Yuhong Group: Your One-Stop Partner for Stainless Steel in Multiple International Standards

Yuhong Group is a leading stainless steel supplier in China with strong comprehensive strength. We supply stainless steel products in multiple international standards — American ASTM/UNS, European EN, Chinese GB and Japanese JIS — so that customers around the world can always find the exact grade and specification they need. No matter which standard your project is designed to, our team can provide the right material with full traceability.

Multiple Standards, Multiple Choices

Different markets and projects follow different standards. Yuhong Group masters all major standard systems and supports grade cross-reference between ASTM, EN, GB and JIS, giving customers the widest range of choices. Our main austenitic grades include:

• 201 (ASTM 201 / UNS S20100) – economical alternative for general applications
• 304 (ASTM 304 / UNS S30400) – the most versatile and widely used stainless steel
• 304L (ASTM 304L / UNS S30403) – low carbon version for improved weldability
• 316 (ASTM 316 / UNS S31600) – molybdenum-bearing grade with superior pitting resistance
• 316L (ASTM 316L / UNS S31603) – low carbon 316 for welded structures
• 310S (ASTM 310S / UNS S31008) – high temperature oxidation resistance
• 321 (ASTM 321 / UNS S32100) – titanium stabilized for high temperature service
• 904L (ASTM 904L / UNS N08904) – super austenitic for aggressive chemical environments
• 254SMO (UNS S31254) – super austenitic with outstanding chloride resistance

Duplex Stainless Steel Grades

Duplex stainless steels combine the strength of ferritic steels with the corrosion resistance of austenitic steels, making them ideal for offshore, chemical and desalination applications.

• 2205 (ASTM 2205 / UNS S32205) – the standard duplex grade with high strength
• 2507 (ASTM 2507 / UNS S32750) – super duplex for extreme corrosive environments
• 2101 (UNS S32101) – lean duplex with excellent cost efficiency
• 2304 (UNS S32304) – lean duplex for structural applications

Ferritic, Martensitic and Precipitation Hardening Grades

For applications requiring magnetic properties, wear resistance or high hardness, Yuhong Group offers ferritic grades such as 430 (ASTM 430 / UNS S43000) and 409 (ASTM 409 / UNS S40900), martensitic grades including 410 (ASTM 410 / UNS S41000), 420 (ASTM 420 / UNS S42000) and 5Cr15MoV knife steel, as well as 17-4PH (ASTM 17-4PH / UNS S17400) precipitation hardening stainless steel.
