply with major international standards including ASTM A240, ASME SA-240, JIS, SUS, GB, DIN, and EN. All products are tested and certified to ensure full compliance before shipment.
Q
What surface finishes are available, and how do I choose the right one for my application?
We offer a wide range of surface finishes including 2B, BA, No.1, No.4, 8K Mirror, HL (Hairline), Embossing, and Satin. For decorative or architectural applications, 8K Mirror or HL finishes are popular. For industrial use, 2B or No.1 are typically preferred for their durability and functionality.
Q
What are the typical lead times and payment terms for bulk orders?
Standard lead time is 7–15 working days after receipt of a 30% deposit. We accept payment via TT (Telegraphic Transfer) or LC at sight. The balance of 70% is due before shipment. For large bulk orders, please contact us directly to discuss customized arrangements.
Q
What industries and applications are these stainless steel plates most commonly used in?
Our stainless steel sheets and plates are widely used across industries including oil & gas (offshore platforms), chemical processing (pressure vessels, chemical tanks), food and beverage, construction (architectural facades, roofing), marine engineering, heat exchangers, elevators, kitchen equipment, and advertising nameplates.
