300 Series: chromium - nickel austenitic stainless steel 301: scalability blurted car muffler pipe, for molding products. It can also be rapidly hardened by mechanical processing. Good weldability. Abrasion resistance and fatigue strength than 304 stainless steel. 302: 304 with corrosion resistance, due to relatively high carbon intensity and therefore better. 303: by adding a small amount of sulfur and phosphorus to more than 304 cutting. 304: is a versatile stainless steel, it is widely used to produce good overall performance requirements (corrosion resistance and formability) of equipment and parts. 304 stainless steel is a grade produced in accordance with the ASTM standard stainless steel. 304 equivalent to China's 0Cr19Ni9 (0Cr18Ni9) stainless steel. 304 19% chromium car muffler blurted tube pictures, 9% nickel. 304 is the most widely used stainless steel, heat-resistant steel. For food production equipment, past through chemical equipment, nuclear energy. 409: the cheapest model (England), commonly used as automobile exhaust pipe car muffler blurted tubes offer, is a ferritic stainless steel (chrome steel). 409L: 400-series stainless steel is a typical representative of the low carbon steel, titanium and containing about 11% Cr, it is generally used as heat-resistant steel. The steel has excellent workability and weldability car muffler blurted tube, with appropriate temperature characteristics and corrosion resistance at room temperature, the main purpose is to feed resistant equipment. 409L features make it widely used in automotive exhaust pipe components, heat exchangers, heat equipment, but also can be applied to the lower West tableware, electronic components. After hard state after dealing 409L containers can also be used.
