304l stainless steel tube factory supply price

304L stainless steel chemical chemical composition% C: ≤ 0.03, Si: ≤ 1.0, Mn: ≤ 2.0, Cr: 17.0 ~ 19.0, Ni: 8.0 ~ 11.0, S: ≤0.03, P: ≤0.035.

304 stainless steel Chemical composition C≤0.08 Si≤1.00 Mn ≤2.00 P≤0.05 S≤0.03 Cr 18.00-20.00 Ni (nickel) 8.00 ~ 10.50 –


304 stainless steel and 304L stainless steel are the main components are containing 18% chromium (Cr), 8% nickel (Ni); their main difference is that 304L stainless steel is low carbon 304 steel, in general, 304L stainless steel corrosion resistance And 304 stainless steel similar, but after welding or to eliminate stress, 304L stainless steel resistance to grain boundary corrosion is excellent.

Price 304L stainless steel is higher than 304 stainless steel, 304L stainless steel is low carbon stainless steel, mainly for welding process. In the welding, the use of 304L stainless steel can effectively reduce the welding corrosion.

According to the hardness standard points, 304 stainless steel is better than 304L stainless steel, because the level of carbon directly affect the hardness of stainless steel. In addition there are 304H stainless steel series, H said high carbon content.

304l stainless steel tube offer is:
