Product Description

ASTM A320 L7/L7M low-temperature studs are products made of ultra-high strength steel. They exhibit high strength and toughness, good hardenability, a high fatigue limit, and multiple impact resistance after quenching and tempering treatment. With excellent impact toughness at low temperatures, they are an ideal choice for manufacturing large and medium-sized plastic molds. These studs are resistant to high and low temperatures, high pressure, and corrosion, making them widely used in various fields such as pressure vessels, petroleum and petrochemical industries, pump valves, heat exchangers, and more. Additionally, they meet the needs of customers requiring strength, toughness, and resistance to quenching and tempering brittleness, providing comprehensive and stable performance for your project. If you seek a durable and efficient stud product, ASTM A320 L7/L7M low-temperature studs are undoubtedly your best choice. They not only meet requirements for strength and toughness but also stabilize performance in high, low, high-pressure, and corrosive environments. Whether you are manufacturing pressure vessels or petroleum and petrochemical engineering equipment, this product offers reliable and high-quality service.

Common defects in rolling threads include surface cracks or scratches on the threaded part, random buckling, and out-of-round threaded parts. While a large number of these defects are typically discovered during the processing stage, even small quantities can cause issues during production, leading to trouble for users. Therefore, it's essential to summarize and control key processing conditions during production to mitigate these defects.

Carbon steel materials are categorized into low carbon steel, medium carbon steel, high carbon steel, and alloy steel based on their carbon content. Low carbon steel has a carbon content of C% ≤ 0.25% and is primarily used for grade 4.8 bolts. Stainless steel is further categorized into different grades such as 201, 304, 316, and 316L, with higher grades offering better corrosion resistance and high-temperature resistance due to variations in nickel (Ni) content. Higher Ni content enhances corrosion resistance and strengthens the material's ability to withstand high temperatures.

The performance grade label of bolts comprises two sets of numbers representing the nominal tensile strength value and yield strength ratio of the bolt material. For example, bolts with a performance level of 8.8 represent their tensile strength and yield strength ratio.
