The company has A709 Gr 50W low alloy steel sheet advanced production equipment and machining technology, excellent marketing team and domestic regional channel partners, and sound management plan for product market development and after-sales service. After years of cooperation experience A709 Gr 50W low alloy steel sheet, we have accumulated a large number of customers at home and abroad, and won unanimous praise.
Customer service center has provided after-sales service for many large-scale information systems, and has accumulated rich working experience in the process of A709 Gr 50W low alloy steel sheet service for many years. It can provide accurate, timely and high-quality support and service for users, which is well received by users.
Smelting process of A709 Gr 50W low alloy steel sheet, container plate SPA-H weather-resistant steel: The molten iron for smelting SPA-H steel must be pretreated by molten iron desulfurization. Before entering the converter, the sulfur content of the molten iron is ≤0.010%, and the slag on the surface of the molten iron is cleaned. Nickel plates, copper particles or nickel-copper alloys are added to the converter with scrap steel. The carbon content of the converter smelting end is required to be less than 0.06% to prevent the molten steel from being oxidized.
Shipbuilding steel plates are used to manufacture the hull of marine and inland ships. High strength, plasticity, toughness, cold bending performance, welding performance and corrosion resistance are required for shipbuilding steel plates. Boiler steel plates are used to manufacture various boilers and important accessories. As the boiler steel plate works under medium temperature (below 350℃) and high pressure, it is also subject to impact, fatigue load and water and gas corrosion. The A709 Gr 50W low alloy steel sheet, boiler steel plate is required to ensure a certain strength and have good welding and cold bending properties.
API 5L steel is pipeline steel mainly for use in oil and gas industry. API 5L steel has PSL1 and PSL2 levels. For same API 5L steel grade, the carbon content for PSL1 is higher than PSL2. Meanwhile, the API 5L PSL2 steel has more strict requirement for P, S content than API 5L PSL1 steel, A709 Gr 50W low alloy steel sheet. Therefore, API 5L PSL2 steel strength is higher than API 5L PSL1 steel strength. For example, API 5L X42 PSL2 yield strength is 317-524 MPa, tensile strength is 434-758 MPa. While API 5L X42 PSL1 yield strength is 290 MPa min. , tensile strength is 414 MPa min.
Our company will accept the product quality objection registration record, pass it to the A709 Gr 50W low alloy steel sheet production unit and relevant departments, and timely coordinate the supervision of product A709 Gr 50W low alloy steel sheet quality objection. Our company coordinates the relevant department personnel to the customer unit to carry on the investigation, the processing.
