Product Details
The standard for the implementation of stainless steel rod is hot-rolled and forged stainless steel rod: GB/T1220-2007; Cold working stainless steel bar: GB4226.
For American standard is ASTM A276-2011,for easy working stainless steel rob is ASTM A582-2011,ASME SA276-2010,ASME SA484-2010.
Stainless steel rod has broad application prospects, is widely used in hardware kitchenware, shipbuilding, petrochemical, machinery, medicine, food, electric power, energy, building decoration, nuclear power, aerospace, military industry and other industries. Seawater with equipment, chemical, dye, paper, oxalic acid, fertilizer production equipment; Food industry, coastal facilities.
321 stainless steel is Ni-Cr-Mo austenitic stainless steel, its performance is very similar to 304, but because of the addition of titanium metal, so that it has better grain boundary corrosion resistance and high temperature strength. The formation of chromium carbide is effectively controlled by adding titanium metal.
321 austenitic stainless steel has good corrosion resistance in the atmosphere and is widely used in petrochemical, electric power, bridge and automobile industries.
Stainless steel round bar is a kind of cylindrical stainless steel products, widely used in automobile parts, aviation, aerospace hardware tools, chemical industry and other industries.
| 300series :chromium nickel Austenite Stainless Steel | |
| 301 | Good ductility for molding products. It can also be quickly hardened by mechanical processing. Good weldability. The wear resistance and fatigue strength are better than 304 stainless steel |
| 302 | Corrosion resistance with 304, due to relatively high carbon and therefore better strength |
| 303 | It is easier to machined than 304 by adding a small amount of sulfur and phosphorus. |
| 304 | General model; So 18/8 stainless steel. The standard ingredient is 18 % chromium and 8 % nickel. For non magnetic stainless steel, can not be changed by heat treatment of its metallographic structure. |
| 304L | Same characteristics of 304, but low carbon so more corrosion resistance, easy heat treatment, but poor mechanical suitable for welding and not easy heat treatment products. |
| 304 N | Same characteristics of 304,is a kind of stainless steel containing nitrogen, nitrogen is to improve the strength of steel. |
| 309 | Compared with 304 has better temperature resistance, temperature resistance up to 980℃ |
| 309 S | With a lot of chromium, nickel, heat resistance, oxidation resistance, such as: heat exchanger, boiler components, jet engine |
| 310 | High temperature oxidation resistance, the highest operating temperature of 1200℃ |
| 316 | Addition of molybdenum gives it a special structure that is resistant to corrosion. It is also used as "Marine steel" because of its better resistance to chloride corrosion than 304. SS316 is usually used in nuclear fuel reprocessing units. Grade 18/10 stainless steel is also usually qualified for this application class |
| 316L | Low carbon, more corrosion resistance, easy heat treatment |
| 321 | Addition of Titanium,lower the risk of weld corrosion |
| 347 | Addition of Niobium for stabilizing, used for welding aerospace parts and chemical equipment |
