2507 Duplex Stainless Steel Plate
2507(UNS S32750) is an ultra-duplex stainless steel containing 25% chromium, 4% molybdenum and 7% nickel. It is designed for demanding applications that require excellent strength and corrosion resistance, such as chemical processes, petrochemicals and seawater equipment. The steel has excellent resistance to chloride stress corrosion cracking, high thermal conductivity and low coefficient of thermal expansion. High chromium, molybdenum and nickel levels provide excellent resistance to pitting, crevice corrosion and general corrosion.
2205 Duplex Stainless Steel Plate
Duplex 2205 is a two-phase, ferritic, austenitic, 22% chromium, 3% molybdenum, 5% to 6% nickel alloy stainless steel. It is the most widely used duplex stainless steel grade and is characterized by high yield strength, which is twice that of standard austenitic stainless steel grades. It also exhibits good fatigue strength and excellent resistance to stress corrosion, cracking, pitting, erosion and general corrosion in harsh environments.
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.
305 stainless steel is an austenitic chromium-nickel stainless steel with a low work hardening rate. This low work hardening rate makes it suitable for many deep drawing applications. In order to minimize the earrings during the drawing process, the directionality introduced during the cold rolling process must be kept to a minimum.
316Ti(UNS S31635) is a titanium stabilized version of 316 molybdenum-containing austenitic stainless steel. 316 alloys are more resistant to general corrosion and pitting/crevice corrosion than traditional chromium-nickel austenitic stainless steels such as 304.
301 grade stainless steel is a common austenitic stainless steel with good corrosion resistance and high carbon content, and can be cold worked to various temperatures. Among stainless steels, 301 is the most easily strengthened steel by cold deformation. Cold deformation processing can improve the strength and hardness of steel, and retain sufficient plasticity and toughness. In addition, this steel has good rust resistance under atmospheric conditions, but its corrosion resistance in reducing media is poor, and its corrosion resistance in chemical media such as acid, alkali and salt is poor. Therefore, it is not recommended for corrosive environments.
302 stainless steel is a variant of 18% chromium and 8% nickel austenitic stainless steel. This alloy is the most common and frequently used alloy in the stainless steel family. 302 are slightly higher carbon versions of the 304, usually in the form of ribbons and wires. It is a tough, tough grade, has considerable corrosion resistance, is non-magnetic, and cannot be hardened by heat treatment. 302 are typically used in their annealed state and have a high degree of ease of manufacture and formability.
303 grade stainless steel is also called 1.4305 stainless steel, and 303 grade is the easiest to process of all austenitic stainless steels. The machinability properties of the 303 grade are due to the presence of sulfur in the steel elements. Sulfur can improve machining, but it also reduces corrosion resistance and toughness. The corrosion resistance of the 303 type is lower than that of the 304 type, but the toughness is still as excellent as other austenitic grades.
