A514 Gr H alloy steel plate, Q195 and Q235 belong to carbon structural steel, which are mainly used in buildings and engineering structures such as workshops, bridges, ships, etc. Of course, there are many differences between Q195 steel and Q235 steel. 1. Different components. The chemical composition of Q195 steel: C ≤ 0.12, Si ≤ 0.30, Mn ≤ 0.50, P ≤ 0.035, S ≤ 0.040. The chemical composition of Q235 steel: C ≤ 0.22, Si ≤ 0.35, Mn ≤ 1.40, P ≤ 0.045, S ≤ 0.050. 2. The prices of A514 Gr H alloy steel plate, Q235 steel is higher than that of Q195 steel. 3. The mechanical properties of Q195 and Q235 steel are different. The tensile strength of Q195 steel is ≥390 MPa, yield strength is ≥195 MPa, and the elongation is ≥ 30%. The tensile strength of Q235 steel is 490 MPa, yield strength is ≥235 MPa, and the elongation is 23%.
Pressure vessel plates A514 Gr H alloy steel plate are used to manufacture pressure vessel equipment in petrochemical, gas separation and gas storage and transportation equipment. It is required to have sufficient strength and toughness, good welding performance and hot and cold processing performance. The general heat treatment of Q345R plate is hot rolling, controlled rolling, normalizing. The impact temperature is normal temperature, 0 ° C, -20.
Different from A514 Gr H alloy 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.
ASTM A285 grade A standard specification for pressure vessel plates. A514 Gr H alloy steel plate, carbon steel, low- and intermediate-tensile strength. ASTM A285 grade A plates are normally supplied in the as-rolled condition. The plates may be ordered normalized or stress relieved, or both.Supplementary Technology: HIC Test I NACE MR0175 1 215 | Z25 | 235 | S57 | S57.1| S58 | S58.1 1S3 |S4 Thickness: 6MM to 300MM.Width: 1500mm to 4050mm.
