Notes:

1. Composition values are in weight % (balance Fe).  

2. Mechanical properties are typical values (may vary with heat treatment).  

3. Austenitic grades (304, 316) are non-magnetic, corrosion-resistant, and ductile.  

4. Martensitic grades (410, 420) are hardenable by heat treatment.  

5. Ferritic grades (430) are magnetic with moderate corrosion resistance.  

6. Duplex grades (2205, 2507) offer high strength and corrosion resistance. 

Product Inspection

Generally, steel products will undergo some inspections before shipment to ensure that the products are delivered to customers perfectly, such as appearance inspection, size inspection, chemical composition inspection, mechanical property inspection. In addition, there are inspection items such as non-destructive testing and weather resistance testing. Customers can choose and apply according to different needs and scenarios.

By the way, we can also accept third-party inspections, such as SGS, BV etc.
