Before use, we conduct strict chemical composition analysis and mechanical performance tests to ensure the fasteners we produce can operate for extended periods under high temperature, high pressure, and corrosive environments.
Once the raw materials of ASTM A320 B8M Screw are selected, further processing is carried out, including spheroidizing annealing, acid pickling, and wire drawing to meet customer requirements.
Forging is a key step in the manufacturing process of ASTM A320 B8M Screw. The use of forging technology helps improve the density and strength of the material internally. During this process, the raw materials are heated to a high temperature of approximately 1100℃ to 1250℃ and then hammered to enhance overall performance, ensuring compliance with ASTM A320 standards for strength and toughness, thus meeting customer requirements. Next, we cut the forged raw materials according to specifications to meet the product's dimensional requirements. Finally, we utilize molds to perform thread processing on the formed bolts using a rolling method.
Heat treatment is an important process after thread processing. By controlling the heating and cooling cycles, we improve the hardness and corrosion resistance of the material. For the ASTM A320 B8M Screw product, our heat treatment is set within a temperature range of 600℃ to 700℃, held for 1 to 1.5 hours, followed by rapid cooling using oil or water, further increasing its tensile strength, which can reach over 800 MPa (approximately 116 ksi).
Of course, the ASTM A320 B8M Screw quality control phase is crucial. Every batch of our products undergoes rigorous testing to ensure compliance with ISO 261 and ISO 4033 standards. This includes appearance checks, tensile tests, hardness tests, and corrosion tests, guaranteeing that all products are qualified and ensuring their reliability and safety during use.
The production process of ASTM A320 B8M Screw is intricate and complex, involving multiple stages where each step is strictly conducted according to industry standards, ensuring the final product's high quality and performance.
