Based on the advantages of A709 Gr 50W carbon steel plate steel resources in domestic market and good reputation, combining with the huge international market demand for steel products, our company started the international business in 2010 and successfully being approved and certified by ISO9001:2008, the Registration number is 626014Q11531R0S. With the quality steel A709 Gr 50W carbon steel plate products and professional service, our company was award the international acclaim from infrastructure, shipbuilding, petroleum industry etc., and gradually grow into a bright star in the steel export industry .
ASTM A633 material is particularly suited for service at low ambient temperatures and higher where notch toughness better than that expected in as-rolled material of a comparable strength level is desired. A709 Gr 50W carbon steel plate, A633 Grade E high-strength low-alloy structural steel provides a minimum yield point of 60 ksi [415 MPa] in thicknesses up to 4.0 in. [100 mm], inclusive and 55 ksi [380 MPa] in thicknesses over 4 in. to 6 in. [100 to 150 mm], inclusive.
Compared with 15Cr steel, 20Cr alloy has higher strength and hardenability. The critical hardening diameter in oil is 4-22mm, and the critical hardening diameter in water is 11-40mm, but the toughness is poor. This A709 Gr 50W carbon steel plate alloy steel A709 Gr 50W carbon steel plate still has a tendency to grow grains during carburization, and direct quenching at lower temperature has a greater impact on impact toughness, so secondary quenching is required after carburization to improve the toughness of the core of the part, and there is no temper brittleness.
The composition characteristics of low alloy high strength steel are low carbon ≤0.20%, low alloy, and total alloying elements is less than 3%. The low carbon content is to meet the process performance requirements of A709 Gr 50W carbon steel plate, low alloy high strength steel for engineering structural parts such as plasticity, toughness, weldability and cold deformation; adding a small amount of alloying elements (mainly Mn) to achieve the purpose of improving mechanical properties. Mn not only has a significant strengthening effect on ferrite, it can also reduce the cold brittle temperature of steel, increase the amount of pearlite in the steel, and further improve the strength.
15Mo3 steel plate is used for boiler and high temperature pressure vessel.15Mo3 steel plate executive standard: DIN17155Delivery status of A709 Gr 50W carbon steel plate, 15Mo3 steel plate: normalizingNormalizing temperature of 15Mo3 steel plate: 650 ~ 700 ℃Normalizing time of 15Mo3 steel plate: 1.5t-2.5t15Mo3 welding repair: welding repair can only be carried out after the approval of the purchaser.Requirements for tensile properties of 15Mo3 steel plate: tensile strength 450-600 MPa, yield strength 270 MPa.
