300 Series—austenitic chromium-nickel alloys[edit]

• Type 301—highly ductile, for formed products. Also hardens rapidly during mechanical working. Good weldability. Better wear resistance and fatigue strength than 304.
• Type 302—same corrosion resistance as 304, with slightly higher strength due to additional carbon.
• Type 303—free machining version of 304 via addition of sulfur and phosphorus. Also referred to as "A1" in accordance with ISO 3506.
• Type 304—the most common grade; the classic 18/8 (18% chromium, 8% nickel) stainless steel. Outside of the US it is commonly known as "A2 stainless steel", in accordance with ISO 3506 (not to be confused with A2 tool steel). The Japanese equivalent grade of this material is SUS304.
• Type 304L—same as the 304 grade but lower carbon content to increase weldability. Is slightly weaker than 304.
• Type 304LN—same as 304L, but also nitrogen is added to obtain a much higher yield and tensile strength than 304L.
• Type 305—same as 304, but with more nickel to decrease work hardening.
• Type 308—used as the filler metal when welding 304.
• Type 309—better temperature resistance than 304, also sometimes used as filler metal when welding dissimilar steels, along with inconel.
• Type 310 310S— is a highly alloyed austenitic stainless steel used for high temperature application. The high chromium and nickel content give the steel excellent oxidation resistance as well as high strength at high temperature. This grade is also very ductile, and has good weldability enabling its widespread usage in many applications.
• Type 316—the second most common grade (after 304); for food and surgical stainless steel uses; alloy addition of molybdenum prevents specific forms of corrosion. It is also known as marine grade stainless steel due to its increased resistance to chloride corrosion compared to type 304. 316 is often used for building nuclear reprocessing plants.
• Type 316L—is an extra low carbon grade of 316, generally used in stainless steel watches and marine applications, as well exclusively in the fabrication of reactor pressure vessels for boiling water reactors, due to its high resistance to corrosion. Also referred to as "A4" in accordance with ISO 3506.
• Type 316Ti—variant of type 316 that includes titanium for heat resistance. It is used in flexible chimney liners.
• Type 321—similar to 304 but lower risk of weld decay due to addition of titanium. See also 347 with addition of niobium for desensitization during welding.

Hongtu Metal was founded in 2006 with a registered capital of 27 million US dollars. It is a comprehensive, modern and high-quality enterprise integrating steel production, processing and sales. Since its establishment, the company has developed rapidly. It has built long-term and stable cooperative relations with Shandong Iron and Steel, Rizhao Iron and Steel, Shanxi Tisco, Shanghai Baoshan Iron and Steel, Xiwang Special Steel and other major domestic steel plants. It is the first-class agent of major steel plants and has been selected as excellent agent and excellent cooperator for many times. In order to provide better services to customers, the company has set up a professional foreign trade team to solve one-stop steel export business for customers.
