EN10025-2 S235/S275/S355 Carbon Steel Coil
EN10025-2 steel coil is a low-alloy high-strength structural steel, which is made of carbon structural steel (Wc = 0.16%~ 0.2%) by adding a small amount of alloying elements. EN10025-2 steel coil has good welding performance, plasticity, toughness and processing technology, good corrosion resistance, high strength and low cold brittle critical transition temperature.
API is an acronym for the American Petroleum Institute and is considered the most authoritative and comprehensive principle in the oil and gas industry. API 5B and API 5CT are mainly used for oil casing. API 5CT oil casing can be divided into seamless steel pipe and welded steel pipe, welded steel pipe mainly refers to the straight seam steel pipe, large diameter oil casing is generally submerged arc welding straight seam steel pipe.
Grade 316 stainless steel is an austenitic form of stainless steel with a molybdenum content of 2-3%. The addition of molybdenum makes the metal more resistant to pitting and corrosion and improves its resistance to exposure to high temperatures. This grade of stainless steel is particularly effective when used in acidic environments. With this metal, corrosion caused by acetic acid, hydrochloric acid and other forms of acid can be prevented.
Grade 904L is an unstable low carbon high alloy austenitic stainless steel. The addition of copper to this grade greatly increases its resistance to strong reducing acids, especially sulfuric acid. It is also highly resistant to chloride attack, including pitting/crevice corrosion and stress corrosion cracking.
202 stainless steel is an austenitic chromium-nickel-manganese alloy. It has high ductility, good corrosion resistance and excellent toughness in both high and low temperature environments. 202 stainless steel is one of the most widely used 200 series stainless steel. 202 stainless steel, the austenitic structure is stabilized by the addition of nickel and manganese, thereby preventing the formation of harmful phases, such as sigma phase or chromium carbide. The high nickel content also improves the corrosion and oxidation resistance of the steel at high temperatures.
A516 Pressure Vessel Carbon Steel Coil
ASTM A515 is the same as ASME SA-515 and is the standard specification for welding carbon steel pressure vessel plates for high temperature service in boilers and other pressure vessels. A515/SA-515 plate can be divided into 3 grades according to its minimum tensile strength: grade 60, grade 65 and grade 70.
