Chemical composition of A182 F321/1.4541 Threaded Flange : carbon C: ≤ 0.08. Silicon Si: ≤ 1.00. Manganese Mn: ≤ 2.00. Sulfur s: ≤ 0.030. Phosphorus P: ≤ 0.035.
S32168/A182 F321/1.4541 TH Flanges is the label of EU BSEN standard, and the corresponding material number is x6crniti1810.
The raw material of A182 F321/1.4541 Threaded Flange is austenitic stainless steel, corresponding to the Chinese brand: 06cr18ni11ti/0cr18ni11ti.
A182 F321/1.4541 Threaded Flange have the advantages of both austenitic and ferritic stainless steels and have superplasticity. The raw material of A182 F321/1.4541 Threaded Flange is stainless steel with about half of austenite and half of ferrite. When the carbon content is low, the chromium (CR) content is 18% - 28%, and the nickel (Ni) content is 3% - 10%. Some steels also contain Mo, Cu, Si, Nb, Ti, N and other alloy elements.
A182 F321/1.4541 Threaded Flange this kind of steel has the characteristics of both austenite and ferritic stainless steel. Compared with ferrite, it has higher plasticity and toughness, no room temperature brittleness, significantly improved intergranular corrosion resistance and welding performance. At the same time, it also maintains the 475 ℃ brittleness of ferritic stainless steel, high thermal conductivity and superplasticity.
Compared with austenitic stainless steel flanges, A182 F321/1.4541 Threaded Flange have high strength and significantly improved resistance to intergranular corrosion and chloride stress corrosion. A182 F321/1.4541 Threaded Flange duplex stainless steel has excellent pitting corrosion resistance and is also a nickel saving stainless steel.
