Latham Steel, a prominent manufacturer and supplier based in Hamilton, New Zealand, specializes in high-quality SA 516 Grade 70 sheets and plates. These products are specifically designed for medium to high-pressure and elevated-temperature applications. This particular carbon steel grade is a go-to choice for fabricating boilers, pressure vessels, and heat exchangers, thanks to its remarkable toughness, weldability, and thermal stability. Latham Steel is committed to ensuring precise dimensional accuracy, consistent mechanical properties, and adherence to ASTM A516 standards. With SA 516 Grade 70, you can count on reliable performance even under high stress and fluctuating temperatures, making it a top pick for refineries, petrochemical plants, power generation units, and industrial processing equipment.
SA 516 Grade 70 is composed of carefully controlled amounts of carbon, manganese, silicon, phosphorus, and sulfur. It boasts a minimum yield strength of about 260 MPa and impressive tensile strength ranging from 485 to 620 MPa. This steel grade exhibits excellent notch toughness, particularly when normalized, and maintains stable mechanical performance even at elevated temperatures. With the right welding techniques, it offers good weldability, uniform hardness, and reliable ductility. Its well-balanced composition ensures strong resistance to brittle fracture and deformation, making SA 516 Grade 70 an ideal choice for pressure vessels and high-temperature industrial equipment.
