ASTM A403 WP316L Seamless Elbow
What is ASTM A403 WP316L stainless steel elbow?
ASTM A403 gr WP316L elbow has lower carbon content. In addition to 18% chromium and 8% nickel, the material composition of 316L pipe fittings also contains 4% molybdenum, making it corrosion resistant to chloride ion stress cracking.
ASTM A403 gr WP316 Seamless Elbow consists of carbon, silicon, manganese, sulfur, phosphorus and 18% chromium, 8% nickel and 4% molybdenum. This combination provides mechanical, chemical and physical properties to 316 fittings.
C: ≤0.03 Si: ≤1.00 Mn: ≤2.00 P: ≤0.045 S: ≤0.030 Cr: 10.00-14.00 Mo: 2.00-3.00 Ni: 16.00-18.00 SUS316L stainless steel elbow pipe fittings are an acid-resistant and anti-corrosion alloy material. There are two series of nickel stainless steel and chromium stainless steel. The products are widely used in many fields of industry and civil use.
