409 Stainless Steel Strips From JawaySteel
409 stainless steel strips from jawaysteel is commonly used ferritic stainless steel in mechanical and construction engineering.Because of the presence of austenitic grains, the mechanical properties are greatly improved. Moreover, due to the addition of a lot of alloying elements, the strength and hardness have been greatly improved.
409 stainless steel, cheapest model (UK and us), usually used as automobile exhaust pipe, is ferritic stainless steel (chrome steel).
409 stainless steel strips chemical composition:
Carbon C: 0.08 or less
Manganese Mn: 1.00 or less
Si Si: 1.00 or less
Chromium Cr: 10.5 ~ 11.75
Ni Ni (2) : 0.50 or less
P P: 0.045 or less
S: sulfur 0.03 or less
Ti Ti: (6 ~ 0.75 c)
Note: all single values are the highest unless otherwise specified; For some pipe making process, some models of austenitic stainless steel nickel content must be slightly higher than the value shown in the table; (3) random; The maximum Ta content is 0.10%; (5) the highest content is 0.75%; The maximum content is 0.70%.
409L stainless steel has strong resistance to corrosion, high temperature and fatigue, which can realize the life of exhaust system components and lightweight.
409L high temperature resistance, can achieve high efficiency of the engine and exhaust system, and reduce the exhaust system thickness, can reduce the exhaust emissions.
409L is a new product with low cost, good flexibility, high yield and easy replacement.
409L steel has almost no transition from high temperature to low temperature, so the grains are easy to grow up and appear coarse ferrite structure with low strength. In continuous casting, when the slab is cut up, it is prone to bend, which affects normal production. The main problem in the crystallization of 409L steel is the performance degradation caused by the grain size.
Never be afraid to bother me, it is no matter if you have the regular supplier, just take a consideration while our products are the best price and high quality.
