The cold rolling precision bright pipe system produced by our factory has smooth appearance, uniform wall thickness, no oxide layer and high precision. The inner hole of ASTM A588 structural steel plate steel pipe can be divided into round, spline and plum blossom, which is widely used in automobile, motorcycle, electric power, petrochemical, ship, aerospace, bearing, pneumatic components, oil cylinder, boiler equipment, medical equipment, fitness equipment and other industries. Materials can be divided into: 10#, 20#, 35#, 45#, 40Cr, 16Mn, etc. According to the needs of users, we can make all kinds of national standard non-standard precision pipes. Special ASTM A588 structural steel plate materials and specifications can be ordered in advance.
The difference between q345 and q235 steel ASTM A588 structural steel plate The lower limit of yield strength of Q345 is 345MPa (the actual meaning of Q is the Chinese character ""qu"", and the standard value behind means the lower limit of yield strength). Q235 steel is used for metal structural parts, nitrided or cyanidized parts with low core compressive strength requirements, support rods, crankshafts, crane hooks, couplers, bolts and nuts, sleeve specifications, shafts and weldments.
The main metal material ASTM A588 structural steel plate used to make the boiler is steel. The main boiler body is composed of the parts which bear static load under normal temperature and the parts which bear high pressure and high temperature. The former part can be made of general structural steel, while the latter part must be made of steel with special properties, i.e. boiler steel. Boiler steel is required to have good high temperature resistance, stable structure, machining performance, etc. properties.
Different from ASTM A588 structural steel plate, the alloy wear-resistant layer of alloy plate is mainly chromium alloy, and other alloy components such as manganese, molybdenum, niobium, nickel are also added. The carbides in the metallurgical structure are distributed in a fibrous shape, and the fiber direction is perpendicular to the surface. Carbide microhardness can reach HV1700-2000 and surface hardness can reach HRC58-62. Alloy carbides have strong stability at high temperatures, maintain high hardness, and also have good anti-oxidation properties. They are fully used within 500°C.
Mechanical Properties A588 corten steel: ASTM A588 grade A is a high-strength, low-alloy steel plate utilized primarily in structural applications such as bridges and buildings. We stock this material as A588 Gr A & B in plate and 606 in sheet. Tensile: 70 ksi min (4” and under), 67 ksi min (4”-5”) 63 ksi min (over 5”-8”) Yield:50 ksi min (4” and under), 46 ksi min (4”-5”) 42 ksi min (over 5”-8”) Elongation:16% min in 8” 19% min in 2” (for plates wider than 24”)
