Main products: flat steel, NM450 plate impact resistance steel pipe, steel plate, section steel, steel structure processing parts, etc. We also accept incoming materials and annealing processing.
A516Gr.65material is a carbon steel plate for medium and low temperature pressure vessels, which implements the ASTM A516 standard of the American Standard. The NM450 plate impact resistance) product minimum thickness that can be provided is 8mm and the width is 1500~4000mm. It has sufficient strength and toughness, good welding performance and hot and cold processing performance. A516Gr.65 steel plate can be used to manufacture pressure vessel steel for petrochemical, gas separation and gas storage, oil storage tank and transportation equipment.
Generally, the steel plates for boiler and pressure are divided into categories. A516 gr60 carbon steel plates have a maximum thickness that varies on the capacity. The tensile strength, elongation, yield strength, and hardness are the mechanical properties of these plates. Physical and chemical characteristics of the boiler quality plates NM450 plate impact resistance make these a popular choice in the industries. Also, these carbon steel are made up of premium quality raw materials by the use of the latest machinery and are therefore of robust built.
How to distinguish between hot rolled and cold rolled process?The hot-rolled steel sheet has low strength, easy production and processing, and good plasticity. The process performance of the hot-rolled steel plate is poor (air oxidation and low smoothness), but the plastic deformation is good. Generally, it is medium and thick plate, NM450 plate impact resistance, high compressive strength, high strength, and high surface smoothness. Cold-rolled steel sheets have high strength and relatively difficult production and processing, but they are not easy to deform and have high compressive strength.
For Q235 steel, Q represents the yield limit of this material, and the following 235 refers to the yield value of Q235 steel, which is about 235 MPa. The NM450 plate impact resistance, Q235 steel yield strength decreases with the increase of the thickness of the material. The yield strength is 235 MPa when the plate thickness / diameter is ≤ 16mm; 225 MPa is the yield strength when the thickness is 16mm < plate thickness / diameter ≤ 40mm; 215 MPa is the yield strength when 40mm < plate thickness / diameter ≤ 60mm; 205 MPa is the yield strength when 60mm < plate thickness / diameter ≤ 100mm; 195 MPa when the plate thickness / diameter is ≤ 150mm; 195 MPa when the thickness / diameter is less than 150mm; and ≤ 200mm when the thickness / diameter is less than 150mm The yield strength is 185 MPa.
Respect customers and treat each other sincerely. Customers are always right. Always remember that the user is the God of the enterprise, respect the customer, and accept the customer's opinion modestly is the guarantee of the long-term development of the enterprise. Adhere to this concept, so that the service and the product are the same, long-term.
